my 2000 gmc the gas gauge goes from full to empty every few minutes and when it goes to empty of course the low fuel light comes on any help would be great.

that might have something to do with your sending unit in the tank?

what do you think i would have to do to fix the problem with the gauge any ideas

96dieselguy

ground wire on the sending unit, the sending unit its self, the wire harness, or the gauge might be junk. with out being there to look at it i cant really tell you what it might be.

i hope this some what helps

is there any way possible having your spare tire mounted cause the fuel gauge to malfunction

i wouldn't think so, why do you think that it would?
