The best thing to do, IMHO, is to relocate the pump to the frame, Geno's sells it. Reolcating the pump to the frame makes the pump a "Pusher" pump instead of a "Puller" pump, and it lasts far longer. I have been using the stock Carter pump. When the fuel pressure flickers quickly between 9-12psi, install the spare one you will carry with you.
Many people disagree with me, and run different pumps. But I will stick with that works for me. I have found that NAPA boxed pumps seem to last longer than the ones from Pep Boys, even tho they are all OEM Carter.
YMMV
