LS Fuel Pump and Fitting Kit for 1987-1997 GM Trucks and 1994-1995 S-10 Pickups
If you are converting an LS engine in a 1987-1997 GM truck or a 1994-1995 S10 pickup, accurate fuel delivery can become a stumbling block and the Fuel Pump and Fitting Kit 1987-1997 ensures you have a matched Walbro 255 LPH in tank pump with fittings that mate directly to the factory sending unit. Each steel fitting uses corrosion resistant finishes that stand up to ethanol blends and moisture while optimized passages preserve pressure under heavy throttle. With everything designed to fit stock openings installers avoid cutting lines or sourcing adapters and can rely on steady fuel flow throughout the engine's rpm range.
Precision Flow Channel Design Ensuring Steady Pressure
The internal passages of this kit have been engineered to guide fuel smoothly from the tank to the LS engine, minimizing turbulence and pressure drop. Smooth flow reduces the risk of lean spots during sudden throttle inputs and helps the ECU deliver precise fuel quantities under varying loads. By preserving pressure, the pump sustains a steady fuel flow even during high demand, sharpening throttle response across the entire rpm range. This design also allows the Walbro 255 LPH unit to achieve its rated output without struggle, supporting both stock and tuned engine setups.
Direct Fit Connections Simplify Installation
Fittings are crafted to mate directly with the original sending unit ports on 1987 through 1997 GM trucks and 1994 through 1995 S-10 pickups, eliminating cutting of factory lines and the need for adapters. Installers simply drop the fittings into the stock openings, tighten the clamps, and connect the fuel line and regulator components. This approach reduces assembly time, lowers the chance of leaks, and preserves the clean appearance of the factory setup. Both professional shops and DIY enthusiasts benefit from a straightforward, error resistant process.
Submerged Pump Placement Reduces Noise and Heat
Positioning the Walbro 255 LPH pump fully inside the fuel tank takes advantage of the cooling effect of the liquid, cutting down on operating temperature and mechanical noise. In this environment, the pump runs more quietly than an external unit and maintains consistent pressure under load. Being submerged also protects it from road debris and impacts, extending service life. The high volume output reliably meets the demands of modified or high torque LS engines without pressure sag during aggressive acceleration.
American Made Corrosion Protection for Durability
All components in this kit are manufactured domestically from corrosion resistant alloys and coatings that withstand ethanol blends, moisture, and road salt. These materials resist pitting and chemical attack, ensuring that both fittings and pump internals remain dimensionally accurate and leak free over many heat and vibration cycles. With tight quality control on U.S. production lines, each part arrives ready for reliable service in harsh underbody environments. The result is a fuel system you can count on for consistent operation mile after mile.
Engineered for a precise fit and dependable performance throughout your LS swap.
