HH56. U currently have a PI pump and electric wipers????

I'm running the Olds conversion oil pump ergo no vac pump. Retained the factory original vac wiper motor. The PROBLEM is pulling long hills using only engine vacuum. The wipers will stop. Short hills not a significant problem.

My recommendation is stay with the electric wipers if that is what u have. OR, go with an electric vacuum pump or a constant drive vacuum pump from a diesle and run it off of the fan belt.
