    Hi everyone. i'm new to the forum. I thought this would be as good a place as any to help id this valve that is leaking on Dad's truck. it is an 89 KW T800. This valve comes out of the tank and i believe the air line goes back to the ride height valve above the rear axles. so what would this be and where would i get a new one?

    Hi, just take it off and go to the closest dealers, they should have it or at least order it.

    That is a pressure protection valve, meant to stop air flow if a line breaks. For the suspension they are normally a 90 psi rating, meaning it will open about 90 psi and close below that, to save air for the braking system.
