There is a shrader valve that looks exactly like a tire valve by the injectors & fuel lines where there is fuel pressure. A fuel pressure gauge just screws on, and then you can turn on the engine to see what the pressure is. DO NOT clamp any hoses. Try revving the engine and see if the pressure drops, if not see if you can position the gauge so you can close the hood and drive the truck. Do you know how to locate the pressure regulator? What engine does the truck have?
