200 LPH DIY In-Tank Fuel Pump Kit for LS Engines
A classic GM chassis that houses an LS swap demands precise fuel delivery and the DIY in Tank Fuel Pump Kit 200 LPH addresses that need by maintaining steady flow from the tank. Engine installers will appreciate the integrated baffle and flexible bladder that work together to deliver slosh control and prevent fuel starvation under high G loads. This kit drops directly into 1955 to 2005 GM fuel tanks with a CNC machined flange that matches factory contours and bolts without custom plates or welding. Included drill guide, hanger lock ring and hardware secure the assembly in place to preserve seal integrity and support consistent performance under demanding driving conditions.
Precision Flange Integration For 1955 to 2005 GM Fuel Tanks
The flange at the heart of this kit is CNC machined to match the factory tank opening dimensions used on GM models from 1955 through 2005, ensuring a true drop in installation without requiring custom plates or welding. This precision fit preserves the original tank contour and bolt pattern to maintain consistent sealing pressure around the perimeter. By using the supplied drill guide to locate pilot holes, installers avoid misalignment that can cause rubbing or interference between the pump housing and tank shell. Uniform clamp force is delivered by the hanger lock ring, which locks the module in place and prevents fatigue leaks even under repeated thermal cycles and vibration.
Engineered Dual Slosh Control With Internal Baffle And Fuel Bladder
Maintaining a steady fuel supply during hard launches and cornering is critical for LS swap applications, and that begins with an advanced slosh control strategy. The internal baffle dampens fluid motion inside the tank, reducing surge that can starve the pickup under lateral forces. In parallel, a flexible bladder forms a continuous seal around the pump inlet, keeping fuel centered even when levels drop and preventing air ingress. Together these components stabilize pressure delivery and protect against erratic flow, yielding reliable throttle response across every driving scenario.
Streamlined Installation Process With Drill Guide And Lock Ring Hardware
The all in one kit approach brings every critical component in a single package to speed up the retrofit process on classic chassis. Installers first secure the precision drill guide into the factory opening, which keeps the pilot holes perfectly centered and prevents wandering that could damage internal clearances. The included hanger supports the pump module at the correct depth, while the lock ring clamps the assembly evenly, preserving seal integrity over the full circumference of the flange. By cutting out extra trips for fittings or fasteners, this system slashes install time and simplifies service access for future maintenance.
Integrated Fuel Filtration And Pressure Regulation Assembly
The kit's self contained filter and pressure regulator assembly arrives preset to 58 psi, delivering clean fuel at a constant pressure to your LS injectors without the need for additional plumbing. The built in return port balances system flow, preventing pressure spikes and maintaining optimal injector spray patterns under varying engine loads. Compact enough to reside entirely within the tank, this module reduces potential leak points and simplifies routing through tight engine bays. For long durations on road or track, owners gain confidence in consistent performance and reduced risk of fuel contamination.
