Ok I did the pressure test thing. Hooked an airline up to it with about 18psi and yes I hear a leak coming from around the blower but I'll be damed if I can find it. Got a bottle of soapy wanter to squrt around. Found a small leak at the Cruse controler lever, but there's not much I can do about that unless I replace the entire part. The leak sounds like it's coming from the blower bottem. Too may parts there to get a good view.
