Fuel Pump Selection
Wondering on weather to get the TPI fuel pump, a Walbro 190 or a Walbro 255.
The pump is going to be supplying a mild 350 TBI with vortec heads, GMPP aluminium intake, full exhaust, open element, mild flat tappet comp cam, and 80# injectors at ~18psi. What pump should I use?

Re: Fuel Pump Selection
I've heard the walbro has quality issues, and that the AC delco TPI pump works well.

Re: Fuel Pump Selection
I run the Walbro 255 and it works great. I have heard that the Walbro 190 is a better choice after I did mine. From what I understood the Walbro 255 is a bit too much.
