Upgrading fuel pump on returnless system

*KRRZ350* · 02-11-2009, 09:25 AM

What's the deal for 5.5 gen and altima guys who want to run big shots & need to upgrade their fuel-pump. Any options out there? I'm trying to direct an se-r customer in the right direction for running a 150 progressive, and I don't know what you guys think but the stock pump seems sketchy to me in that range, and with the whole in-tank regulator setup that throws a curveball in the mix no?

It should not be a problem.. Drop a walboro in the tank & run a fpr @ the fuel rail.

yeah, i dont know if thats me kevin but i am trying to figure this out.

there is not fuel pump directly for the 05-06 altima, was thinking a 255 but i dont know how to go about wiring it.

i had purchased a dual stage kit but the guy installing it convinced me to go single, also the guys on nissan club. my idea was to run a 50 shot second and a 100 maybe progressively in third.

i just bought the NOS mini two stage progressive controller.
i was reading jimes article on his site earlier about the NX kit that u dont even have to change jets, sounds sweet. now since i just have a single stage i am wondering if i can still spray two stages with my 2 stage controller but i guess i will need two more solenoids. the guy installing this thought i was crazy.

so for now thinking of reordering the two stage conversion
any help with this is appreciated
as for a fuel pump solution

and what is the use of the fuel pressure regulator?
i do have a fuel safety cut off

to run 2 stages you wil need a total of 4 niods and 2 nozzles

and the afpr is used to bring fuel psi back down when you install the walbro

Im pretty sure i remember reading somewhere how aeromotive fpr's work on returnless setups. I think synapse also.

Yes it would work .. have you tried it yet??

havent yet

still havent found a solution, i am thinking of sticking with the stock fuel pump and just going to convert to return style whenever i decide to go down the path of boost
