What fuel pump to get

[gamingguru]

I am getting a PTE 50 trim in a coulple of days and wonder what fuel pump I should get to go with it. I was planning on getting a Walboro 255HP and a Aeromotive AFPR, but since this project is already over budget I was wondering if a 190lph pump would be able to flow enough fuel to my 650cc injectors to let me boost up to around 21-23 psi.

I wouldn't think so....I would think the 190lph pump would be for like 14b-small 16g. I think you may starve your injectors. I know that extremepsi has an overstock of 255lph pumps on eBay, I got mine for like $70+shipping.

Are you using an AFPR, I don't see one in your mods list.

Nope, I feel they it is pointless to use right now since I am not not even near 20psi.

190's flow a lot more than people think. Personally, though, w/a 50 trim I'd invest in the 255 and a regulator. I run a 190 w/550's and I'm on a B16G at 20lbs. I'm still pig rich. But the 50 trim is a bigger turbo, so I think I'd opt for the safety of the bigger pump.

I would go with the 255 and the regulator. It allows more elbow room for system upgrade or alteration.

Do you know what your fuel pressure is with that pump installed?? I think that's why he was asking. Many times (not all the time) after installing a Walbro 255, your fuel pressure can sky rocket. Thats a big reason people use AFPR's. My pressure jumped to 62 w/o one. I had to get one to crank it back down to stock.

Yep, that is what I wanted to know. Thanks for answering all my questions.

Can't wait till I'm boostin again.

About that mine runs fine and fuel pressure is fine....Only thing wrong is that it's louder then normal but that's obvious and that's not really a problem.

when it comes to fuel systems i would error on the side of redundancy. so if your getting an afpr anyway, just get the 255
