Looking for a fuel system solution for your 1973-1991 LS or LT Swap Square Body? Look no further! Our brand new 6AN fitting hanger is a clean sheet design, meant to facilitate the installation of the EP381, 255LPH, or 340LPH fuel pump without splicing connectors inside the tank. Every hanger comes standard with two wiring pigtails meant to fit the AC Delco EP381, as well as the Walbro 255LPH and other 340LPH In-Tank pumps. Quantum fuel pump hangers feature a lifetime warranty on both the Quantum fuel pumps themselves, as well as the sending units. Just select your desired pump option from the dropdown menu to get your swap off to a great start!

But wait! Swapping an LS or LT into your square body pickup requires more than just a new fuel pump. The entire fuel system needs to be upgraded in order to withstand the increased demand from a fuel injection system. The Quantum fuel system option takes the headache out of complex part selection and lets you add on genuine Phenix hoses and your choice of a Quantum brand filter/regulator or a Phenix filter and regulator.

QFS-H880 LS Swap Fuel Pump Hanger With 6AN Fittings for 1973-1991 GM Square Body Pickups

If you have spent countless hours in the garage working through LS and LT swaps, the fuel system is where most builds stall out. The QFS-H880 hanger is a brand-new, clean-sheet design built specifically to take the headache out of fueling your Square Body swap the right way.

Purpose-Built for 1973 to 1991 Square Body Trucks

Purpose-Built for 1973 to 1991 Square Body Trucks

This hanger drops right into 1973 to 1991 C10, C20, C30, K10, K20, K30, R10, R20, R30, V10, V20, and V30 pickups. No hacked together brackets, no custom fabrication, no guessing on fit. Just a hanger engineered for the factory tank with the hardware you actually need to finish the job.

6AN Fittings and EFI-Ready Fuel Delivery

6AN Fittings and EFI-Ready Fuel Delivery

LS and LT engines run high-pressure EFI, which means your fuel system has to step up. The H880 features 6AN fittings and includes a submersible high-pressure hose that handles gasoline and E85 equally well. You get the foundation for a proper EFI fuel system without having to piece parts together from five vendors.

No In-Tank Splicing Required

No In-Tank Splicing Required

Splicing wires inside a fuel tank is a recipe for disaster. I have seen more than a few builds come back because of failed solder joints, soaking in gasoline. The H880 comes standard with two wiring pigtails for Walbro-style 255LPH, 340LPH, and AC Delco EP381 pumps, so the splicing is eliminated.

The Clean Sheet Fuel Pump Hanger LS Swap Builders Have Been Waiting For

When you drop an LS or LT into a Square Body, every component needs to talk to every other component. A mismatched fuel system kills throttle response, hurts reliability, and makes the whole build feel like a compromise. The QFS-H880 gives you a real solution designed around how these swaps actually work.

Multiple Pump Options to Match Your Horsepower Goals

Multiple Pump Options to Match Your Horsepower Goals

Whether you are building a mild street truck or a boosted bruiser, the H880 has a pump option for your horsepower target. Choose from 155LPH, 255LPH, 340LPH, 450LPH, 525LPH, or 535LPH pumps, or order the hanger bare and source your own. Match the flow to the build instead of overpaying.

Corrosion Resistant and E85 Ready

Corrosion Resistant and E85 Ready

The H880 features a corrosion-resistant coating and a submersible high-pressure hose that is fully compatible with ethanol-infused pump gasoline and E85. If you are planning a flex fuel tune or running straight E85, this hanger is built to handle the chemistry without breaking down on you over time.

Lifetime Warranty on QFS Components

Lifetime Warranty on QFS Components

Quantum Fuel Systems is American-owned, and we put a lifetime warranty behind our hangers, pumps, and sending units. If a QFS component fails due to defects in workmanship or materials, we replace it. Simple as that. The serialized fuel pump body guarantees coverage, so there is no question down the road.

Frequently Asked Questions

The H880 is a drop-in in-tank fuel pump hanger with a built-in sending unit and 6AN fittings. It mounts your fuel pump inside the factory Square Body tank and delivers EFI-grade pressure up to the engine, giving your LS or LT swap the fuel system it needs to run right.

The H880 fits 1973 to 1991 Square Body GM pickups including the C10, C20, C30, K10, K20, K30, R10, R20, R30, V10, V20, and V30. If you are running the factory fuel tank on any of these platforms and planning an LS or LT swap, this hanger is made for you.

Yes. Select the Hanger Only option from the dropdown if you already have a pump you want to use. Just keep in mind that the two included pigtails are designed for Walbro-style 255LPH and 340LPH pumps as well as the AC Delco EP381, so your pump choice should match that wiring.

Absolutely. The submersible high-pressure hose is engineered for both modern ethanol-infused pump gasoline and straight E85. Every component exposed to fuel is chosen for chemical resistance, so your hanger does not degrade after a season of flex fuel tuning. Run whatever your build calls for without worrying about the hardware.

The hanger is a huge piece of the puzzle, but a full LS swap also requires upgraded fuel lines, a filter, and a regulator to handle EFI pressure. We offer matched fuel system kits with the H880 so you can select a complete setup and skip the hours of parts research.
