Funny thing happened before an oil change....

[combatmech]

Get in the truck to go change my oil. When I started her up, I noticed that my fuel gauge
started to work. It hasnt worked at all since I bought the truck. It's showing 3/4 full, checked my milage from my last fill up.....sadly, it isnt correct. Should be showing about half full. Good news is, at least I know that something back in the tank is working.

I just bought a M1009 and didn't expect the fuel gauge to work either, well it reads but it sure isn't accurate! Put 15 gallons in instead of the ~7 gallons it said I needed
