I have the long bed and went with a 30 gallon tank. My low fuel light usually goes of at about 5 gallons left. I think the furthest I ever pushed it I put 28 gallons in the tank.

P.S. I have noticed a difference in my milage on the times I filled up from half a tank....Always gets lower milage. That extra weight does make a difference.

Rocks

 

The most I ever put back was 22.05 gallons. I was low enough to be worried but apparently I had plenty left. Kind of makes me wish we still had dual tanks. If you always alternated tanks and filled up after it was empty you never would run out.

 

ya dual tanks would rock, one for the 94 chevron and one for race gas.

u wanna race the L?? slap different program on the chip and swich to the race gas tank
