Two Walbro 255 Lph Pumps
Just got back from the dyno for my first pull. Fuel pressure fell to 33 psi @
4848rpm twin turbo set up made 447 rwhp with 15 psi boost. AFR went to
12.2. Realized that only one of my fuel pumps are working. I found the fuse blown
and the second pump is shorted. Is this comon for a walbro 255 pump?
