    Does anyone know if the o-ring seals for the airline connections that feed the air tank pressure gauge on the dash are replaceable? I have an air leak (very audible) coming from the hose that feeds the primary tank gauge behind the dash. We tried trimming the hose a little bit to make sure it wasn't chewed up and tried using a bit of silicone to help it seal. The air is pouring out this AM. Was wondering if anyone has experience with this and to see if the o-rings can be changed. This is a 2001 KW T2000.

    Have never tried changing the o ring. Just replace the pushlock fitting on the back of the gauge would be best.

    This would be on the factory gauge cluster module, are the pushlock fittings able to be replaced? If so, do you unscrew them or how do you get them out?

    On my old truck they just screw on the gauge, should be replaceable on any truck, may be harder to get to on a gauge cluster setup, not sure.
