Need help guys
I need to know where the fuel pressure regulator is in my engine bay? and how would i check it if it was faulty or not. Also what type of pressure gauge do i need to check fuel rail pressure? thanks

The pressure regulator is on the fuel rail and has a vacuum line ran to it. With the truck running pull the vacuum line from the regulator and cap it with your finger quickly. If the idle picks up the regulator should be fine. You need a fuel pressure gauge for fuel injected engines, a gauge for carbureted won't work.

ok good to know. But she is not running, shes just stuppering. My next question is are there high pressure fittings attachiing the regulator or do those two bolts come off and swapped out?
