200 LPH In-Tank Fuel Pump Kit for LS Engine Swaps
When swapping an LS motor into a classic or late model GM chassis consistency in fuel pressure during hard launches and sustained cornering can make or break performance, the DIY in tank 200 LPH fuel pump kit solves that challenge by delivering steady flow directly from the tank. It installs directly inside the tank and uses an integral baffle and flexible bladder to keep fluid centered around the inlet and prevent air pockets at low levels. The precision drill guide and factory style flange match GM openings from 1955 through 2005 and remove the need for custom plates or extra fittings. Installers benefit from repeatable alignment as the included hanger, lock ring, and hardware lock the assembly in place for a reliable supply under demanding driving conditions.
Precision Flange Matching GM Tank Openings
The kit's precision flange is machined to match GM fuel tank openings from 1955 through 2005, enabling a true direct fit without the need for custom adapter plates or welding. This factory style contour ensures the hanger sits at the correct depth, preserving internal clearance and reducing the risk of damage during installation or service. By using the supplied drill guide, installers maintain exact hole placement every time, preventing off-center cuts that could compromise seal integrity. The result is a leak free integration that behaves as if it rolled off the assembly line, saving time and eliminating guesswork on any LS swap project.
Internal Baffle and Fuel Bladder for Slosh Control
This in tank design pairs an internal baffle with a flexible fuel bladder to keep the inlet port submerged under all conditions, from aggressive launches to hard cornering and low level runs. The baffle dampens fuel movement and limits surge, while the bladder forms a consistent seal around the pickup tube to prevent air pockets. Together they deliver uninterrupted flow so the pump sees only liquid fuel, yielding stable pressure and immediate throttle response when the engine demands power. This dual method of slosh control transforms unpredictable tank behavior into a rock solid supply line for any LS engine.
Complete Install Kit with Drill Guide and Secure Hanger
Every part required for a smooth installation is included in one package, from the precision drill guide to the lock ring and specialized hanger. The guide locks firmly onto the tank opening to keep the drill bit centered, eliminating wandering cuts and ensuring alignment with factory mounting points. Once holes are in place, the lock ring clamps the hanger assembly evenly against the flange, distributing torque to create a reliable seal. By reducing trips to the hardware store and trimming install time by hours, this all in one kit lets builders focus on tuning rather than hunting parts.
Integrated Fuel Filter and Pressure Regulator Assembly
The included fuel filter and pressure regulator arrive pre set to 58 psi and feature a built-in return port to maintain constant flow through the system. This dual function component screens out contaminants while holding system pressure at the optimal level for LS injectors, removing the need for separate plumbing or extra fittings. Its robust internal design stands up to repeated cycling and extended duty, providing confidence on long highway runs or spirited track sessions. By combining filtration and regulation in one compact module, the kit delivers a cleaner fuel supply and consistent performance under load.
