66 Gallon*, extra capacity, extra heavy duty, midship replacement fuel tank for 2017-2019 GM 2500HD and 3500HD pickups with Crew Cabs, long beds, and Duramax diesel engines.

Tank comes complete with black coated, galvanized mounting straps. Tapered tank features exclusive low fuel trap design so most every gallon can be used, and is approximately 2” deeper than the stock OEM tank. TITAN’s Generation 6 tanks feature the TITAN Torque Ring™ OEM style sending unit mounting system for easy, positive installation.

This new Chevrolet/GMC tank is made of our famous military grade, cross-linked polymer (XLHDPE). It’s at least ¼” thick and built to outlast all competitors. It’s tougher than steel and more durable than aluminum. Like all fine TITAN products, this new design has undergone extensive testing. Our legendary products are so tough and well-proven that we back them with a Lifetime Warranty+! No cutting, drilling or fabrication required for installation.

Technical Service Bulletin: Effected Vehicles: 2019-to Current GM 6.6L Diesel Crew Cab Short and Long Bed Trucks Issue: Fuel gauge Drops to Empty After Initial Install and Vehicle Driven Approximately 100 Miles. Explanation: The GM trucks have the ability through programming and monitoring to know exactly how much fuel is in the fuel tank as well as fuel consumption based on miles driven and fuel economy. The design of our XXL tanks adds additional fuel volume above the OEM float which in turn will hold the float on full past what the computer thinks is acceptable. The truck will run a system check and see that the Fuel gauge is reading out of specifications and will zero the fuel gauge. This will put the truck into a semi-adaptive learning mode and the truck will start to align the specifications with the current truck parameters. In our experience 4-5 full tanks ran from Full to empty will fix this issue on analog gauges. Truck with digital gauges (such as Denali, AT4, and High Country models) can take up to 10 full tanks to remedy this issue. Recommendations: Run tank from full to empty, do not fill up until tank is close to empty.
