    Need help, Stupid fuel gauge

    Im going to Carlisle PA, next weekend for a car show and its about 8 hours away, back in February I had to pull the dash to do the heater core, and when i put everything back together my dome lights and fuel gauges wouldnt turn on but im not worried about the dome lights but primarily the fuel gauge. I checked the ground on the sending unit and it wasnt very tight, and found a new ground and tightened it, I got a little frustrated and decided to buy a gauge. Wired it all correctly from what i know, and something really odd is happening. When i shut the truck off is drops down to E like normal, but when i turn it on it goes directly to the full mark, AND I KNOW IT IS NOT FULL (just saying) but ill jack the front of the truck up while the gauges is on and when i drop it itll shake towards 3/4 of a tank and lower but when its level itll go back to the full mark, soo i was thought wtf ill go put gas in it to see if its reversed or something, well the fuel gauges continues to move past the full mark as i put gas in it, Do you guys think its the Gauge, the sender wire, the ground, the sending unit. Idk im effin confused and i dont have alot of time. Anybodies opinion will be greatly appreciated.

    Soo does anyone know if i were to pull the cluster and put any voltage to the fuel gauge if it should move, and if so how much voltage if anyone knows.

    sounds like you got a gauge that is set up for the wrong number of OHMS

    That's what I thought too but my gauge will read from 0-90 ohms which what the fuel sender reads if I'm not mistaken, I wonder if it was packaged wrong or something, but do you know if I could jump my factory gauge to see if it'll register in anyway?
