air system wn40

[RWW]

I concur that an air leak can prevent it from airing up. Been there, done that.

Jamie,
Fix that air leak, and I bet all will be fine. I had one of the two air dump control valves leaking slightly...the coach would not air up using the on-board compressor. It would build pressure using both the on-board and the engine compressor (engine running of course). I replace the leaking valve and the on-board compressor is again doing its job.

Jamie,



My 91 on-board electric air pump builds up to 90psi.



I would assume that the 90 model should be similar, but perhaps someone with a 90 model will respond. I know Steve Gureasko has a 90 but he is traveling today, headed home from the LSB rally, and may not see your message for a while.



Which air pump do you have that is built in? Perhaps there is a rebuild kit available. Sounds like it is time for a rebuild.
