LS Fuel Pump and Fitting Kit for 1987-1997 GM Trucks and 1994-1995 Chevy S-10 Pickup
When fitting an LS engine into a GM truck from 1987 through 1997 or a 1994 through 1995 S-10 pickup, maintaining stable pressure inside the tank often stalls progress, and the Fuel Pump and Fitting Kit 1987-1997 pairs a Walbro 255 LPH pump with fittings crafted to match the factory sending unit. Each adapter features corrosion resistant finishes that stand up to ethanol blends and moisture while an optimized flow path preserves output under heavy throttle. Installers drop the assembly into the stock opening, tighten the clamp, and connect directly to the fuel line and regulator without cutting factory lines or sourcing adapters. This precise fit reduces leak points and saves hours on the workbench while ensuring steady fuel flow through the LS engine rpm range.
Optimized Fuel Path Design for Stable Pressure
The kit's internal passages are meticulously shaped to guide fuel from the tank to the LS engine without abrupt changes in direction. By reducing turbulence and minimizing pressure drop, this design helps maintain a consistent supply even under sudden throttle inputs. A stable feed ensures the ECU can meter fuel accurately for both stock configurations and tuned setups, preventing lean spots and enhancing throttle response. This fine tuned path also allows the Walbro 255 LPH pump to operate at its rated capacity, supporting sustained output under heavy load without overworking the unit or risking cavitation in high demand situations.
Hassle Free Fitment to OEM Sending Units
This kit eliminates the need to modify factory lines or hunt for off the shelf adapters by providing fittings that align precisely with the original sending unit ports on 1987–1997 GM trucks and 1994–1995 S-10 pickups. Installers simply drop the assembly into the factory opening, secure the clamp, and make the fuel line and regulator connections. This streamlined procedure reduces installation time, cuts down the chance of error or leaks, and preserves the vehicle's original underbody layout. Both professional shops and do it yourself enthusiasts benefit from a clean, repeatable process that avoids extra fabrication and tool requirements.
Submerged Pump Placement for Cooler Operation and Quiet Running
Encasing the Walbro 255 LPH pump fully inside the fuel tank leverages the natural cooling effect of the liquid medium, keeping operating temperatures in check and extending service life. Immersion muffles mechanical noise, making the system whisper quiet compared with external pump setups. Continuous submersion also shields the unit from road debris and impact damage, ensuring stable performance even in rugged driving conditions. By maintaining pressure without generating excess heat or noise, this arrangement supports both daily driving and spirited acceleration without compromising durability or cabin comfort.
Domestic Build Quality and Corrosion Resistance
Every component in this kit is manufactured in the USA from corrosion resistant materials chosen to withstand ethanol blends, moisture, and road salt. These alloys and coatings resist pitting and chemical attack, preserving dimensional accuracy and sealing integrity over many cycles of thermal expansion and vibration. Strict quality control on domestic production lines ensures each pump and fitting meets exacting standards before it leaves the factory. The result is a fuel delivery system you can trust for reliable operation mile after mile, delivering steady fuel flow and consistent performance in challenging underbody environments.
This kit's precise fit and durable construction ensure reliable fuel delivery throughout your LS project.
