    Hello Masters,

    This is solenoid behind the truck, provides air to multiple things.

    One of them is leaking, did a temporary fix with JB weld, lasted few days.

    Should I changed this particular leaking solenoid which costing $325 plus for a newer one?
    Or can I just bypass it with a fitting?

    - jus curious, how solenoids work differently than a regular fitting?

    Thanks a lot.

    These are to different air circuits in truck aux. like susp dup, air horn, 4x4 fifth wheel slide. you can eliminate said solenoid but they feed from base need to remove all one by one and move end cap one over dont need to use that circuit if unnecessary.
