A couple of years back my mechanic bypassed the VRO on my '88 GT 150 when the pump started to fail. I've regretted the decision and want to replace the pump and undo his "undo" of the operation. :/
The original P/N for the VRO pump assembly is 174307. I can't seem to find the part anywhere and was hoping that someone can direct me to finding the "supercede" part numbers.
