i just want to know is a walbro 255lph fuel pump ok to run on stock injectors and stock fpr also my injector on 1 on leaking some gas what would make it do that. also is a stock cat not good to use when you have a 4-1 header. this my ef9 that im talkn about so if anyone can help me please do so thank ahead of time.

 

The fuel pump is fine put it in. As for the injector there is a seal at the fuel rail and one in the manifold make sure that there in good shape . If not it can leak . Inspect the injector as well make sure nothings cracked or broken. As for the cat I would leave it unless your running turbo , nitrous or your motor is sick. If its still stock the sound diff isn't worth the 1hp you may get out of it.

 

yo thanks nice to get some in put from someone i know peace out see ya around

if you have a fuel pressure gage and a adjustable fpr.

Your fuel pressure will go up since the pump supplies more fuel. The return orifice in the stock fpr will create a restriction in the fuel return line. If you don't already have one, get an adjustable fpr and gage. I had to replace my b&m fpr with an aem fpr to get decent fuel pressure at idle.
