LS Fuel Pump and Fitting Kit for 1991-2005 GM Models
Swapping an LS engine into a 1991 to 2005 GM chassis often reveals weak spots in fuel delivery during sustained rpm runs and this Fuel Pump and Fitting Kit - Various 91-05 GM models remedies that by ensuring steady pressure from the factory tank. By positioning a USA made Walbro 255 liter per hour unit in-tank the system counters vapor lock and pressure pulsation before they can lean out the engine. Precision machined fittings link directly to original fuel lines without adapters preserving a leak free seal and simplifying installation in popular cars and trucks. Corrosion resistant materials and quality checks ensure consistent output and life under the loads of LS or LT swaps.
Inside Tank Pump Placement for Stable Fuel Delivery
The pump is positioned entirely inside the factory fuel tank, taking advantage of existing baffling that controls fuel movement during corners or sudden stops. By housing the Walbro 255 liter per hour pump in tank, the design cuts out external lines that can overheat and cause vapor lock under extended high rpm use. Internal placement also dampens pressure pulsation, delivering a uniform stream of fuel that sharpens throttle response. This method protects engine health by preventing lean conditions that could arise during spirited driving or track sessions.
Precision Machined Fittings for Factory Line Integration
All of the fittings are precision machined in the United States to match the original GM fuel lines for model years 1991 to 2005. These custom connectors eliminate the need for mismatched adapters or cutting of factory lines, ensuring a leak free joint at typical system pressures. Installers benefit from clear flow paths that guide hoses and prevent kinks, simplifying the plumbing process and reducing bench time. When used with the matching fuel line and regulator kit, these fittings create a seamless assembly that boosts reliability under load.
Corrosion Resistant Domestic Construction Ensures Reliability
Components in the kit are crafted from corrosion resistant alloys that stand up to modern ethanol blended fuels and winter road treatments. Domestic fabrication facilities subject each piece to thorough inspections at multiple stages, verifying dimensions and material properties for consistent output. This level of quality control reduces the chance of unexpected failures or fuel contamination over the life of the swap project. The result is durable performance that maintains steady flow and pressure over thousands of miles in diverse driving conditions.
Seamless Swap Fit for 1991 to 2005 GM Chassis
Engineers designed this kit specifically for 1991 to 2005 GM chassis, allowing a direct fit without custom brackets or line modifications. Whether powering an LS or LT engine, the stable fuel delivery supports aggressive acceleration without dangerous lean spikes. By dropping into popular cars and full size trucks, builders can focus on engine mounting and tuning rather than fuel system troubleshooting. The overall fit and finish give the impression of factory installation, keeping project timelines tight and performance on target.
Engineered for precise fit and consistent performance in your LS swap project with durable domestic components.
