I currently have a 255 walbro installed with a return style fuel system.i believe my pump is going bad and would like to swap to the dw300. Does anyone know if the inlets and outlets are the same? And what is needed to wire it up? A shop installed the current fuel setup but I would like to swap my pumps myself.

 

First off y did u put a pos walbro pump in?
The stock pump is better and can flow as much if not more than the walbro can.

I hurd u have to cut the bottom of the canister off to use the walbro pump. Not 100% sure about it.

Wat is the car doing to make u think the pump is bad

 

Running e85. Was told the walbro was best for power lvls im aiming for and thr return style fuel system goig in the car. This was bout 3 years ago. Car stutters randomly and I get a p0171 code. System too lean. And when I get in to high boost it breaks up really bad. I kno I was close to maxing my maf when I got tuned.and idcs were close to maxing as well. During start. Up I let the pump prime the system and it makes a odd clunk noise sometimes in stead of the usual priming sound
