Fuel Pump - External Mounts
An external fuel pump mounts outside the fuel tank, making it a common choice for race cars, classic restorations, and custom builds where an in-tank pump isn’t practical. Whether you’re feeding a carbureted V8 or a high-pressure EFI system, the right pump ensures consistent delivery without starving the engine.
In this collection you’ll find pumps covering a broad range of flow rates, pressure ratings, and fuel compatibility. Key things to consider when choosing:
- Flow rate – measured in gallons per hour (GPH) or liters per hour (LPH); match to your engine’s horsepower target.
- Pressure rating – carbureted setups typically need 4–7 psi, while EFI requires 40–100+ psi.
- Fuel compatibility – verify pump materials are safe for gasoline, ethanol blends, or methanol.
- Mounting & electrical – external pumps often need a relay and proper plumbing; check for included hardware and installation instructions.
For advice on sizing and installation, consult the manufacturer’s specifications and your vehicle’s requirements.

Fits select 2011-2016 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD Crew Cab models (6.6L Duramax).
Protect your fuel system investment with the WCFab FASS Fuel System Relocation Bracket. This precision laser-cut mounting solution moves the lift pump from its standard position to a more protected location underneath the truck, tucked inside the driver-side frame rail just ahead of the fuel tank. By shifting the assembly inward, you effectively move the lift pump and filters out of the direct debris path of the rear tires, reducing the risk of impact damage or contamination.
Designed specifically for Crew Cab configurations, this bracket provides a clean, stealthy installation when paired with FASS short-style filters. It also significantly simplifies fuel line plumbing for owners running a sump-style pickup on the fuel tank. The bracket features a durable semi-gloss black powder coat finish over an epoxy primer base for maximum corrosion resistance against road salt and moisture.
- Relocates FASS lift pump to the interior of the driver-side frame rail
- Precision laser-cut steel construction
- Direct bolt-on installation using pre-existing factory frame holes
- Finished in Semi-Gloss Black Powder Coat with Epoxy Primer base
- Optimized for Crew Cab short-bed and long-bed configurations
