Brent asks:
How do you change the fuel pressure regulator on a 1997 Safari? (4.3 Vortec)
Brent, I don’t have that specific motors manual. I would suggest you look at the fuel rail on top of the manifold and look for the regulator which would have a fuel relief line going back to the fuel tank acting as the pressure relief line. If your fuel pressure is low you may have a fuel pump going out or a fuel filter that is becoming clogged up.
Don’t forget to disconnect your battery and remember the fuel rail will have pressure on it when you disconnect the fuel regulator so watch your eyes when the gasoline sprays out.
Good luck and Drive Safe!!
