thanks for the reply, i will do more serching on the engine lube channels, but i may as well ask before. after looking more i found that i have the piston air pump. i know there is the one tube that has the vaccum, but where and how are the engine lube channels connected to the a/c vaccuum lines? boy, this stuff just keeps getting mor complicated!! i did check the fuel cut off element ( is that what it is called?) the one that is on the fuel pump, and once i hooked up a line that "T's" off the brak booster line it shut right off.
