Hey,

I just installed my Walbro 255lph HP fuel pump, and now my car seems very sluggish. Did I get some dirt in the tank? Is it running too rich? Or maybe the ECU is overcompensating and its running lean? Please help, I will be installing my S/C within a week, and I really would like to know what the hell is goin on.

Thanks in advance..

Wanna race! JK. I have no clue whats up with that, did you reset your ecu? That may make a difference?

 

Hmm, good idea....I'll try that today....

 

ok you know i just put mine in and it RUNS GREAT, nothing has changed at all except i am running a little rich, but oh well. I think you have a kink in the funny double U shaped hose that goes from the pump to the access plate. it's a common thing and it's BAD, you have to leave the hose's not tightened then put the cover down, let them twist into place then move it a little and tighten them. I'd bet this is what it is, unless you messed something up with the siphon bad. try changing the fuel filter. i'm doing mine on tuesday.
