Anybody know where to get one of these ?? (the square piece on the top with the plug sticking out of the top). Autozone says they don’t carry it. I tested the harness with the test-mode connectors connected; the harness is supplying 12 volts, but this little guy doesn’t click when connected to the harness or when connected to a different 12 volt source. My problem is that when filling up my gas tank, the pump shuts off after about 3 seconds. I took everything apart and checked the rubber hoses for any blockage. When fueling up, if I hit this part with a wrench after trying to fill up, I hear a “glug glug glug” sound, and then the rest of the tank fills up with no problem. I suspect this part may have failed. My ‘check engine’ light comes on and the code is P1443. I’ve known about the problem for about 6 months, but just haven’t bothered to fix it yet.
