How about a gas gauge that works!?!

Remember when we were going to St George in my Grandpa's truck pulling our newly acquired dirt bikes? We were halfway between Beaver and Fillmore and I looked down at the gas gauge and it said 1\4 tank... and then 30 seconds later it said 1\8 tank... and then all of the sudden it dropped below empty and the fuel light came on? Yeah, we went from 1\4 tank to out of gas and stranded on the side of the road in the middle of the night in a sum total of about 3 minutes. Lucky for us you had a mostly empty water bottle and I had the finger strength necessary to unclip the tube from my dirt bike gas tank (not an easy task in -30 degree weather... at least thats what it felt like anyway)... 2 gallons and 15 minutes later we were back on the road. That was funny.
