QFS-H883 LS Swap Fuel Pump Hanger for 1988-1995 Chevy and GMC OBS Pickups

QFS-H883 is a fuel pump hanger complete with 8AN/6AN fittings engineered specifically to support LS and LT engine swaps in 1988-1995 GM OBS pickups. This drop-in hanger eliminates the need for compression fittings and removes the requirement for splicing electrical connectors inside the tank, simplifying the most challenging stage of any OBS swap.

Engineered for OBS Pickup LS and LT Swaps

Engineered for OBS Pickup LS and LT Swaps

QFS-H883 is purpose-built for 1988-1995 Chevrolet and GMC OBS pickups, providing a drop-in solution for LS and LT engine conversions. The hanger fits the factory tank without modifications, restoring proper EFI fuel delivery for swap builds that demand stable high-pressure flow from the in-tank pump to the engine bay.

8AN and 6AN Fittings for Clean AN Hose Connections

8AN and 6AN Fittings for Clean AN Hose Connections

QFS-H883 features 8AN and 6AN fittings, allowing builders to plumb AN hoses directly to the hanger without compression fittings or adapters. This delivers a cleaner, leak-resistant fuel system that matches the look and reliability expected on a modern LS or LT swap, eliminating the weak points common to budget plumbing.

No In-Tank Splicing Required for Reliable Electrical Connections

No In-Tank Splicing Required for Reliable Electrical Connections

Soldered or crimped splices submerged in fuel are a frequent failure point on swap builds. QFS-H883 eliminates this risk by providing factory-style wiring connections at the hanger, with no need to splice electrical connectors inside the tank. The result is a reliable connection that holds up over years of fuel exposure.

A Clean Sheet Fuel Pump Hanger Built for LS and LT OBS Pickup Swaps

QFS-H883 simplifies the fuel system stage of any OBS LS or LT swap, providing a complete drop-in solution paired with a wide range of pump options. The integrated check valve, corrosion-resistant coating, and submersible high-pressure hose deliver the foundation needed for a swap that runs reliably from the first startup forward.

Multiple Pump Options to Match Horsepower Targets

Multiple Pump Options to Match Horsepower Targets

QFS-H883 is available with a broad lineup of pump options, including Quantum pumps in 155LPH, 255LPH, 340LPH, 450LPH, and 525LPH, plus Walbro F90000267, F90000274, F90000285, and F90000295 pumps from 450LPH to 535LPH. A hanger-only option is offered for builders who already have a pump selected for the application.

Corrosion Resistant and E85 Compatible

Corrosion Resistant and E85 Compatible

QFS-H883 features a corrosion-resistant coating, and the included submersible high-pressure rubber hose is rated for modern ethanol-infused pump gasoline and dedicated E85. Flex fuel tunes are common on OBS LS swaps, and this hanger is engineered to handle the chemistry without degradation across the lifespan of the build.

Lifetime Warranty on QFS Components

Frequently Asked Questions

QFS-H883 is a drop-in in-tank fuel pump hanger with a built-in sending unit and 8AN/6AN fittings. It mounts the fuel pump inside the factory OBS tank and delivers EFI-grade pressure to the engine bay, providing the foundation for a reliable LS or LT swap fuel system without compression fittings.

QFS-H883 is engineered for 1988-1995 Chevrolet and GMC OBS pickups equipped with the factory fuel tank. It is the right choice for LS, LT, EFI, and TBI engine swap applications using the original tank mounting location, supporting builds ranging from mild street trucks to serious boosted horsepower setups.

Yes. Select the Hanger Only option from the pump dropdown if a pump has already been chosen for the build. The hanger is compatible with a wide variety of EFI and TBI fuel pumps, allowing builders to source the specific pump that matches the target horsepower and fueling demands of the project.

Yes. The included submersible high-pressure rubber hose is rated for both modern ethanol-infused pump gasoline and dedicated E85. Every component exposed to fuel is selected for chemical resistance, ensuring the hanger holds up to flex fuel tuning and ethanol-heavy fuel chemistries without breaking down across the service life of the fuel system.

QFS-H883 is the foundation, but a complete LS or LT swap also requires upgraded fuel lines, a filter, and an EFI-rated pressure regulator. Matched fuel system kits are available that pair with the QFS-H883, allowing builders to order a complete fueling solution instead of sourcing parts from multiple suppliers.
