Sunday I put about 3 gals of gas in and the gauge moved, no leaks so today I put in 5 more gal. of gas, should have about 1/2 tank of gas. But the gauge just move as if it only had the 3 gal. in it. Rocked the truck, beat on the tank but still the same. I don't want to pull the seat to remove the sending unit.

It should. If it doesn't, the float may be contacting the side of the tank. Been there, done that.

Pulled the seat back, removed the sending unit, bent it a little, then checked it with ohm meter all is good . Reinstall the sending unit turned on key and now I have about 1/2 tank of gas just where it should be. Thanks again DADS50. root | | |
