Mine says it's at half full always, even if it's completely full, or almost completely empty, it always says half full... Until I run out of gas, then it goes down to 1/4 tank. It's annoying, but now I just rely on the odometer.
Seems to work OK. Stays on F for a long time after a fill up then quickly plummets to E. Haven't run out of gas so it must have a gallon or two left when on E. Haven't pushed it to know exactly how much.
mine is fairly accurate, except when it gets to about 1/8 of a tank its empty. also... when it gets to 1/4 it shuts off when i make a left turn. starts right back up and does fine until the next left turn or re-fuel. I tell my wife when it shuts off - that's the "low fuel" alarm. any ideas on how to fix this?
No! Stays on "full", even when a trip to gas station takes 12 gals to full - 92 Basic YJ - new to me - needs lots of maint. Plan is to ensure reliable ground first, then go after the sending unit. Mean time, I'm with BillMichaels - will use odometer even if most of my miles are off-road and half in low-4WD.
A couple months ago I replaced the pump and sending unit ( 20 gal unit), and modded the tank. I haven't taken it down below 1/2 tank yet. When it hits 1/2 a tank, it takes about 9 gallons or so to fill it up. So, my gauge seems to be fairly accurate. When it gets warmer, I might try to run it down to 1/4 tank.
