leojharris Posted June 8, 2006 Share Posted June 8, 2006 hi . i have a screwed up gas gauge. after a fill up (and $55 bucks or so), the gas gauge reads half tank after just 50 miles of travel. the last half of the gauge dwindles away over the remaining 240 miles or so that i tend to get out of a tank. when i first got the truck and after the first fill up tihs really freaked me out. anyway, it's a livable situation but would love to find out what i might do to make it register or progress along it's course of showing diminishing gas reserves in a more regular and accurate fashion. any tips? thanks. joel.

jj big shoe Posted June 8, 2006 Share Posted June 8, 2006 It reads full and then drops to half tank or never reads full? I'd pull the fuel pump assembly and check the float. It might be binding or have a crack in it allowing gas to get inside it and sink it some. If that's not it you might have some voltage problem from the sending unit or something.

derogate Posted June 8, 2006 Share Posted June 8, 2006 mine did exact same thing. I just got used to it. The last 1/3rd of the tank actually represented the majority of my tank. Not sure why it does it, but I just learned to deal with it... besides, its not really that big of an inconvenience, if anything it'll help your fuel pump, cause u'll be filling the tank more often (thinking its low and whatnot).

GrimGreg Posted June 8, 2006 Share Posted June 8, 2006 you might have some voltage problem from the sending unit or something. That would be my guess. I found a short in one of my wires, mine had been reading 1/4 tank below actual. Link to comment Share on other sites More sharing options...
