  • Locating pressure relief valve.

    Hi. I own an 01 f-150 and I can't find the schrader valve that releases the pressure so I can change the fuel filter and clean the injectors. I've seen a couple of youtube videos but my valve is not located where their valves are. Any help? Thanks!

    Welcome to CNGchat!
    The truck should have a quarter-turn fuel shutoff valve which is plumbed between the tanks and the pressure regulator. Turn that while idling the truck until the engine stops. The remaining pressure in the line forward toward the engine will be minimal. That's now most vehicle low-pressure components are prepped for removal/maintenance.
