Lock in 340 LPH Fuel Flow in LS/LT Tanks

Achieve unwavering 340 LPH fuel delivery in LS and LT tanks with a precision CNC baffle and integrated fuel bladder that prevents slosh during hard launches, cornering and braking. Prewired connectors and durable mounting hardware support both EFI and carbureted setups, letting the DIY in Tank Fuel Pump Kit 340 LPH install directly in the tank to upgrade induction or engines without swapping pumps. Corrosion resistant components fit factory and aftermarket tanks to cut installation time and eliminate extra modifications for a seamless, performance focused upgrade.

340 LPH In-Tank Fuel Pump Kit for LS and LT Engine Swaps

Tackling fuel starvation in custom LS and LT engine installs the DIY in Tank Fuel Pump Kit 340 LPH delivers a reliable supply under load. Featuring an internal baffle paired with a fuel bladder it traps liquid around the inlet to prevent air slugs during hard launches cornering or braking. Built for both EFI and carbureted setups the kit includes a hanger lock ring assembly and precision drill guide to ensure accurate tank opening. With capacity for 340 liters per hour this solution supports future induction changes without swapping the pump so builders can plan horsepower gains with confidence.

Internal Baffle with Integrated Bladder Delivering Stable Flow

The advanced baffle design houses a flexible fuel bladder that captures liquid around the pump inlet, even when the chassis is subjected to rapid acceleration, tight cornering or sudden stops. By preserving a dedicated pocket of fuel at the pickup point, air ingestion and the resulting lean spots are effectively eliminated. This in tank solution removes the need for an external surge reservoir while ensuring uninterrupted volume during peak demand. Drivers enjoy a consistent pressure curve that supports crisp throttle response, whether cruising on the street or pushing limits on the track.

340 LPH Flow Capacity for Future Power Growth

With a rated output of 340 liters per hour, this pump meets the baseline needs of LS and LT engines running either injection or carbureted setups. The generous flow headroom accommodates engine enhancements such as forced induction, nitrous oxide or higher injector duty cycles without requiring a secondary upgrade. Maintaining ample volume under load preserves combustion stability and smooth power delivery across the rev range. Builders gain confidence knowing the fuel system supports potential horsepower increases without a complete pump replacement.

Precision Installation Components for Straightforward Tank Alteration

This complete kit brings together every critical item for an in tank modification, including a hanger assembly, lock ring, precision drill guide and step by step instructions. The drill guide guarantees perfectly centered openings in the fuel tank before any cutting begins, reducing the risk of misalignment or leaks. The lock ring and sealing components fit tightly against the tank wall, preventing fuel seepage under continuous vibration or pressure cycling. By combining hardware and clear guidance, the retrofit process becomes accessible for both seasoned technicians and first time installers.

Durable Construction Resisting Corrosive Fuels and Wear

Key metal parts are forged from stainless steel and corrosion resistant aluminum alloys that stand up to ethanol blended fuel and road contaminants. High grade polymer fittings and seals maintain their integrity under elevated temperatures and aggressive chemical exposure, avoiding deformation or breakdown over time. These material choices extend service intervals, minimize maintenance costs and deliver reliable performance during daily driving or intense track sessions. The result is a fuel assembly engineered to endure both routine and demanding conditions without compromise.
