adjusting Fuel pressure

[syty9933]

i just put on a new adjustable fuel pressure regulator on and have no idea how to set it or what it should be at for 15psi? all i know is you have to take off the vaccum line and adjust it somehow with the gauge

Re: adjusting Fuel pressure

Did you check fp before you removed the stock regulator? IIRC, start the truck, remove vac line and plug it, loosed nut on fpr, adjust fpr with allen wrench to desired psi on gauge, tighten nut, reconnect vac line.


edit: stock fuel pressure is 42 lbs.
