340 LPH LS and LT Fuel Pump and Fitting Kit for GM Swaps
When swapping an LS or LT powerplant into a GM chassis from 1991 to 2005, keeping fuel delivery consistent under boost or during prolonged high rpm pulls is essential. This 340 LPH Fuel Pump and Fitting Kit installs directly into the stock tank on Impala SS, S-10 and full size truck projects and delivers LS and LT compatibility without extra adapters. Every component, from the Aeromotive pump to the corrosion resistant fittings, is chosen for reliable service and simple installation. You benefit from sharper throttle response and a steady fuel supply that wards off lean spots and detonation.
Direct Fitment for LS and LT Engine Swaps
Engineered specifically for LS and LT conversions on 1991 to 2005 GM chassis, this kit installs directly into the factory fuel tank without the need for adapter plates. The drop-in design streamlines fitment on Impala SS sedans, S10 trucks, and full-size pickups, preserving factory fuel lines and cutting installation time. By maintaining the original tank opening and pump mounting location, it avoids complex fuel system modifications and keeps the vehicle's underbody layout intact.
Precisely Calibrated 340 LPH Pump for Stable Fuel Pressure
The Aeromotive 340 LPH in tank pump delivers a constant flow rate that meets the demands of boosted and sustained high RPM operation. This measured capacity prevents lean spots under load and reduces the risk of detonation, ensuring the engine remains in its optimal performance window. Matching modern EFI system requirements, it also sharpens throttle response and makes tuning more predictable when pushing horsepower limits.
Corrosion Resistant Materials Ensuring Extended Service Life
Every component of the kit is made in the USA from corrosion resistant alloys that withstand ethanol blends and long-term fuel exposure. These durable materials inhibit rust and degradation in the tank environment, providing consistent service over time. From the pump housing to the precision machined fittings, the robust construction reduces maintenance needs and boosts confidence during spirited driving or track use.
Engineered for consistent fuel delivery and simple installation on LS and LT swaps.
