Reviews: TITAN Extra Capacity Fuel Tanks

Fit like a glove took less than two hours on a lift

I tow, so doubling my fuel capacity is a definite must and that means less stops at the pump! It comes with a detailed instructional manual, so it's super easy to install. High quality tank.

Tank looks good and serves its purpose. Stock tank was only 26 gallons and we tow a TT a few hundred miles a year so being able to go a little further between fuel stops is nice. There are a little better priced options from other vendors for larger tanks but opted for the 39 gallon tank. 4wp had the best price with their sale and the install cost was very reasonable.

Great pricing and fast delivery. Being installed now.

Arrived very fast. Easy to install. But you will need to go into truck diagnostics and recalculate DTE.

I love my new tank and the customer service offered through 4WP was GREAT!!!

Great tank! It’s a Beast! 51 gallons ain’t no joke! 2 feet longer towards front of truck.

The tank is a great fit and will allow me to pull the 5th wheel farther without needing to stop and fill up. In most cases it will allow me to drive from camp site to camp site without needing fuel, therefore I can fill up after unhooking.

Excellent upgrade. Increased range, over 800 miles, is a huge benefit. The ability to pick where to fill up is awesome. Dealer or Forscan software can change the gallon capacity in the trucks computer so that distance to empty is accurate. Install took less than 2 hours. Tank has almost paid for itself by never filing up in Ca and avoiding the fuel taxes. Big improvement for 6 3/4 bed with small stock tank.

Rear strap doesn't exactly fit well, and it would be nice if they had some sort of skid plate option for it. Also, the gauge doesn't exactly read the true fuel level, so I just track it based off the odometer.
