my gauge doesnt work that well so im always puting fuel in but ive nevep put more than 50 bucks in to fill it up and also what kind of range ru guys getting on a tank and also any sugetions to fix the gauge would be nice as well

 

I think they are around 25 gallons

 

the gauge is screwed on mine also and I ran it out of fuel last week and it took 25.3 gallons to fill it, as far as mileage goes I have seen 10 to the gallon pulling 15k load on my gooseneck to 18 on the highway

 

The tanks are 32 gallons.

 

yep. 32 to fill

 

I have owned 2 of them and both of mine had 30 gallon tanksThats even what was in both of the owners manuals.

 

pic sucks sorry but its a pic of fluid capacities: Fuel-30 gallons Engine oil without filter-11 qts. Engine oil with filter-12 qts. cooling system- manual 16 qts. auto. 17 qts. transmission-manual 3.5 qts. auto 11 qts.

 

as for how much per tank.. I usually get 450-500 miles per tank give or take, thats with a 5 speed and 3:55 gears.. and a few mods to help out.

 

The tanks are stamped 30gal embossed/molded right into the plastic on the side. But you can get a tad over 32 in it from completely empty if the vent is working properly.

 

On mine i have 4:11 gears, 5 speed, 4x4, and it has a 30 gallon tank, about 600-800 miles per tank, Im impressed with it. But the mods I've done helped tremendously as far as fuel economy goes.
