LS Swap Fuel Pump Kit for 1991-2005 GM Models
If you are installing an LS engine in a 1991 to 2005 GM chassis, this fuel pump and fitting kit tackles the demand for reliable fuel delivery under high load. Built around the Walbro 255 lph pump, the kit ensures steady fuel flow to prevent lean spikes at high rpm. Each precision fitting aligns with factory fuel lines for a true drop in installation that minimizes fabrication time.
Consistent Fuel Delivery under High Demand
The Walbro 255 liter per hour in tank pump at the heart of this kit delivers a uniform supply of fuel even when the LS engine is pushed to high rpm. By maintaining steady fuel flow, it prevents lean spikes that can stress pistons and valves during intense use. Its internal design also reduces pulsation, ensuring smooth throttle response and reliable power under acceleration.
Seamless Integration with 1991 to 2005 GM Fuel System
Each fitting in this assembly is precisely machined to match factory line sizes on 1991–2005 GM chassis, eliminating the need for custom adapters or cutting. This alignment allows a true drop in installation, saving installation hours and reducing the risk of leaks. Preconfigured routing paths and clear hookups make it straightforward to connect to existing fuel lines and the optional regulator kit.
American Craftsmanship for Long Term Reliability
All components are manufactured in the United States under strict quality standards, using corrosion resistant materials and precision machining. This build integrity translates to fewer service intervals and greater resistance to fatigue on both road and track. Confidence in consistent performance is backed by rigorous oversight at every production stage.
This kit delivers reliable fueling for your LS swap with factory fit and lasting durability.
