Fuel Gauge Help!

Contact the guy above ya LOL

But before you do that, unless you already did, I'd sure go clear through the wiring, from front to back, and make sure you have

1 Solid 12V to the voltage limiter (Make a long jumper, run from battery stud on start relay to your meter, the other meter probe on the IGN feed to the limiter) and check voltage drop

2 Make sure you have a good quality limiter. ALSO make sure the "socket" for the limiter is actually making contact with the PC board. Mine was NOT and I had to solder short jumpers from the brass contact fingers to the board

Make sure the harness connector pins to the board are tight and clean

Make sure the gauge studs are making contact. Loosen/ tighten the nuts several times to "scrub the connections" You can also check with a meter from the studs to the board for both resistance and voltage drop.

3 With the sender confirmed to be at the listed "full" resistance, if the gauge is wrong, then it's the gauge
