How big of a line is needed? I have been using the line that came with the booster. But, it was necked down at the manifold to the original wiper hook up.
I just completed a trip to Home Depot and got some brass fittings. I now have 3/8"s coming out of the manifold and supplying the booster, with a T that necks down to a 1/4 for the wipers.
