ok I have a walbro pump and FMU and I've heard that I should remove the FPR. But then I've read stuff about setting the idle fuel pressure. So do I need to get an adjustable fpr to set the fuel pressure or will I be fine without one.

Thanks,
Chris

You need the stock one in there. I had asked a similiar question about using an adjustable FPR w/ a recalibrated FMU and 30lb injectors. I'm not real sure if it will work well and nobody has tried that way. To answer your question, YES you need the stock one to run up to about 8 psi.

thanks. Thats what I thought.
