340 LPH Fuel Pump Kit for LS and LT GM Engines
When stock tanks struggle to feed LS and LT powerplants under boost and high rpm loads, the 340 LPH Fuel Pump assembly delivers reliable flow without cutting into the factory tank. It slips into GM chassis from 1991 to 2005 with minimal tweaks and precision fittings maintain original fuel line routing on Impala SS sedans, S10 pickups and full size trucks. Installers benefit from fewer drilled holes and trimmed edges, speeding swap time and reducing potential leak points. Designed to match modern EFI pressure specs and resist ethanol corrosion, this kit ensures crisp throttle response and stable tuning through sustained pulls.
Effortless Integration into Factory Fuel Tank
This kit is engineered to slip into the original fuel pump opening on GM chassis from 1991 through 2005, eliminating the need for adapter plates or cutting into the tank wall. By preserving the stock mounting position and factory hard line routing, it maintains the chassis architecture as intended by the original designers. Installers benefit from fewer drilled holes and trimmed edges, which reduces the chance of fuel leaks and cuts installation time. Electrical wiring harnesses align with existing routes for quick connector mating and straightforward diagnostics. The result is a clean fit and reliable performance that accelerates engine swap projects with minimal chassis alteration.
Sustained 340 LPH Pump Output for Boosted LS and LT Engines
Delivering a consistent 340 liters per hour, this in-tank pump meets the intense demands of forced induction and prolonged high rpm operation without pressure dips. Steady flow under load prevents lean conditions that can lead to knock or component stress, helping safeguard pistons, rods, and bearings. The pump's output range aligns with modern EFI pressure specifications, yielding crisper throttle response and more predictable fuel trims during tuning sessions. Whether accelerating an Impala SS on a street quarter mile or powering an S-10 on a road course, you get consistent fuel delivery at every engine speed. This stability translates into smoother power delivery and reduced risk of tune setbacks.
Corrosion Resistant US Made Alloy Construction
All wetted parts and housing components are manufactured in the USA from corrosion-resistant alloys selected to withstand ethanol blends and conventional gasoline. These metals develop a protective oxide barrier that wards off rust and pitting, even after repeated heat soak cycles. Precision machining ensures tight tolerances for sealing surfaces, maintaining integrity under temperature swings and high vibration environments. The result is a pump assembly that delivers dependable service year after year. Minimal maintenance requirements mean owners spend less time on upkeep and more time enjoying reliable performance.
Precision Machined Fittings Ensuring Leak Free Connections
The included fitting set is CNC machined to match factory hard lines without requiring splices, adapters, or special clamps. Each fitting's geometry is optimized to preserve underbody clearance and avoid interference with frame rails or brake lines. Secure O-ring seals and corrosion-resistant finishes lock out moisture and road debris, guarding against leaks through harsh thermal cycles and sustained vibration. By maintaining the original routing path, hose lengths remain correct and pressure losses are minimized. Together with robust clamp hardware, these fittings provide a dependable join that stands up to demanding driving conditions.
Engineered for reliable flow and a precise fit in your LS and LT swap, this fuel pump kit ensures consistent performance under boost and high rpm conditions.
