I have been riding in my 65 C-10 for the past couple years without a working fuel gauge. Been telling myself that I'm going to fix it when i change tanks. I just fill up every evening right by my house. That way in the morning i know i have a full tank and no worries if im running late 4 work. I also keep a 5 gal can in the back for "just in case". Had to use it once... If you do keep a can though ... I recomend emptying it into the tank every other time or so that you fill up. That way the gas doesnt get old on ya.
