1991 Ford Explorer 6 cyl Four Wheel Drive Automatic 212, 00 miles
I've owned and immaculately maintained this truck since 1992. Replaced just about everything except the drive tran and fuel pump. She's a great ol' gal and my OBX beach vehicle and I plan on keeping her in the sand for another 16 years GW. The fuel gage stopped working. Didn't float around, just stayed on empty. Tank was full. I dropped the tank & changed out the pump/sending unit. It didn't fix the problem. The gage was now registering fuel, just not the correct amt. I got a new pump/sending unit & repeated this process. This time I ohm bench tested the NAPA OEM Carter pump unit and it was perfect (16 w/float down, 160 w/float up) Reinstalled. Still doesn't work properly. Again, the gas registers, but I filled it and did not get above 1/2 tank. Today it registers 3/4. I checked the ohms at the connector. Should be close to 160, but it read 2.4 ohms @ 200. The first replacement unit registered 4.1 ohms w/float down. Is something shorting out the sending units, or could it be I damaged the sending units knocking the retaining ring back on top of the tank? I was pretty gentle. Pumps have worked fine, even the original was not acting up. Thanks!
