Fuel Tanks

Fuel Tanks: the part that decides how far your build goes between fill-ups

A fuel tank is the reservoir that stores your gasoline or diesel and feeds it, under a stable head of fuel, to the pump and injection system. Beyond just holding volume, the right tank keeps fuel over the pickup during hard cornering, braking and off-camber driving, so you don't lose pressure and stall. That is why people fit aftermarket fuel tanks - either to add capacity for towing and long hauls, or to support a higher-output pump and injector setup on a swap or performance build where the factory tank runs the pickup dry.

What ThreePiece stocks

There are 13 fuel tanks in stock here, spanning 4 brands: Aeromotive with 9 products, Titan Fuel Tanks with 2, plus single entries from Radium Engineering and Bikers Choice. Current pricing runs from $38 to $1,609 - that spread is what's live in stock now, not a standing offer. The range covers a mix of vehicles: Ford Mustang, Dodge Charger, Ram 2500 and 3500, Chevrolet C/K trucks, the Mitsubishi EVO, and Harley-Davidson Softail, with 11 of the 13 products carrying specific fitment data across model years from 1955 to 2026.

How to choose

The split in this category is real and it decides which tank you want. At the top end, the Titan 50-gallon XXL mid-ship tank for the 25-26 RAM 2500/3500 Cummins Mega Cab and the 52-gallon XXL version for the Crew Cab Short Bed are about raw capacity for diesel trucks that tow and travel. For performance and swap builds, the Aeromotive Hellcat swap tank for the 68-70 Dodge Charger and the Aeromotive 340 Stealth Gen 2 tank for the 82-92 Camaro are built to house a pump and keep it fed under load. Two-wheel builds are covered by the Bikers Choice 6-gallon Softail flatside tank. At the low end of the price range you'll find pieces like the Radium EVO X fuel tank pressure plug - a component, not a full tank, so read the product name closely before you buy.

What else you need with it

A tank is one link in the fuel path. A high-capacity or swap tank usually pairs with a matched pump, so check Fuel Pumps before you order. Plumbing the tank to the rail means Fittings and Adapters in the right sizes and threads. Since you'll likely be under the hood, it's worth reviewing sibling categories in the same section like Radiators, Oil Filters and Batteries. All of these sit under the parent Engine Components section.

Fitment and ordering

Because most of these tanks are cut for a specific chassis and year, confirm fitment before you buy. Call our team for fitment help at 813-535-5801 or reach us through contact us. We offer free shipping on all orders and Affirm and Katapult financing is available on the higher-priced tanks.
