Trying to wrap my head around the PET illustrations for the windshield washer pump.. There is an illustration for an electric pump which is what I'll be using, however it seems to only call for "T" pieces - but I believe that's being shown with the early chrome nozzles.
Did maybe early nozzles incorporate a check valve, but the later black one didn't? The illustration for the later black nozzles lists a "T" shaped "valve with valve" (probably a separate check valve, no?). Anyone know what's what here? . |

If you're using a normal bottle from a /4 you will need to add some sort of air-inlet/valve to the cap as the /4 cap valve is meant to keep the spare tire pressure above a certain level.
A stock /4 bottle has no way to let air in if you convert to an electrical pump setup and your pump will burn up trying to suck against a vacuum. I did the cheap and quick hack for my setup, which is to simply drill a small hole in the cap. http://www.914world.com/specs/tech_el_washer.php (IMG:style_emoticons/default/popcorn[1].gif) |
