Fuel Pump
 

I was wondering what would be a good external fuel pump to run on my 12A. Its basically stock for the most part. I run in ITA. I have tried a couple other ones. but still having problems with pressure and so on. Maybe its something else. I have tried Three different regulators. No idea's as of right now. I have a fuel cell mounted in the trunk with 6an lines running all the way up to the regulator in the engine compartment etc. Also whats a good fuel pressure to run. Any help would be great. Also if anyone has any pics of there setup or anything would also help. Thanks Brian

more info on your engine please

Its pretty much stock. Its an 85 12a with header and full exhaust. Im running a stock carb without all of the emissons etc. What else would you like to know?

Carter or Mallory 70-72 gph pump or a Holley pump of similiar size. What pumps and regulators have you run and at what fuel pressure. The stock Nikki likes 2.5-3.5 psi.

2 of the fuel pumps i have tried are i beleive are an old carter. Not to sure on the volume are mass. The number on the pumps are (12V 4594) The other one i have tried just for the hell of it was a Mr gasket (12V 4 2S) it was a universal. which was a low pressure pump. The first two regulators i have tried where the holleys 1-4psi and then 4.5-9psi because i was never sure on what pressure to run at first. But with those two regulators i could never get a solid fuel pressure. It has always given me a different fuel pressure on the gauge. Then i picked up a clamp lock regulator which has a solid pressue know matter what. Fuel pressures i have tried have been any where from 1-6 psi and nothing is working. i have tried like you said 2.5 to 3.5 and its still something is not right.
