Description

The TITAN Spare Tire Auxiliary Fuel System (STAFS) adds 30 gallons of fuel capacity, effectively doubling the range for most post-1999 American-made diesel pickup trucks. It fits in the spare tire space, preserving truck bed capacity. The system features a 30-pound military-grade cross-linked polyethylene tank, making installation easier and includes mounting hardware, a filler kit, and an in-cab electronic fuel transfer monitor and control unit.
