I seriously doubt that you can repair it without dropping the tank, especially on an AMX

I replaced the sending unit in my 69 AMX without dropping the tank. It wasn't easy, but I did it.

You must have a hole in your trunk floor? Confused

Mustang Production:

1964      121,538
1965      559,451
1966     607,568
1967     472,121
1968     317,404
1969      299,824
1970      190,727

AMX production:
1968        6,725
1969        8,293
1970        4,116

Add in Javelins and you'll be close to 1/2 of the 65 mustang production numbers. I don't know what the interchange is on Mustang sending units, but the economy of scale created by the number of cars on the road justifies the price difference. ]]> Tue, 01 Mar 2011 14:02:13 +0000 http://theamcforum.com/forum/1969-amx-fuel-sending-unit_topic27148_post249984.html#249984 1969 AMX Fuel Sending Unit : 70 Donohue 390 wrote: citrusz... http://theamcforum.com/forum/1969-amx-fuel-sending-unit_topic27148_post249976.html#249976 Author: AMX09652

what car do you need it for? I have quite a few NOS ones for hornets and gremmies.

A new sending unit for a vintage Mustang can easily be had for $20. I know there are a lot more mustangs than AMX/Javelins, but $20 verses $100 seems like a big difference. The Mustang unit looks similar to the AMX unit but I agree that it might be more trouble than its worth to try and adapt one to the other. I just wanted to check to see if anyone had tried. I adapted an aftermarket sending unit on my 59 Jeep, but admittedly its a pretty simple tank and unit.

My unit is a replacement by a PO. The mount that holds the rheostat wire broke although the wire is still intact. I thought about trying to repair it, but I'm not sure how and I'm not sure it would be a long term fix.

I guess I'll bite the bullet and pay the price for owning an oddball.

$100 is too high? $20 part?
Maybe you are correct since you can buy them for $80 on eBay now and then.
(but buy from a vendor - support the AMC vendors and they'll guarantee the stuff)
Have you bought any for OTHER classic cars lately? Not exactly cheap.
LOL - like pmm says, you wanna make only a couple hundred of them with your own money and hope 200 folks need them?
citrusz is right, but since it takes only minutes to drop a tank, I just drop the dam thing and be done with it, rather than fighting a new tight o-ring and retainer up under the car. I can then check the tank, clean it if needed, etc.
I can drop a gas tank without jacking the car up, and it takes maybe 10-15 minutes.
Spray down the nuts/strap bolts and let them soak. Enjoy a beer or two.
Crawl under car, unplug sender, unbolt ground from chassis, loosen two nuts, drop tank to chest/stomach, slide out from under car, set tank aside.
(maybe those snap-on fuel tank nut sockets are what makes it so easy??)

To answer your question about swapping in something from another car, I would be very surprised if you could find a direct swap. Electrically, I think Ford is the same or similar but the donor would need to also have the exact same size and shape tank.

FWIW, $100 isn't much for a sending unit. I have a 78 El Camino that needs one and last time I looked (about 5 years ago), it was close to $250.

They can be fixed (they are very simple devices) but unless you can do it yourself, it will likely cost a lot more than $100. The sending unit is just a tube with a rheostat and a float attached. It may turn out to be a simple problem like a bad float or dirty rheostat but if the thing is a big rusty mess, it may not be in good enough physical condition to fix.

However you end up fixing it, you need to replace the in-tank filter, o-ring (goes between the sending unit and tank), and replace the short section of fuel hose by the tank.

Is fixing it out of the question? If so, you don't have much choice. The good news is you don't have to drop the tank to change it. I took mine out, repair it. Lasted a year, then I went for the new one. It all comes down to money and time. Only you know which you have more of. ]]> Mon, 28 Feb 2011 18:44:49 +0000 http://theamcforum.com/forum/1969-amx-fuel-sending-unit_topic27148_post249711.html#249711
