I have been a member for a while now but this is my first post. I am kindof quiet and have always been able to search for what I needed until now. I have searched many threads and not found just what I wanted. I hope you guys can help me on this one as much as you have in the past.

My TPI 355 is in a 1990 Jeep Wrangler that I built my own frame and suspension and is mostly buggy and not a Jeep. I use it for trail rides and comp. rock crawling. I had a throttle body on before and it just did not give me the performance I was looking to spin the 42 inch swampers I have. The fuel tank I run is a fuel cell and I have mounted the fuel pump under it so it is has gravity feed.

My problem is the pump at idle shows on the rail guage to be at 40psi but when I rev it up it will drop to at times as low as 32 or 33 psi. I know the injectors are larger if that makes any differance in psi. I dont remember what size they are but it seems like they are 32lbs injectors. i know they are ford motorsport injectors from Affordable Fuel Injection and were matched flowed.

Back to my original question... What fuel pump (Electric In-line) can I buy over the counter from the parts store. I am looking for a brand with part number or the application that I can tell the parts guy. Becuase of the nature of my sport I will need something fairly easy to buy because if I have one go bad I have to leave the rig in the woods on the trail and go to town to buy a new one to get it running again. Its not as easy as having one die on the road and call a wrecker!!!

Again I hope you guys can help me with this one, Thank you in advance...

look for one from a 89-90 5.0 ford van they have a inline pusher pump not sure of the part number but would be easy to replace in a pinch has a clamp on one side and that plastic clip for the line one the other i was gonna use one of those for my nitrous setup hope this helps

 

Thats the pump I having trouble with. That is the universal pump of choice on my 4x4 site. (Pirate4x4)

Thanks though, Anything else?

i thought you had a in the tank pump too

 

No I run an aluminum cell and the pump sets just below it (3 inches of hose) and is gravity feed.
