Clear line on the return should be enough to check for air in the systemFound some at our local part store. Is it worth also putting a clear line from the ffm to the injector pump? Or is the return line enough?
I'd like to hear a better description of the "rough running". Is it like a miss, any smoke at all? Does it sound like a miss out the exhaust or intake, or is this something you feel in the truck? Maybe it happens at certain vehicle speeds? Happens at certain engine rpm?
