Is the Titan 7030313 worth it over a stock tank?

If you tow or drive long hauls, yes. It roughly doubles capacity to 55 gallons and keeps the factory gauge, so you skip many fuel stops. Short-trip drivers won't recover the $1,406.44 price.

Will it fit my Ram 2500?

No. It is listed for Ram 3500 models from 2013 to 2024 with the 6.7L Cummins only. Check your truck's year and model before ordering.

Does it come with a sending unit?

No. It is designed to reuse your truck's stock/OE sending unit, so a failed factory unit would need replacing separately.

How much lower does it hang than the stock tank?

About 2.5 inches lower. That is modest, but worth checking if you run lifted or off-road setups where rear clearance matters.

Can I run gasoline in it?

No. It is for diesel fuel only, matching the 6.7L Cummins.

When is the price lowest?

The best new price seen is $1,406.44 at eBay as of November 3, 2026, against three stores listing it new. Watch for seasonal sales and free-shipping offers, since freight on a tank this size is significant.

Our take on the Titan Fuel Tanks 7030313 Fuel Tank

The Titan Fuel Tanks 7030313 is a 55-gallon direct-replacement diesel tank for 2013-2024 Ram 3500 trucks with the 6.7L Cummins. It bolts in using the stock/OE sending unit and hangs only about 2.5 inches lower than the factory tank, so ground clearance barely changes. The tank is built from at least 1/4-inch material that won't rust or corrode, with rollover vent valves and black-coated galvanized steel mounting straps included. At $1,406.44 at eBay as of November 3, 2026, it sits at the low end of the three new listings, well under what a dealer-installed auxiliary tank setup typically costs.

Pros

55 gallons roughly doubles stock range
Bolt-in install reuses the factory sending unit
Only about 2.5 inches lower than stock
Thick 1/4-inch material resists rust, corrosion and impacts
Rollover vent valves and mounting straps included

Cons

Diesel only, no gasoline or flex-fuel use
Fits Ram 3500 2013-2024 only, not 2500 or other years
No sending unit in the box, so a bad stock unit adds cost
Heavy when full: about 385 lb of diesel alone
Install still means dropping the stock tank
