<BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content">I have a freightliner chasis diesel pusher and it has a Gast vacuum pump mounted on the frame in front of the engine. Someone wired (rigged) a toggle switch to the pump and it was off when I purchased the RV. The pumps bearings are shot though it runs a little when the switch is turned on. Does this pump exist soley for the cruise control or does it tie into anything else? </div></BLOCKQUOTE>
