Well... I got bitten by a bad Carter fuel pump... I bought a brand new Muscle Car version and after a month it started puking fuel all over the bottom of my car. It looks to be leaking out of the top edge of the round pinch seal.

So I was going to buy the Delphi version but the connections are reversed from bottom to top.

Will this work for me? I didn't want to go back to the Carter.

If you just want something other than Carter and don't want to have to reroute your fuel lines (which you'd have to do with the Delphi unit you posted), since you are looking at Rock Auto, I see they list a US Motorworks model USMP16263.  I have no experience with them, so I can't give any kind of endorsement.

Yes... I saw that one but I've read several other posts that the Delphi part was a better quality. 

I don't mind rerouting the lines. It doesn't look like it would take much effort to do that.

I just don't want to buy the McRobb pump because of the price... 😳

Ive run a Delphi pump for several years.  All of the 70 and newer pumps have the lines at the bottom.

Except for the late model 78-79 AMC small cars... Like above... Is this the one you're using too?

Also... I just read several posts that the Delphi was the better part and in one of them you also mentioned it as well... And my first thought was well... "Heavy knows what's up... So that settles it...." Ha... hahaha...

If you hate money you might consider the RobbMc fuel pump. Max output 7 psi, multi-position revolving base, optional two fuel inlets mid level (found out didn't need it) the bottom has the fuel outlet.

OK, I'll relate my last go around with a fuel pump on my 232 six cylinder 69 Javelin. I've only been getting about 3 years on a fuel pump the last few years. I got 37 years off the original carter fuel pump. I've had about 4 or 5 since. The AMC sixes are a little harder to get fuel pumps for then the AMC V-8s (290 to 401)s. The is a little less choice , as some choices are not really available. Heaven help you if you need one for vacuum wipers , they just NOT available. Any way the fuel pump went bad again on the Javelin and going on the name I got a Delphi fuel pump. I put it on and went on a 15 mile round trip to the gas station and back for a little gas as the tank was very low. Next time I came back to start the car it would not run. So, I messed with it and finally determined the new Delphi  was bad after 15 minutes and 15 miles. I got a GMB pump the next go around. The difference is the Delphi pumps are NOW made in China and are now crap . The GMB pumps are made in Taiwan and seem to be good. Turns out the late Delphi pumps are now made in China and seem to be suspect. I'd imagine the Delphi pumps for the V-8s are now China also, so I'd maybe a bit aware of them also. A good Carter fuel pump would be maybe the best choice assuming they are still made in the US ,but then a lot of things are just not made her any more. LRDaum

I just looked up the part number you listed above and in the bottom of the listing is says country of origin is South Korea. I suppose that would be better than China?

Also consider calling them on the telephone and ordering a claimed USA sourced
AMC stock mechanical fuel pump from BLASER AUTO Nash Rambler AMC in Moline Illinois
( 309 ) 764-3571

Also, only as a general observation, as this comes up on basically on a weekly basis,
with a second "cheap" pump purchase one will basically be $80 to $100 "in"
plus time & effort & grief, and suspicion / doubt of second pump's "survival"...
That's already 1/2 way to a USA Made RobbMC serviceable rebuildable AMC Mechanical Fuel Pump

Just another thought...  Are you sure what you are seeing around the flange of the fuel pump is actually gas and not oil?   It's not uncommon for oil to weep from the vent hole at the top of the pump, and it could pool around that flange.

I rebuilt my old Carter with a kit from these guys (semi-local to me):

https://www.then-now-auto.com/fuel-pump-repair-kits/" rel="nofollow - https://www.then-now-auto.com/fuel-pump-repair-kits/

The kit I actually got in the mail was shipped from these guys (I think this is the exact kit):
https://www.deadnutson.com/carter-high-performance-x-fuel-pump-rebuild-kit/" rel="nofollow - https://www.deadnutson.com/carter-high-performance-x-fuel-pump-rebuild-kit/

Installation was easy,
I'm hoping it likes the crap ethanol gas better than the old diaphragm did,

and I bolted a USA pump back on my instead of something "new" from Red China.

Yep, that's the way to go if you can. Thumbs Up  A rebuildable USA Carter pump.  I did that a couple of times with the Carter fuel pump on my Studebaker, just recently with a kit from Then and Now.  Good guys there too. They also have a series of videos on YouTube on rebuilding pumps.

Supposedly they are using materials made for today's ethanol fuels, so I'm hoping it will hold up same as you.

I'm having increasingly poor results with professionally rebuilt pumps, mainly from Arthur Gould Rebuilders. Two in two years failed. One DOA, sent back and re-done (graciously) and one after a year and on the road. I don't think it's workmanship.

I've given up with them. I drive my cars often, so failure is very annoying. I'm switching to electric pushers and oil-pressure switches. Haven't figured out what to do with the wipers.

tomj .. get your self a vacuum reservior , main feed is eng vac with 5 split off nipples to run your wipers . they will run better than they ever have , and have 4 other vacuum sources left for whatever .  got mine from VMS racing ... as for as fuel pump ... will never go back to manual ... low pressure 4 to 7 lb elec. pump solves all on a 6 popper . But stay away from edelbrock ones as they fail yearly ! Rock auto rebuild services are junk ... and most of RA electrical parts are too . new mechinicals are ok from RA but thats about it .. Put 4 step down V/reg for dash gauges ( gas , temp ) and none of them worked from RA ... found one in an old cluster and it worked fine .. some 52 years old and worked great !

Called Blaser's and they do not have any American sourced fuel pumps available. 

I guess I will have to try the Delphi unit for now.

1982AMCConcord - that is interesting to hear... was about 1 year ago when speaking on the telephone with Blaser Auto about AMC Fuel Pumps, with that phonecall being the information source of what I posted before.  So like everything else as part of the big new "plan" out there for all of us if we like it or not... I guess Blaser no longer has a source... wonderful this all is ain't it ?...

Hi Phat... They have a source and they're waiting on that company to make another run of fuel pumps. They also said the other AMC vendors use the same vendor... And that they "heard" that they also don't have any in stock. I'm going to call Kennedy American just for good measure but I have a feeling that it's going to be the same all around. 🤞🤞🤞

Alright well I did purchase the USMP16263 Fuel pump. I installed it today. I then let it run for about 20 minutes before taking it on a 3 hour drive. During that time I also stopped periodically and checked for leaks. I also checked again when I got home. So far so good. I plan to drive it again tomorrow. Fingers crossed. I'll check back in the Spring once I have taken it back out of storage!

Also... Just want to mention... That the USMP pump box was marked as an ISO certified company... It is made in China but I did work for an ISO certified company myself before and we had to hold our work to a higher standard. I hope this company's certification actually means something in this case.

🤞🤞🤞

ok .. i seen what yall have had to say on this and i do agree that the carter pump is not so good. but what im looking for is a stock looking pump with 3/8's  line out to the carb that will keep up with with the needs and keep 7-8 pounds when i got my foot in it. she will have the stock (tweeked with) 4300 mostly  but when i take her to the track i will put the torker and holley on it. any ideas?

I used the USMP Model from Rock Auto and it's been fine so far... It's still early to tell but I probably put a few hundred miles on it before old man winter came a knocking. It's an ISO certified company... And I'd like to think that will lend to some degree of additional quality but only time will tell. I also have another Carter that I got as an exchange from Rock Auto. So... I'll have a back up sitting...

I returned one and then ordered another at the same time in case the first I ordered didn't work I already had the other one in the mail! I figured with all the horror stories about these pumps lately I better have a few on hand! :)

napa is the only game in town out here in the woods... everything else is like 60 miles away round trip. good thing is  as me and other amc guys and other old car guys come out of the woodwork  he is keeping things on the shelf now.  pumps .. tune up parts some gaskets. sadly most other stuff is a ups order and the extra shipping that gos with it unless ya want to wait on his stock order once a month.... its looking like a lot of the parts houses are getting smart and keeping some common stuff on the shelf now for the older cars. you would be surprised just how many 30-40-50 even 60 year old cars are folks daily drivers .... well here anyway. kinda cool going to get a filter at napa on a Saturday afternoon and the newest car in the lot is a 86 ....

Two Carter M6505 fuel pumps failed on my 360 in one week back in December. Neither one lasted more than 2000 miles. They are the small body pumps that look more like the pump used on the six-cylinder engines rather than the larger pumps V8's are supposed to use. I've never had a problem with the small body Carter pumps on sixes, but I suspect they are not meant for V8 use. Perhaps they don't have enough travel in the diaphragm and the V8's are over-flexing them. Who knows...but they fail constantly. 

Technically they were NAPA B0107-P pumps, but they are rebranded Carter M6505's. Carter has a near monopoly on our pumps. NAPA, Delphi, and a whole host of others are just reboxed Carters. 

Airtex used to make a good large body pump for our engines, but they've gone out of production since Carter bought Airtex a few years ago. Now Airtex pumps are reboxed Carter. 

I will be contacting my Carter sales representative about all of this and raising a stink. I hope they will listen and fix the problem with these pumps. 

The US Motor Works USMP-16263 seems to be our best option now for an OE replacement pump.

Try the GMB fuel pumps. They are Taiwan not China and seem to be better quality over all. They are available from Rock auto if you can find them no where else. I got one for my six cylinder Javelin after getting a bad Delphi (CHINA) fuel pump that only lasted about 15 minutes. LRDaum

The thing is I don't want a fuel pump only made for carb because I'd like to go to fuel injection eventually. Apparently Aeromotive has a dual purpose kit... If I can find something like this that would work effectively with my tank... It would certainly help...

I think you have the right idea doing an in tank pump but here's the thing, if you run a pump made for fuel injection, you'll burn it up because you'll have to reduce the pressure and volume so much to work with a carb. If you fit your tank for a fuel pump, I would suggest using a TBI type pump like this https://www.rockauto.com/en/moreinfo.php?pk=1114082&cc=1087422&pt=6256&jsn=577&_nck=Ekt6BqBF1pwlXdx0gYlm1eLc36x7RagAV9qWoBGYzks2kIIGcMG6lGcjeM2THnK59HMLqf6sMYfpcI%2FOfGWNe%2BOWe1DQpXIIdLXz9TEgncYbnmjzz1t%2Fj%2Fl5%2Ff4xpJtvKWbNDO0rGNQB9Dnt3ZHphWXEeH8MsZwxUXAK8Q1FDLbXW%2BrRhkjy0pY2Kyt05vobWOe5P0N7ATv6RFvq8gu0556bVOniTMV%2BTWa0qb2sHSVREdZ3WBIZ95U2MLV%2BmDGl3g%2B8Aypvp3oWK08Vv28zE9NlW68n8h6N1nSCFiJLdY3XYWJ7IElcshtd4ns9wThCCxQy3a36%2F4H11MP6iWxDVxup1h%2BEXWS3ZgGhE5RKH7iW4jwFUxGSr6i7FdCXemwop027ZsFvrbcogFyQT2LMSp38eztYzyPD%2BEU5ZrY7L9U%3D" rel="nofollow - https://www.rockauto.com/en/moreinfo.php?pk=1114082
because it's only putting out 15 psi and 32 gpm which is fine for a carb. Put a regulator on it and you'll be good to go. When you do switch to FI, just swap the pump and regulator and your done since the tank is already setup.
Here's how Woosterkevin and I have modified Concord tanks for FI that we run in our Javelins.





It takes more work but it's close to how OEM's have pumps in tanks so the pumps last and are quiet. We've had no issues with fuel slosh either using the long sock that's down in the lowest part of the tank. There's other ways to do it but have their drawbacks.

Thanks Mopar Guy! I didn't know about wearing out the pump prematurely by dumbing it down to carb PSI. Thanks for letting me know. 

Wow...That's a lot of options right there! I'm going to be talking to a local well known carb/fuel injection guy this weekend. He's got a few solutions available and I'm going to find out what kind of arrangement he can offer. I'll also show him these options as well. He does a lot of Sniper installs around me. 

I don't want to spend a bunch of money but if it means flexing up to the most dependable solution then I'll do it because I have to lean toward something more dependable at this point. I want to drive this car... I can't put myself in jeopardy of a breakdown constantly.

My suggestion is not to put an external pump on it. They don't last. Yeah there's guys that say otherwise but either they don't drive the car much or they've been lucky. No OEM company uses an external pump for that reason.

Right... That I do know because the OEM style in-tank pumps are designed to be cooled by the gasoline in the tank.

There's no question about whether or not the RobbMC pump is a quality part for me... it's just that now I'm looking for a dual purpose solution so I can upgrade to fuel injection later. It makes no sense for me to buy a carb only solution or that's wasted money.

I just seen this in another post.

It seems that Holley part number 12-307 for a Jeep CJ fuel tank fits an AMC1 type fuel tank.

What is to be done with the electrical pig tail on top of that Holley fuel pump? Does that have to be modified or removed???

No. Two of the wires are for the pump and the other two are for the fuel level. You would hook your sending unit wire to one of them and the other is a ground. If you were to go that route, you would want to switch the low pressure pump that I showed earlier to use with a carb.

Ohhh... Ok... So you're saying if I get the Holley drop in... To switch to the low pressure pump and if/when I go to fuel injection... Then swap out the pump to the higher pressure unit... That sounds pretty easy... 

Any possible hiccups I should be aware of???

Yes that's exactly what I'm saying. Yes it will be easy to swap the pump back to the high pressure for the fuel injection.
The only thing I would say is try and get that sock positioned on the bottom of the tank and use a long sock to get as much coverage as you can.

Ok. I'm glad you told me this. This already sounds like the best solution. 

Thanks!

If you have to go with over the counter mechanical fuel pump the GMB is made in Taiwan and are good. The Delphi and Carter are now made in China and are junk. LRDaum
