Problems with air dumping

[Howard O. Truitt]

Glenn,
Check with Stephen Birtles he now produces the Dupree line of dump valves.
Stephen said he would have a booth at the RIV and RATS rallies and would have
parts for repairs. I found that using mine regularly has helped with it
sticking.

Bob,

Can you provide the part number of the valve(s) you used to replace
the orginal equipment? I also have a randomly sticking dump valve.

Thanks,
