[30 Closed Cab PU]

I do not know an exact level. But hey, this gives you an excuse to go for a drive. Stick a yardstick down the filler hole (if you do not have a spark arrestor), and drive till you get within a few inches of gas in it.


Once it is calibrated full/empty, can always drain, add a gallon at a time, and mark up a stick for comparing level vs. actual gallons. I found out from experience the last 1/4 to 1/8 tank on the gauge goes pretty fast due to the gas tank design. When a newbie I ran out of gas when driving in the country by over estimating how many miles I had left in the tank. The gauge is not linear to actual gas in the tank at the top and bottom of the tank.
