my gas gauge

ok so i own a '96 Tahoe, great truck, big fan of OBS trucks and all but i have the same problem almost any other Chevy OBS truck has, the damned gas gauge. I swear thats like the only one i ever have trouble with, I already had the gauge cluster replaced, tried the replacing the fuse, and now i might just check the wiring cause im tried of gambling how much gas i have left.
