Hello; Okay, I understand now, thanks for clearing that up for me. A few of the fellows I fly with have had great success with a fuel pump off a Mazda car, or any automotive electric fuel pump. One fellow (Elwood) has had his since the late eighties with no problems. I tried a windshield washer pump once, but it didn't last very long. I bought 3 or 4 12 volt pumps too, but they all seemed to start leaking after about a half of a season, so I gave up on them (thunder tiger) and went to the hand cranked one.
