340 LPH LS and LT Fuel Pump Fitting Kit for GM Models
Converting a GM chassis between 1991 and 2005 to an LS or LT powertrain often exposes factory tanks to flow limits that can cause lean spots and engine stress during high rpm or forced induction events. Designed to drop into the stock pump opening, the 340 LPH Fuel Pump and Fitting Kit uses precision CNC machined stainless fittings to sustain EFI pressure without cutting, welding or extra clamps. Crafted from domestic corrosion resistant alloys, this assembly handles ethanol blends and thermal cycles, and its O-ring sealed fittings lock out leaks while preserving factory hard line routing on Impala SS sedans, S10 pickups and full size trucks for quicker installation and confident tuning.
Seamless Tank Integration on GM 1991 to 2005 Platforms
This fuel pump kit is engineered to install directly into the original tank opening on GM cars and trucks built between 1991 and 2005, eliminating the need for adapter plates or extensive tank modification. By preserving the stock mounting position and retaining factory hard line routing, the design maintains chassis integrity and reduces the risk of leaks. Installers benefit from fewer drilled holes and trimmed edges, which accelerates swap time and simplifies quality control. Electrical harness connectors align with the OEM channels, allowing quick mating and straightforward diagnostics. The result is a clean, reliable fit that gets projects back on the road faster with minimal alteration.
Consistent 340 Liter per Hour Delivery Under Boost
Delivering a continuous 340 liter per hour flow, this in-tank pump sustains fuel volume even at elevated rpm and boost pressures common to LS and LT swaps. That steady supply prevents lean spots that can lead to detonation or component stress during hard pulls. Maintaining modern EFI pressure requirements, the system aids in precise trim calibration and sharper throttle response across load changes. Consistent fuel delivery also protects pistons, rods, and bearings, especially when running ethanol blends or high octane fuels. Whether on a road course or quarter mile drag strip, drivability remains smooth and predictable.
Corrosion Resistant Alloys for Ethanol and Gasoline Environments
All wetted parts are crafted in the USA from corrosion resistant alloys selected to withstand both ethanol blends and conventional gasoline. These metals form a robust oxide barrier that rejects rust, pitting, and chemical degradation even after prolonged thermal cycling. Precision machining holds tight tolerances on sealing surfaces, ensuring internal clearances remain stable under vibration and heat soak. This durability extends service intervals and lowers maintenance costs, letting owners focus on performance rather than upkeep. The result is reliable operation in demanding underbody conditions for years to come.
Precision CNC Machined Stainless Fittings for Leak Proof Assembly
The stainless fuel fittings are CNC machined to exact dimensions so they mate directly to factory hard lines without splices or extra clamps. Each fitting's profile preserves underbody clearance and avoids interference with frame rails, brake lines, and heat shields. A robust seal ring locks out fuel vapor, moisture, and road debris through harsh thermal cycles and continuous vibration. Retaining the original routing maintains optimal hose lengths and minimizes pressure loss. Together with sturdy clamp hardware, these fittings ensure a leak proof connection that withstands spirited driving and long highway runs.
Engineered for a precise fit and lasting performance, this fuel pump kit ensures dependable EFI pressure under boost and eases installation with factory routing retained.
