Titan’s new 40-gallon rear after-axle polyethylene tank is said to be impervious to corrosive diesel fuels and helps fleets save on maintenance, while extending the service life of Ford F-series trucks.

The new tank is the only one on the market engineered to fit 2011-2015 Ford F-350, F-450 and F-550 diesel cab-and-chassis trucks, says Titan.

Titan’s new tank virtually eliminates the service and maintenance issues associated with diesel fuel-line contamination originating in OE and aftermarket steel fuel tanks, the company says.

For years, widespread problems have been attributed to fuel-related degradation and delamination of the protective linings of steel fuel tanks. Titan’s polymer tanks aren’t susceptible to the chemical and biological reactions that diesel, bio-diesel fuels, and additives are accused of causing in steel fuel tanks. Formed from military-grade, cross-linked polyethylene (XLHDPE), Titan aftermarket fuel tanks can safely be used with the wide array of bio-diesel fuels and blends on the market.

The interior surfaces of both OE and aftermarket steel fuel tanks are commonly lined with a coating that can begin to degrade when exposed to the chemical and biological makeup of many of today’s diesel and bio-diesel fuels, Titan explains. As the coating deteriorates, particles of it are sloughed off, contaminating the fuel source, causing failures along the fuel’s path through pumps, filters and injectors.

Fuel tank delamination is considered a fuel-related issue and is not covered under warranty. Repair costs can mount rapidly and in many cases a new steel tank with the same susceptibility to failure is installed. The recurring problem has become an issue for consumers and public and private fleets alike.

Titan’s new 40-gallon tank, product number 8020011, is designed to replace 2011-2015 Ford original equipment part numbers CC3Z9B210B and CC3Z9002B. The polyethylene tanks are much lighter than their steel counterparts, 200 times less thermal-conductive, and their insulating properties eliminate condensation. These polymer replacement fuel tanks will never corrode and have a rollover vent valve with a vent hose and drain plug.

The new tanks are easy to install and come in kit form. The vehicle’s stock fuel sending unit can be reused and replacement skid plates, straps, and ancillary components ordered from any Ford dealership. All Titan replacement fuel tanks are backed by a five-year limited warranty.
