91-05 GM LS Drop-In Fuel Pump and Fittings

Smooth operation at sustained RPM is guaranteed by the Fuel Pump and Fitting Kit for GM models from 1991 to 2005, with a USA made Walbro 255 LPH in tank pump and application specific fittings that install seamlessly in cars and trucks. This drop in solution supports LS or LT engine swaps by eliminating lean spikes at high engine speeds while delivering consistent flow and proven reliability for conversion projects.

High-Flow LS Fuel Pump and Fitting Kit for 1991-2005 GM Models

Anyone tackling an LS drop into a 1991 to 2005 GM ride knows that fuel starvation at high rpm can spell trouble, and this Fuel Pump and Fitting Kit provides steady fuel flow under sustained load. Built around a USA made Walbro 255 liter per hour pump positioned in the stock tank, the kit includes precision machined fittings for direct connection to factory lines without adapters. Each component is crafted in the United States from corrosion resistant materials and undergoes stringent quality checks so you avoid repeated service visits and keep your build on track.

Steady Fuel Flow from Walbro 255 LPH Pump

At the heart of this kit lies a USA made Walbro 255 liter per hour pump that sustains a uniform fuel supply even when the LS engine is held at high rpm. Its in tank location minimizes vapor lock risk and leverages factory baffling to keep flow constant under lateral forces. The internal design also reduces pressure pulsation, resulting in a smooth throttle response and immediate power delivery. This reliable supply prevents lean spikes that can damage pistons and valves during aggressive acceleration. When every drop of fuel matters in demanding driving situations, consistent flow helps safeguard engine health and track ready performance.

Precision Machined Fittings for Direct Factory Line Connection

Each fitting in this assembly is machined in the United States to match the original line diameters used on 1991 through 2005 GM models. This precise fit eliminates the need for additional adapters or cutting, delivering a true drop in assembly that saves hours in the garage. Because tolerances are tightly controlled, the risk of leaks under high system pressure is vastly reduced. Clear routing paths in the design simplify the hookup to the optional line and regulator kit, making it straightforward to complete a safe and secure fuel circuit. Installers appreciate the balance of accuracy and convenience built into these components.

American Made Components for Lasting Reliability

Manufactured under rigorous quality standards in the United States, every piece in this kit uses corrosion resistant materials to stand up to ethanol blends and harsh operating environments. Strict quality checks at each stage of production mean fewer service visits and greater peace of mind on both road and track. By selecting domestic manufacturing partners and using proven materials, the kit delivers a level of build integrity that supports a broad range of conversions from cars to full size trucks. This commitment to reliable construction translates directly into cost savings over the life of the vehicle.

Engineered in the USA to deliver lasting performance and precise fit for your LS swap project.
