Hi all more knowledgabe than I: In several circumstances there is talk of bleeding air from lines such as when a fuel filter is replaced, when the fuel pressure guage is installed, etc. My question is: How exacty is this done? I've heard that you turn the key three times. Is that with the clutch depressed to make the engine turn over or just with the key and no engine turn over? In the instructions for hooking up a fuel line to a guage isoator, the manual talkes about running the lift pump until the fuel flows good without air. How do you do this while you are in your truck turning the key, or cranking the engine? Hope the question makes sense. It will be obvious to some Im sure. thanks Mark
