This FD0002 Delphi pump any good ? http://www.summitracing.com/parts/DFP-FD0002/ Says its OEM application for a whole bunch of stuff but I don't recall them on any of these cars that I've seen. http://www.summitracing.com/parts/DFP-FD0002/Application/?prefilter=1
that is just a inline universal pump your loacal parts store should carry them also maybe a different brand.i used one on my 85 chevy pick up with a stock 350 and it worked fine you may need a pressure regulator with it.
Regulator or ... http://www.jalopyjournal.com/forum/showthread.php?p=8074987#post8074987 I hear it works well. Idk but I will shortly
let me no how this works out.i have done alot of fuel systems and never did one like this.so insted of using a regulator you will use a filter with a return to bleed of extra fuel pressure?or am i way off.
That's the idea. Also in theory it is supposed to eliminate all vapor lock issues because of the circulation. That was Pontiacs reasoning behind it anyway.
Are you using it with carburetion or EFI? 20 psi is overkill for a carburetor. We use pumps like these on forklifts and manlifts. Put a filter between the tank and pump. Any trash in the tank will foul the check valves in the pump.
No efi, Summit has that rated at 20 but Delphi has it at 8.5 but cross check the OEM applications Delphi has fd0003 rated at 4.5 and those applications are all foreign 2 liter or less
Back in the day we ran an inline electric pump on both our race cars... An electric pump and a cool can and vapor lock is not a problem...
OK, this fuel system uses that pump, 3/8 feed line to the filter linked above, 3/8 feed line to carb from filter. 1/4" return line to tank. Its a Steady 4 psi at carb inlet and that's at full volume. Closing off the return line gives 9 psi at the carb inlet. A variable restriction in tge return line could net you any pressure between those two AT FULL VOLUME of the pump. I have been trying to find a vacuum sourced regulator put I probably won't need it.
