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

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.
