Our take on the Titan Fuel Tanks 7031214 Fuel Tank

The Titan Fuel Tanks 7031214 is a 39-gallon direct-replacement diesel tank for 2019 RAM 1500 EcoDiesel trucks. It is molded from cross-linked polyethylene with no welds or seams, so it will not rust or corrode, and it bolts in mid-ship using black-coated galvanized steel straps. It reuses the stock sending unit and adds a rollover safety vent valve. At $759.05 at Parleys Diesel Performance as of November 3, 2026, it is the lowest of three new prices; the tank typically sells in the $700 to $900 range, so this sits near the low end.

Questions and answers

Is the 39-gallon Titan tank worth it over the stock tank?
If you tow or drive long distances, the extra capacity cuts fuel stops noticeably. For short daily driving, the stock tank is cheaper and simpler.
Does it fit my truck?
It is made for 2019 RAM 1500 trucks with the EcoDiesel engine. It is not listed for gasoline models or other model years, so confirm your year and engine before buying.
Do I need a new fuel sending unit?
No. The tank is designed to reuse the stock sending unit, which must be transferred from the old tank during install. If your stock unit is failing, replace it at the same time.
Can I install it myself?
It is a bolt-in swap using the included straps, but it means dropping the stock tank and moving the sender. Expect several hours and a second person for the heavy lift.
Will it rust?
No. The tank is cross-linked polyethylene with no welds or seams, so it does not rust or corrode. The mounting straps are galvanized and coated steel.
When is it cheapest?
The best new price seen is $759.05 at Parleys Diesel Performance as of November 3, 2026. Prices across the three stores move, so compare before ordering.
