I bought a French fuel pump because I like priming levers on pumps. I thought I could use the bottom section of the pump with the stock top half. The bolt circle is slightly smaller so that idea went out the window. Since I have it and my pump needs rebuild I may as well use it.


PO modified fuel line. I had to get some longer hose. Works great, no leaks but, press is 4 PSI. I need to drop it.

 

Good job! I don't know how well Ford Nuts seal under pressure, sounds like they must work OK.

4 psi at idle won't hurt it if you have a good needle and seat. It likely drops at higher RPM.

 

Thanks Ross, I wasn't sure if anybody would be interested in this. Just thought I'd post it in case somebody had the same idea I had.

The Ford nuts were a pain in the a$$ to get to seal. The 4 PSI ended up being a problem at idle. I have one of the new style float valves. I can see the top gasket getting wet and it started to blubber a bit at idle.

I ordered a Holley low pressure regulator and I'll probably change to flared fittings. What do you think, set it to 2 PSI ?

 

2 to 2.5 should be fine, but I'd ditch the needle and seat regardless. When you shut down on a hot day, the pressure jumps up in the line to the carb, you don't want it to push past the needle and flood the engine. If you need a set I have a bunch of used all-brass that I don't need.

I'm a big fan of putting a metal-can filter between the pump and carb. If you do that, you could use hose nipples on the carb and pump and use short lengths of (ethanol resistant) hose.

 

I'll take you up on the needle and seat offer. I'll PM you my info. Thanks!
