I've checked the lines from the windshield/headlamp washer pump to the WS wipers and headlights and they are in working order. (My 4-year old son, Nicholas, thought the squirters at the headlamps were great when he got wet as I tested the lines with drinking water with my lungs acting as the pump from each of the four ports at the 1970 pump.) I primed the rubber parts with WD-40 as suggested in an earlier post. When I went to test the pump from the inside switch, I don't seem to get any indication that the piston is moving. Looks like I need to check the piston itself for mechanical integrity as well as the electrical.
My questions are the following: (Mechanical) Where can I get a piston for the washer if it turns out to be defective? Is this piston available through GM/Delco or other distributors? Can I scavenge a piston from other year WSW pumps? (Electrical) What do I test for electrically? I think I read something about this in an old Restorer article. Any tips would be appreciated. Meanwhile, I'll go through some back-issues of The Restorer and try to pull out the info. Thanks.
