just picked up a 97 xlt explorer, gas gauge issue

[mateofff]

howdy! nice to meet you guys.
i just purchased a 97 explorer 4wd, all is good but the gas gauge, it always reads full, i replaced the sender unit, checked wiring and did the anti slosh module bypass, but still reads full.

ps, when i did the anti slosh module bypass it read half tank but after a couple of hours it went full tank again

Welcome to the forum.

I found this fix for the same problem. No way to know for sure if that is the issue your Explorer has until you check it out though.

"Just fixed mine!!!! Always read full.
First thing I did was pull out the guage and check the voltage at the connectors. Top was a ground, left was 12 volts, and right before it was fixed was two volts. I then pulled the guage panel out took out all guages and bulbs and carfully disconnected the clips. I then followed the trails along the ribbon and checked continuity on each end and found one that was cracked. I carefully sodered a wire around the break and it works."
