Hey guys, so im kind of at a standstill when it comes to what fuel pump to pick out for my turbo ap1 build. Ive done my research but before i pull the trigger I figured I can just say what I want and dont want... that way i know i dont miss anything and make a $100-200 mistake and get the wrong pump. I know a walbro would flow my goal 450hp but probably be close to maxed out. Thats why Im thinking between the aeromotive stealth 340 and the fullblown 340(which one is easier to install and better performing)

-Must be completely bolt in... no wiring changes, no hanger changes, and prefer no fuel lines changed
-Final goal power will be 450rwhp on 93 oct. But I want enough fueling to support 550rwhp range if I decide to up the boost and go to race gas at some point.
-Safe to run E85
-cost effective but yet high quality

Thanks guys for any help you can offer!

Either pump will work for your needs FB 340 or the aeromotive. They will run E85 and are quiet! Check my build sig

cool, thank you. but do both pumps bolt right in? no wiring or hanger changes necessary...

Both pumps are plug and play, just like a walbro 255.

Okay great. Thank you. Is it necessary to get a new filter like fullblown has as an option on their pump or is it just a waste of a few bucks to not reuse my OEM one

I have roughly the same power goals and went with a FB340 fwiw

I would either reuse oem or get a new oem. I have had trouble with float arm hitting the fuel filter that came with the pump. I will be taking pump out and putting new oem filter on so that my car will read down to zero instead of being empty with 3 bars showing. I reset odometer now and drive to a mileage and then fill up to be safe...just a pain in the ass thats all.

How does thr noise of thr fb340 compare to the aeromotive 340stealth?

I think I am having this issue. I started dropping fuel pressure bad in high rpms the other day when I got to around 3 bars.

To the OP have you considered the walbro 400? You will have to modify the hanger, but I do not see why this would be a problem??
