Wassup Guys I have a 1992 LS400. Havent had any issues from my fuel gauge until when I filled the car up Sunday evening. It worked probably up until Tuesday and has since stayed in the same position at 3/4 tank. I've read a few different remedies on here to what causes this, just looking for outside opinions on where I should start first. I'm assuming the caps on the cluster?
Thanks,
Ace

 

Update: I was driving to work this morning and hit a hard bump(coilovers on stiff) and the needle started working correctly for a few seconds. I'm assuming could be a loose ground now on fuel sending unit? Not quite sure, any opinions?
