In many cases where aftermarket custom wheels and tires are installed on a vehicle, they are not the same size as standard which means the original equipment spare cannot be used anyway.The STAFS military grade cross-linked polyethylene tank body is light at only 30-pounds, making it easy for one person to handle and includes mounting hardware, a filler kit, and an electronic fuel transfer monitor and control unit which is operated from the comfort of the cab. The electronic system gives the vehicle operator total flexibility in managing how the extra fuel capacity is used.The fuel can be held in reserve or transferred on-the-go as the need arises. The controller's illuminated user interface indicates the tank's fuel level and features a single-touch button that starts the fuel transfer sequence. With one touch, fuel begins transferring from the STAFS tank to the vehicle's primary fuel tank and continues to flow until it is automatically stopped by the controller or the button is touched again.The new TITAN system comes with a universal filler kit featuring an attractive brushed aluminum door that can be installed on the vehicle's exterior sidewall or on an inside wall of the truck bed. All of the mounting brackets, hoses, valves and pump are included with each system.Note: TITAN's STAFS must only be installed on vehicles equipped with heavy Class V (5) hitches, standard on most full-sized diesel pickups. - Super Durable Military Grade Polymer, Cross-Linked Polyethylene (XLHDPE) - Nearly 200 Times Less Heat & Cold conductive than Metal Tanks - 415 Times Less Heat And Cold Conductive Than Aluminum Tanks - Made With Military Grade Cross-Linked Polymer - Titans Polymer Is 1/3 The Weight Of Steel - TITAN Exclusive Product – Award winning - Compatible with most bio-diesel fuel - Manufactured With No Welds Or Seams - No Condensation, No Corrosion - Extremely Tough And Rugged - Does Not Rust Or Corrode - 5 Year Limited Warranty - Reduces Condensation - Tougher Than Metal - Made In The U.S.A. - Easy Installation This Part Fits: Year Make Model Submodel 2001-2005 Chevrolet Silverado 2500 HD Base 2001-2006 Chevrolet Silverado 2500 HD LS 2001-2010 Chevrolet Silverado 2500 HD LT 2007-2010 Chevrolet Silverado 2500 HD LTZ 2004-2010 Chevrolet Silverado 2500 HD WT 2007 Chevrolet Silverado 2500 HD Classic LS 2007 Chevrolet Silverado 2500 HD Classic LT 2007 Chevrolet Silverado 2500 HD Classic WT 2001-2005 Chevrolet Silverado 3500 Base 2001-2006 Chevrolet Silverado 3500 LS 2001-2006 Chevrolet Silverado 3500 LT 2004,2006 Chevrolet Silverado 3500 WT 2007 Chevrolet Silverado 3500 Classic LS 2007 Chevrolet Silverado 3500 Classic LT 2007 Chevrolet Silverado 3500 Classic WT 2007-2010 Chevrolet Silverado 3500 HD LT 2007-2010 Chevrolet Silverado 3500 HD LTZ 2007-2010 Chevrolet Silverado 3500 HD WT 2002-2005 GMC Sierra 2500 HD Base 2001-2002,2006 GMC Sierra 2500 HD SL 2001-2010 GMC Sierra 2500 HD SLE 2001-2010 GMC Sierra 2500 HD SLT 2003-2010 GMC Sierra 2500 HD WT 2007 GMC Sierra 2500 HD Classic SL 2007 GMC Sierra 2500 HD Classic SLE 2007 GMC Sierra 2500 HD Classic SLT 2007 GMC Sierra 2500 HD Classic WT 2002-2005 GMC Sierra 3500 Base 2001-2002,2006 GMC Sierra 3500 SL 2001-2006 GMC Sierra 3500 SLE 2001-2006 GMC Sierra 3500 SLT 2004-2006 GMC Sierra 3500 WT 2007 GMC Sierra 3500 Classic SL 2007 GMC Sierra 3500 Classic SLE 2007 GMC Sierra 3500 Classic SLT 2007 GMC Sierra 3500 Classic WT 2007-2010 GMC Sierra 3500 HD SLE 2007-2010 GMC Sierra 3500 HD SLT 2007-2010 GMC Sierra 3500 HD WT ## Details - **Price:** 2409.81 CAD - **Vendor:** Titan Fuel Tanks - **Type:** Fuel Systems ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 2409.81 CAD | In stock | ## Images - Photo - Primary - Photo - Primary - Photo - Unmounted - User 1 - Photo - Unmounted - User 1 - User 1 - Photo - Unmounted - Photo - Unmounted - User 1 --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/titan-fuel-tanks-01-10-gm-2500-3500-duramax-30-gallon-spare-tire-auxiliary-fuel-system) > Updated: 2026-07-14
