Jim I just cut the switch out and soldered the two leads together. It had been improperly installed and had heated up, causing a bad connection that eventually dropped to no connection at all. I installed a replacement from NAPA but it was too sensitive to bumps so I just removed it. The circuit runs about six volts as soon as the ignition is turned on, and there was no fuse or anything inside the switch, just a mass and some spring/pressure plate contacts that came loose when jounced, so as long as you don't have a wreck and split your fuel lines, it seems ok to just bypass the switch entirely. see photos:
