2001-2010 GM HD 30 Gallon Spare Tire Auxiliary Fuel System (4010201)

Spare Tire Auxiliary Fuel System for 2001-2010 GM 2500 and 3500 pickups, Diesel (Duramax) trucks only. The 30 gallon XLHDPE tank hangs where the spare used to live, and a one-touch in-cab controller pushes fuel forward to the factory tank whenever you want it, so a truck that stops every 400 km can run most of a day. Early LB7 trucks also need the 0101310 breather kit, see the notes.

Features

• Tank body moulded from military grade cross-linked polyethylene (XLHDPE), no welds or seams
• Will not rust or corrode, and the polymer passes far less heat and cold than steel or aluminum, so condensation stays low
• Tank body is about a third the weight of a steel tank, roughly 30 lb, so one person can handle it
• Mounts underbody in the spare tire position, leaving the whole bed free for hauling
• In-cab controller shows the auxiliary level and starts a transfer with one touch
• Each transfer runs the pump for about 10 minutes and moves roughly 5 gallons, stopping on its own if the main tank fills
• Controller wiring is just power and ground, nothing spliced into the truck's harness or computers
• Universal filler kit with a black aluminum door, mounts on the bed side or inside the bed wall
• Brackets, hoses, valves and pump all come in the box
• Compatible with most biodiesel blends; diesel fuel only
• Made in the USA

The Spare Tire Auxiliary Fuel System trades the factory spare location for 30 extra gallons. If you have gone to bigger wheels and tires the stock spare no longer matches anyway, and the bed stays open for a toolbox, a fifth wheel or whatever you haul.
