LS Fuel Pump and Fitting Kit for 1987-1997 GM Trucks and 1994-1995 Chevy S-10 Pickups
When installing an LS engine into a 1987 to 1997 GM truck or a 1994 to 1995 S-10 pickup, maintaining tank pressure can slow any project. This Fuel Pump and Fitting Kit 1987 to 1997 includes a Walbro 255 LPH tank mounted pump matched to adapters that align with the stock sending unit ports for a drop-in fitment. Crafted from corrosion resistant alloys, these fittings guide fuel through an optimized flow path that preserves output under heavy throttle. Installers simply lower the assembly into the factory opening, tighten the clamp, and connect directly to the fuel line and regulator without cutting factory lines or sourcing adapters to achieve steady fuel flow across the LS rpm range.
Precision Adapter Design for Original Sending Unit Ports
This kit provides custom fittings that align perfectly with the original sending unit openings on 1987 to 1997 GM trucks and 1994 to 1995 S-10 pickups. By matching the factory port spacing, installers avoid cutting fuel lines or hunting for aftermarket adapters. The precise fit reduces potential leak points and maintains the vehicle's underbody layout without extra fabrication. Both professional shops and home mechanics benefit from a straightforward drop-in procedure that saves hours in labor and minimizes the chance of errors. The streamlined design ensures a secure seal and consistent connection every time.
Optimized Flow Path for Consistent Fuel Delivery
Internal passages in the adapter are shaped to guide fuel smoothly from the tank to the LS pump inlet, minimizing abrupt changes in direction. This careful shaping reduces turbulence and pressure drop, allowing the Walbro 255 LPH pump to operate at its rated output. Under sudden throttle demands, the system maintains steady fuel pressure, preventing lean spots and ensuring the engine control unit can meter fuel accurately. Consistent delivery also supports tuned setups by preserving supply even at high rpm. The result is improved throttle response and reliable performance under any driving condition.
Tank Mounted Pump for Cooler Operation and Quiet Running
Positioning the Walbro 255 LPH unit fully inside the fuel tank leverages the cooling effect of the liquid medium. Heat generated during high demand is dissipated quickly, extending the service life of internal components. Immersion in fuel also muffles mechanical noise, delivering a whisper-quiet experience compared to external pump installations. Continuous submersion shields the assembly from road debris and impact, ensuring stable operation even on rough terrain. This arrangement supports both daily commuting and spirited acceleration without added noise or heat buildup.
Corrosion Resistant Construction for Ethanol Blend Durability
Every fitting and housing in this kit is made in the USA from alloys chosen for their resistance to moisture, road salt and ethanol blends. Specialized coatings protect against pitting and chemical attack, preserving sealing surfaces through repeated thermal cycles and vibration. Domestic manufacturing ensures each unit meets strict quality standards before shipping, delivering consistent performance mile after mile. By resisting corrosion and wear, these materials maintain dimensional accuracy and reliable sealing over the life of the LS swap project. The result is a dependable fuel delivery system you can count on in any environment.
Engineered for a precise fit and dependable performance in your LS swap project.
