Dusty,

Thanks for the reply...All new copper lines and hoses hooked up to it, I'm not felling any air moving around it when I put my hand down there. Just wondered if maybe there was a way to lube it up and see if that quiets it...maybe just squirt a little 3 in 1 oil, (or something like it), into the vacuum intake, kind of like I've heard some people do to the wiper moter to lube it. Suggestions?
