so slightly on the same subject, walbro 255 or oem pump for a surge tank setup? i heard both the arguments from close friends. the oem pump is a oem pump and will outlast the aftermarket and can support a surge tank on e85 no problem and also the flip side is that the walbro flows more and would be a new pump and be a better choice. im torn

 

I would say use whichever you have on hand. If you have both, I would use the OEM one because it does not need to flow an extreme amount of fuel.

 

I bought a walbro 255 for my old WRX that I had an STI turbo running on E85. It died after about 8 months and also was stupidly loud in my opinion. The "warranty" Walbro has costs 50 bucks to have them inspect it if it fails to determine if it is warranty or not... When I saw that, I said screw them and bought a deatchwerks 255lph pump. They use a scroll type pump, which is silent and never had an issue with it. Was a great time changing my fuel pump out in the parking lot at work though!

 

 

255 is to small for e85 and it's not made of stainless steel.

Walbro 450 is your answer

 

It's probably going on 4 or 5 years. I still talk to the guy that bought it occasionally. He's been running E85 still.
