Aftermarket Fuel Tanks For Trucks - Replacement Fuel Tanks. TITAN Fuel Tanks is America's leading manufacturer of high-capacity aftermarket fuel tanks made of military-grade polymer. Our products are market leaders not because they are the least expensive options --- we'll be perfectly straightforward, they're not -- but because the advantages we provide over competing metal tanks make our products overwhelmingly worth the difference in price.
TITAN Fuel Tanks stand out in the market by enabling you to drive your pickup and tow your RV more than twice as long between fill ups. Anyone who travels or pulls a payload knows that factory-equipped fuel tanks in diesel pickups limit range. Not the optimal situation when you want to travel to the remotest of outdoor camping locations with your fifth wheel or travel trailer. Our tanks allow you to extend the range in your pickup by up to 500 miles or more (depending on the make and model of your vehicle). Put an end to the headaches on long road trips; save time, improve range, cut fuel costs and fill up when you want with Titan Fuel Tanks!
