1978 GMC Washer Tubes and Nozzles
 

I need help on how the windshield washer tubes and nozzles are run. Just bought my 78, pump works fine, but the tubes were all tied up and I have no idea how there were originally run or were the nozzles should be mounted. Thanks

Nozzles go in the louvres on the back of the hood, there should be mounting screw holes if you look closely.

Pump has one inlet and 2 outlets. Intake for the pump has to be at the bottom of the washer bottle. Not much to it. The pump kinda sucks to be honest and unless your trying to keep it stock I would recommend upgrading to an electric pump. Just remember that the switch controls the ground, not the hot side.
