Fuel gauge, wiring, sender issue.

I don't know if its gauge, wiring, or the sender, but... The fuel gauge in my truck only works if the tank is half empty. If the tank is full the gauge reads empty, until the tank gets down to about half, then it reads right. I'll probably swap the sender here soon, but was wondering if anyone else had this problem, or any input.

it happens to all our trucks at some point...read this its an easy fix

Thanks a lot man!

no problem

That'll save me some money... won't be a hassle either, because I'll be swapping beds here soon anyway.

even with the bed on these tanks are easy to take out

I'll pulled a few tanks... one in my wagon on my steep driveway the night before a show because I drug threw it... not fun. And my 73 Chevy tank about half full cause it got smashed... not fun either. Thanks for the heads up though!

Easist Way:

Disconnect cable release and the two rubber hoses at the gas fill assembly (loosen and raise bed slightly [see below] to remove the larger one).
Remove the three 17mm-head bolts on the passenger side bed frame.
Loosen the corresponding bolts on the driver's side, about about 2/3 of the way. Use a 16 inch 2 x 4 on a floor jack to lift up the passenger side of the bed Tighten the jack, and up tilts the bed. I used a 1/4 inch drive ratchet, with 1/4 inch socket and a #2 Phillips bit (and two hands to hold it straight). All mine loosened, but maybe because I'm in Arizona there was no rust; I replaced with 7mm head hex head screws (4mm thread x 8mm long, with a wavy washer). To line up the bed so I could get the three 17mm head bolts back in on the passenger side, the bed needed to be jacked up a little, then I could use my weight to shift the bed a little from one side to the other.

ok guys so i have the same problem as the rest of you my fuel gauge doesnt work... so i have my box off and im looking at the sending unit and the screws are pretty rusty ive sprayed them with penetrating lube but what happens if i cant get them out ? drill them ?? ive already got the new hex head screws to replace them!

4 out of the 8 stripped cause they were so rusty i dont know if i should drill them cause i dont want to get all those metal shavings in my tank any helpful info would be greatly appriciated
thanks
