Ok i just installed my Walbro 255 fuel pump and i am running a B&M regulator. Well it runs fine and everything.. runing at a good 40psi everything seems fine. But now when i turn of my car the fuel pressure drops to 20psi right away and before with the stock fuel pump it would just be at 40psi and slowly go to 0psi. I checked and i dont have any fuel leaks and everything else seems to be working fine. So i was just wondering if the drop from 40psi to 20 psi was normal when you turn the car off with a 255 fuel pump.... thanks

 

anyone?

 

why does it matter, that cant cause any problems

 

well i wouldnt think so. but maybe it says something about the regulator... since i havent really dealt with fuel systems too much i just wanted an oppinion.

 

yeah as long as its not cutting your fuel off, the new pump may just have a quicker shot off time

 

Ok now this is sorta weird. AFter installing the 255 fuel pump and running the same psi i was before it feels a lot slower. man i cant even tell if vtec is kicking in. wtf. it was running better with the stock cx fuel pump...grrr i dont know what the deal is. i mean since the psi is the same shouldnt it be getting the same about of fuel

 

sounds like somethning is cloging it up somewhere, replace your fuel filter latley? Thats #1 then i's say rechect all of the fittings on the pump, at least your not a EF where you have to drop the tank to get the the pump

 

Ya i did change my filter and i am almost positive everything is back together how it should be ...grrrr i'll recheck everything tomorrow..

 

yeah sorry, that kinda weird, take off your filter and flush it, something could have got sucked in when teh new pump was installed, thats about all i can tell ya for now. Keep us updated

 

I think i am going to try a AEM FPR and maybe make sure the fuel pump is sitting in there well.. and my fuel system should be good. I will also fill my gas tanks up cause it is pretty low so maybe its flowing like way to much and the gas can't keep up with it. either way i'll try and figure it out. sorta sad though that it was running better with a stock cx fuel pump. I just need to get my **** tuned.
