I'm looking at converting my buses air supply to an electric under body vehicle mounted compressor that will be able to handle the other applications I would like air for and supply the gearbox.
This compressor would only turn on once the pressure drops which in normal use can be quite a while between pumps on my current set up, and been discussed with a few Routemaster Mechanics.
If anyone is interested in it drop me a email.

***CONDITION***
It works no issue at the moment producing a strong and consistent air supply, but do not know when it was last rebuilt
It has had a new Emergency pressure relief valve fitted
