340 LPH Fuel Pump Kit for LS and LT Engine Swaps
When an LS or LT engine swap sends boost and rpm past the limits of a factory tank in 1991 to 2005 GM cars and trucks, fuel starvation can undermine performance and safety. The precision-calibrated 340 LPH Fuel Pump and matching stainless fittings install in the original pump opening with minimal modifications, preserving stock hard line routing on Impala SS sedans, S10 pickups and full size frames. Installation is streamlined by corrosion resistant alloys made in the USA and CNC machined fittings that lock out leaks without adapters or extra clamps. Together these design choices support stable pressure during extended pulls, simplify EFI tuning and help protect pistons rods and bearings by eliminating lean spots under boost.
Seamless Tank Integration for GM 1991 to 2005 Chassis
The 340 LPH Fuel Pump Kit is engineered to slip directly into the original pump opening on GM cars and trucks from 1991 to 2005 without adapter plates or extra tank cuts. By preserving the stock mounting position and factory hard line routing, it reduces the chance of leaks and keeps the chassis architecture intact. Installers benefit from fewer drilled holes and trimmed edges, which speeds swap time and lowers the risk of fuel seepage. Electrical harness connections align with existing channels for quick connector mating, simplifying wiring and diagnostics. The result is a clean, reliable fit that accelerates engine swap projects with minimal alteration to the factory tank.
Continuous 340 LPH Output Under Boost and High rpm Conditions
With a steady 340 liters per hour of flow, the Aeromotive pump delivers consistent fuel at elevated engine speeds and boost pressures common to LS and LT swaps. This reliable output prevents lean spots that can cause detonation or component stress during extended pulls. Matching modern EFI pressure requirements, the assembly enhances throttle response and streamlines tuning by maintaining stable trim maps through every load change. Consistent fuel supply safeguards pistons, rods, and bearings, so drivers can push their Impala SS or S10 builds with confidence. Whether on a straight quarter mile or demanding road course lap, power delivery stays smooth and predictable.
Domestic Corrosion Resistant Alloy for Ethanol and Gasoline
All wetted pump housing parts and fittings are crafted in the USA from specially selected alloys that resist ethanol blends and conventional gasoline. These metals form a durable oxide barrier that wards off rust, pitting, and material degradation even after repeated heat soak cycles. Precision machining holds tight tolerances on sealing surfaces, so internal clearances remain consistent under high vibration and thermal stress. The corrosion resistance extends service intervals and cuts back on upkeep, letting owners focus on driving rather than maintenance. This robust construction underpins years of dependable operation in demanding underbody environments.
Precision CNC Machined Fittings for Leak Free Connections
The kit's stainless fittings are CNC machined to match factory hard lines without the need for splices, adapters, or extra clamps. Each fitting's geometry preserves underbody clearance and avoids interference with frame rails, brake lines, or heat shields. Secure O-ring seals lock out moisture, road debris, and fuel vapor, ensuring a leak free join through harsh thermal cycles and continuous vibration. Maintaining the original routing path keeps hose lengths optimal and minimizes pressure loss. Together with robust clamp hardware, these fittings deliver enduring reliability so fuel delivery remains uninterrupted during spirited driving or extended highway runs.
This kit provides dependable fuel delivery and simplified installation for your LS or LT engine swap.
