I exposed all the air line plumbing and sprayed soapy water onto all of them, even the lines going into the pump and the large pipes going to the two reservoirs under the car, and I cannot find any leaks, either with the pump running or the car turned off.
I tried to look through the other postings on this site, but couldn't find any mention of the problem. Does anyone have any suggestions?
