Vehicle Fitment

• 2011-2016 Chevrolet Silverado 2500HD (6.6L LML Duramax, Crew Cab only)
• 2011-2016 Chevrolet Silverado 3500HD (6.6L LML Duramax, Crew Cab only)
• 2011-2016 GMC Sierra 2500HD (6.6L LML Duramax, Crew Cab only)
• 2011-2016 GMC Sierra 3500HD (6.6L LML Duramax, Crew Cab only)

Fitment Notes

• Crew Cab configuration ONLY - NOT compatible with Regular Cab or Extended Cab (Double Cab) models. Frame rail geometry differs on shorter cab configurations.
• Designed specifically for the 2011-2016 LML Duramax platform - not compatible with earlier LBZ/LMM or later L5P applications.
• Bracket mounts to the inside of the driver side frame rail using pre-existing holes - no drilling required.
• Best used with FASS short-style filters for a fully concealed, stealthy installation.
• Simplifies fuel line routing when using a sump-style pickup on the fuel tank.

Features

• Precision laser-cut steel bracket relocates the FASS lift pump to underneath the truck, just in front of the fuel tank on the inside of the driver side frame rail.
• Moves the FASS unit out of the direct debris path of the rear tires, reducing exposure to road debris, mud, and rocks that can damage the pump or fuel lines.
• Bolts directly to pre-existing frame holes - no drilling, cutting, or modification to the truck frame required for installation.
• Finished with a zinc epoxy primer base coat followed by a semi-gloss black powder coat for superior corrosion resistance in underbody environments.
• All-position mounting provides a stealthy, hidden installation that keeps the FASS system out of sight from outside the vehicle.
• Includes all Grade 8 hardware required for a complete, ready-to-install package.
• Made in the USA at WCFab's Sandwich, Illinois facility.
• Installs with basic hand tools - no professional fabrication required.

Product Description

The Wehrli Custom Fabrication WCF100269 is a precision laser-cut FASS lift pump relocation bracket engineered specifically for 2011-2016 LML Duramax Crew Cab trucks. The factory FASS mounting location on these trucks positions the lift pump in an exposed area vulnerable to road debris thrown by the rear tires - a known issue for Duramax owners who run their trucks in off-road, farm, or heavy hauling environments. This bracket solves that problem by relocating the FASS system to the inside of the driver side frame rail, just in front of the fuel tank, placing the pump in a protected, recessed position where it is shielded from tire debris and road contamination.

Installation is straightforward and requires no drilling or modification to the truck's frame. The bracket bolts directly to pre-existing holes in the driver side frame rail using the included Grade 8 hardware, and can be completed at home with basic hand tools. When paired with FASS short-style filters, the result is a fully concealed, stealthy installation that hides the lift pump from view entirely. This layout also simplifies fuel line routing for owners using a sump-style tank pickup, reducing line length and improving the overall cleanliness of the fuel system installation.

The bracket is finished with a zinc epoxy primer base coat beneath a semi-gloss black powder coat - a two-stage corrosion protection system that is far more durable than a single-coat finish for an underbody-mounted component exposed to moisture, salt, and debris year-round. Made entirely in the USA at WCFab's Sandwich, Illinois facility, this bracket reflects the same precision fabrication standards applied across the entire WCFab product line. Note that this bracket is designed for Crew Cab configurations only and is not compatible with Regular Cab or Extended Cab models, where the frame rail geometry does not accommodate the same mounting position.
