I agree. I’m keeping the vacuum wipers on my car, so I will have a fuel pump either way (it just may not be pumping fuel!).
The in tank setup is a nice idea. I had a Holley kit in my Pontiac (new tank with their pump and sender). The gage wasn’t accurate and I had issues with less than 1/4 tank of fuel. And that tank had a baffle in it. I’m a bit nervous with no baffle in the stock tank. But maybe things improved in the last 3 years. I’m not sure which way to go yet.

On that setup I show, the sock sets right in the lowest part of the tank and is pretty long so it's positioned to run with that bend (low point) in the tank. Neither one of us has ever had an issue with fuel starvation on a hard corner like a sweeping on/off ramp. I generally don't let my tank get to much below a quarter but even at that level I've not had a problem. The reservoir can mimics what the OEM's have so the pump is always in fuel to keep it quieter and cool by the return line running into it. I'm able to keep my stock sending unit plus I put an access hole in my trunk floor so I can replace the pump without dropping the tank or even getting under the car. I can replace that pump in an autoparts store parking lot if I should ever have to. Just something to think about if you drive your car much.  Oh and the pump is a popular over the counter pump so nothing special that would have to be special ordered. |

My pump (E2000) was $20 and $10 in fuel fittings. Brackets were less than $10 from Home Depot. It is pretty much silent. I hear the whoosh of fuel through my fuel lines more than I hear my fuel pump.

I bought a 57 Belair a year ago. It has a high perf 350v8 with headers and FiTech 30003 and a Aeroflow 650hp frame mounted electric fuel pump (Aeroflow AF49-1014). No issues with fuel pump....yet. The previous owner had the car for more than four years. The electric fuel pump is mounted by the door outside the frame away from the exhaust.
I have owned cars that had gas vaporization issues especially during the summer months. Problem was the inline electric fuel pump or fuel line was too close to a heat source and vapor lock occurred causing the engine to die from fuel starvation.
On my late model Silverado truck I recently replaced the in-tank fuel pump. The counter guy at the GM Dealership parts counter suggested I never allow the fuel tank to get below 1/4 tank because the fuel pump will get hot and live a short life and stop working. He said the gasoline keeps the fuel pump from overheating. |

Reviving an older thread, I am looking into what options are available for in tank high output EFI fuel pump for my 70 Javelin, anyone know if either of the Holley in tank kits listed on the link for 73 - 87 Jeep CJ kit would fit the stock sending unit opening on a 70 Javelin? I can modify the assembly as needed. J

Hello there,
I put this in my Spirit AMX and it works great. Yes I had to drill a hole in the tank, pretty easy. I did an access hole with door in the floor should I need to replace the pump. I also ran the LS style fuel filter with self regulated return line. I also used the PTFE fuel line so that there would be no gas smell.

What I would like is a high performance fuel pump that has a stock fuel tank setup, the link posted by Roger 6PacBee for Holley has muscle car EFI sending unit modules that show two listings for fuel pump kits 12-307 255 LPH and 12-377 305 LPH for 73 - 86 Jeep CJ models. If the Jeeps use the same size sending unit hanger (round plate, seal and locking ring) as AMC cars then the Holly kits could be fitted to my 70 Javelin tank and possibly other AMC models of that era. I contacted a Holley tech yesterday Taylor he did some checking to find out if the sending unit is the same, Holley doesn't have the hanger specifications readily on file however if I buy a Jeep CJ kit with the help of Taylor and it can't be fitted he can help me return the kit if it's unchanged. Anyone know the fuel sending unit hanger seal plate diameter for 73 - 86 Jeep CJ's? I was just reading the specs on the Holley kit there is no need for a return fuel line, I believe all I would have to do is remove the Pro-Flow fuel rail regulator and plug the rail on the far end.
"Fuel pressure is internally regulated to 58 psi eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator - no separate return line is required because this module returns excess fuel right inside the tank!"

By Jove, I think you may have found a solution.

Any idea what the resistance on the fuel sending unit is? Think our early cars are 73-0 Ohms. Looks like a great alternative to cutting the tank if it will work. I've got a Pro-FLow and aftermarket tank for my 69 AMX, haven't purchased a pump yet. Bob tufcj
