Tom:
That's very interesting and maybe you have hit on the answer. I now have
the electric pump installed behind the dash, slightly above where the
old plunger, and now electric switch for the pump, comes through the
dash. So now the pump is "pulling" the water all the way from the bottle
to behind the dash and the pump, then up to the washer jets.
Maybe I need to re-install the pump in the engine compartment next to
the washer bottle, so it "pushes" the water through the hose from there.
I wonder if the electric pump itself has a "check valve" of some sort in
it to keep water from flowing backwards through it when it's off. That
wouldn't do any good in its present location.
The next question would be should I punch a hole in the bottom of the
washer bottle and run a tube from there to the pump (maybe installed
below the bottle)? That could feed the water by gravity to the pump, and
the pump would then "push" the water through the line up to the jets.
This way the pump wouldn't be deprived of water on start up so even if
it still took a few seconds to get the water through the jets, the pump
wouldn't be running dry during that time. I've got an extra washer
bottle I can use to experiment with so I'm OK to try it.
