RE: Windshield washerpump ?
When I first started flying RC, my mentor at the time was using a junkyard WW pump from a Chrysler, if I can remember. That damn thing ran and ran like a champ and pumped more glo-fuel than I care to talk about. He has since passed, but I think that pump is still pissin' glo-fuel somewhere.
I have been through 3 pumps in the last 6 years and am ready to make a visit to the local junk yard in search of several WW pumps. One to run, one for backup, and one for back back up.
Good luck in your search.
