Okay...with fuel pressure/volume a needed thing to know for proper tuning, someone throw me a bone.

We use a compucar kit and the fuel comes off the schrader valve. We just upgraded to a Walbro 255lph pump. What pressure should I set for our shot (We've been running a 150 shot and have the 175 jets in the toolbox)....? 24lb/hr SVOs on a build 355.

Thanks....

I could start at a baseline of what the old, stock pump was set to, but since the two pumps flow significantly different volumes....:dunno:

 

Stock fuel pressure is what I use....

stock fuel pressure will keep you safe. Compucar may suggest a diffferent setting based on their jetting. I would contact them.
