Hey everyone this is my first post here, and am looking to get a little insight on this annoying issue. The fuel gauge reads full when i have a full tank and will work until i use about a gollon of fuel then the gauge will go to completely empty and ding. it then will jump back up to completely full and then go too empty again. Any ideas? I would rather not replace the fuel sending unit..... but if thats what it takes.

Thanks for the help

Thats what its going to take

 

i had the same isue i bought a leveling kit, its a replacement float arm and plug pull the sending unit and its prety starit forward, coast me 60 bux at the local dealer.. ive also heard of people just having a bad connection at the plug try cleaning the plug first to see if anything happens! if not id do the leaviling kit sending units coast alot of $$$$$$!

hope this helps

 

So don't mean to bum off ur thread but mine is staying at full till the last 5 gallonsthen it drops down to like a 3/4 any ideas? I heard of a mod for this where u can fix it ur self but can't find it again. Any ideas what is causing this in there?
