manual air dump valve leaking like mad

[tombuchanan]

the manual air dump valve on my mc9 crusader 2 leaks a lot of air.  I took it apart and didn't see any seals to replace and don't see any replacement online.  Does anyone have a idea for how to fix this.  I have an extra 4 way pressure valve, can I hook the 2 pressure lines into that and use it instead?  The air dump valve also pulls a cable when used, not sure what it does, but maybe I could use both valves to do the job of the original.

Dump valve for what?

Door?
Toilet?
Tags?
Air tensioner?

Happy coaching!
