I disassembled my pump and checked the diaphragm, the rubber looked really good, I replaced the cork seal for what looks like the overflow tank, this is not the original kind of pump with the unscrew-able filter. The filter is inside the well for the intake seal and it was perfectly clean as there is an inline filter. The cork seal was old and had a break along where the tightening screw goes in but around the perimeter it was good. I created a new on by oiling a new piece of cork to make it moist and more pliant.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I found that the diaphragm needs to be screwed in enough so that the contacts can be enabled by the magnet, too loose a diaphragm and the pump won’t pump especially by the time the voltage goes all the way through the wiring.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>As it is pumping, it provides too little vacuum when felt by finger test and clearly not enough to suck gas. I believe my i/o seals are set up incorrectly and intact. I have no way to know if my gaps and diaphragm as adjusted correctly as I don’t have the indicated test equipment. In addition, the manual is for a different pump.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I would think as long as the piston is going up and down I should at least get a stronger vacuum. What do I do?
