DIY In-Tank 200 LPH Fuel Pump Kit for LS Engine Swaps
This in tank kit is designed to supply a stable 200 LPH fuel flow directly from the tank and prevent pressure loss under hard launches and sustained cornering when swapping an LS engine into 1955 to 2005 GM chassis. By combining an internal baffle and a flexible bladder the assembly keeps fuel centered around the pickup to provide slosh control and maintain constant feed regardless of acceleration or lateral forces. Installers benefit from a precision drill guide and factory style flange that align with GM openings without custom plates or welding while the included hanger lock ring and hardware lock the unit securely to deliver reliable operation under demanding driving conditions.
Seamless Drop In Integration for GM Fuel Tanks
The kit's precision flange is CNC machined to match factory tank opening dimensions used on GM vehicles from 1955 through 2005. By relying on exact contour and hole patterns, it removes the need for custom adapter plates or complex welding, producing a true direct fit. The supplied drill guide centers pilot holes and preserves internal clearance between the pump assembly and shell, preventing any rubbing or interference. Proper alignment maintains seal integrity at the flange and eliminates fatigue leaks over time. This seamless drop in solution accelerates project completion while delivering a professional installation quality.
Advanced Dual Slosh Control Mechanism
At the heart of this kit is advanced slosh control achieved through a paired baffle and fuel bladder combination. The internal baffle dampens lateral fuel motion during hard cornering and sudden acceleration, reducing surge inside the tank. Meanwhile the flexible bladder forms a tight seal around the pump inlet to prevent air pockets and ensure continuous liquid feed even at low fuel levels. Together they deliver smoother pressure dynamics under all driving scenarios. The result is predictable throttle response and consistent fuel delivery across hard launches or sustained high-G maneuvers.
All in One Installation Kit for Rapid Retrofits
Every installation component you need arrives in a single package to streamline the fuel pump retrofit process. A specialized hanger provides a secure platform for the pump module while the lock ring clamps the assembly evenly against the tank flange. The precision drill guide locks in place to prevent wandering cuts or mismatched bolt patterns that can complicate service access. By distributing clamp load uniformly around the opening, the system ensures a long term seal and reduces the risk of leaks. Builders spend less time sourcing fittings or hardware and more time refining engine tuning.
Integrated Filter and Regulator for Stable Pressure
The included fuel filter and pressure regulator assembly comes preset to 58 psi with a built in return port to maintain optimal system balance. This dual function module screens out contaminants and holds consistent pressure for LS injectors without requiring extra plumbing or fittings. Its compact design integrates neatly inside the tank and endures repeated cycles of pump operation under track day or highway cruising conditions. Eliminating a separate inline regulator reduces potential failure points and simplifies routing through tight engine bays. Owners enjoy cleaner fuel delivery and reliable performance on long runs or spirited drives.
