LS Engine Fuel Pump and Fitting Kit for GM 1991-2005 Models
When you fit an LS engine to a GM vehicle from 1991 to 2005, stock fuel pumps often struggle to maintain pressure during extended high rpm sessions. This Fuel Pump and Fitting Kit for 1991 to 2005 GM models positions a USA made Walbro 255 liter per hour pump inside the factory tank to prevent vapor lock and smooth out pressure pulsation. Precision machined fittings integrate with original fuel lines without adapters to ensure a leak free seal and streamline plumbing. With steady pressure under load, the kit supports both LS and LT engine swaps in cars and full size trucks without risking lean conditions.
In Tank Pump Placement for Consistent Fuel Flow
By positioning the US made Walbro 255 liter per hour pump entirely inside the factory tank, this kit leverages the original baffling to control fuel movement during hard cornering or sudden stops. Housing the pump in tank eliminates long external lines that can heat up and trigger vapor lock under high rpm conditions. The internal location also acts as a pressure reservoir, smoothing out pulsation and delivering a uniform stream of fuel that sharpens throttle response. This approach safeguards engine health by preventing lean conditions during extended track sessions or spirited street driving.
Precision Machined Fittings for a Leak Free Assembly
All fittings in this kit are precision machined in the United States to match GM fuel feed and return connections from 1991 through 2005 models. These custom connectors remove the need for generic adapters or line modifications, ensuring a secure seal that holds at high system pressure. Installers benefit from clear flow paths that guide hoses without kinks, reducing bench time and minimizing the risk of leaks. When paired with the matching fuel line and regulator kit, this assembly provides a streamlined plumbing solution for your LS or LT swap.
Corrosion Resistant Domestic Construction for Ethanol Compatibility
Each component is fabricated from corrosion resistant alloys that resist the effects of modern ethanol blended fuels and road salt. Domestic production facilities subject all parts to rigorous dimensional checks and material inspections at multiple stages of the process. This strict quality control ensures consistent output and cut the chance of premature wear or fuel contamination over thousands of miles. The result is durable performance that maintains steady flow and pressure no matter the driving environment.
Direct Fit Integration for 1991 to 2005 GM Chassis
Engineered specifically for GM chassis of the 1991 to 2005 era, this fuel pump and fitting kit drops in without custom brackets or frame modifications. Whether you are converting a compact car or a full size truck to LS or LT power, the system supports aggressive acceleration without lean spikes. By simplifying the fuel delivery upgrade, builders can concentrate on engine mounting and tuning rather than troubleshooting supply issues. The clean fit and factory style finish keep project timelines tight and performance on target.
This kit delivers consistent pressure and a precise fit for your LS fuel upgrade.
