The Titan Tank 7020399 is a 253.6 Litre (67 Gallon) extra heavy-duty cross-linked polyethylene replacement fuel tank for the 1999-2007 Ford F-Series. It replaces the OE fuel tank and increases the fuel capacity by 31 gallons over stock.

This Titan Tank is corrosion-proof and nearly indestructible but light enough to lift in place by one or two people.
