I just installed a B&M FPR and B&M fuel guage but im unsure at what pressure to set it at. Everything on the motor is stock (injectors, ect..)

What should fuel pressure to when the motor is at warm idle? Id like to get the best performance/fuel economy ratio.
 
FPR's are useless. if you're stock, put your stock one back on and sell the one you bought.

if you're modified to the point where you need more fuel, get larnger injectors.

pressure is not volume.

i wouldn't even consider running a FPR until you have 400 hp, and need to tweak your pressu resome keep the large injectors pressureized at all times.
 
Well.. I already cut my stock regulator to install the B&M but now I have no idea what to run the FPR at now :(

Whats a B18C1 run at or are all B series the same? 38 idle, 43 wot
 
So all I have to do is let the car warm up to normal temp, then adjust the FPR to 38psi while having it connected to the vacume line?

Someone told me to have it set to 48-50psi at idle (norm temp).... is this wrong?
