RE: Windshield washerpump ?
I went back to a big fuel bulb. I had two bad electric ones and could see the writing on the wall. I tried a primer bulb for a snowmobile for a while, but it seemed to suck the fuel out of the gallon can kind of slow. I get about 4 oz. out of a squeeze on the big bulb. I also considered pressurising the fuel can with a cheap (sorry, inexpensive) one way checkvalve type bulb made for blowing air/cleaning. It looks somewhat like the snowmobile primer but has a smaller tip that fits fuel tubing better. It wouldn't have the fuel actually going through it so it may last better. I could see problems with too much pressure, and needing to bleed the pressure.
