340 LPH LS Fuel Pump and Fitting Kit for GM Fuel Tanks
If your LS swap is plagued by inconsistent fuel flow under sustained load in a 1991 to 2005 GM chassis, the 340 LPH Fuel Pump and Fitting Kit for GM Fuel Tanks was engineered to maintain a steady supply to protect engine components. It couples a 340 liter per hour pump housed inside the tank with factory spec fittings and durable hoses that arrive ready to bolt in, eliminating clearance conflicts around brake lines and exhaust tubing. Precision machine tolerances ensure leak free connections to both fuel rails and chassis hard lines, while the keyed alignment prevents twisting under torque for reliable sealing over thousands of miles. On long drives or spirited sprints, this kit delivers consistent fuel pressure to keep injectors active and rails primed, letting your LS engine perform without compromise.
Consistent Flow from a Precision Calibrated 340 LPH Pump
The tank mounted pump at the core of this kit is engineered to deliver a steady 340 liters per hour, preventing pressure drop during sustained highway runs or extended track sessions. Calibrated to work with pulse width modulation controllers, it automatically adjusts output to match engine demand and avoids fuel rail starvation at peak throttle. This stability not only preserves injector performance but also reduces wear on the pump motor by avoiding frequent overcurrent conditions. By balancing both volume and pressure, the design extends the service life of downstream components, even when operating in tight, heat soaked engine bays. Rigorous bench testing ensures that the pump maintains its published output curve over thousands of duty cycles.
Factory Exact Fittings for Seamless GM Chassis Integration
All fittings mirror GM original equipment dimensions and thread forms, so installers can bolt straight onto stock hard lines and fuel rails without adapters or custom brackets. Precision machining guarantees leak free connections that resist vibration and thermal expansion. The fitting bodies are shaped to clear brake lines, exhaust tubes and crossmembers common to 1991 through 2005 frames. A keyed profile on each coupling prevents twisting under torque, locking seals in place for long term reliability. This OEM style match also minimizes the risk of clearance issues that could lead to rubbing or fluid bypass in confined installation areas.
Durable Multi Layer Hoses Preserve Pressure Integrity
Each hose in the kit features multi layer braid reinforcement to resist collapse under vacuum and ensure a consistent internal diameter at high pressure. This construction maintains full flow capacity, even when hoses are routed around tight corners or secured near vibration sources. Corrosion resistant aluminum fittings are crimped onto the hoses and rated for fuels containing ethanol blends, guarding against swelling and leaks. Pre cut lengths align with common LS swap layouts, eliminating excess loops that could trap air or fuel. Together, these elements preserve uninterrupted delivery and protect the system during aggressive cornering or rapid load changes.
Broad Compatibility for Simplified LS Swap Plumbing
This pump and fitting kit supports a wide range of GM models, from fourth generation F body cars to full size trucks of the same era, standardizing the fuel supply upgrade for most LS conversions. All components are matched to stock mounting and routing paths, reducing the need for fabrication or special adapters. By addressing common clearance and alignment challenges, the package cuts installation time and avoids trial and error with line fits. Builders can move quickly from chassis prep to engine tuning, confident that the fuel system will hold consistent pressure under all driving conditions. This plug in style solution brings reliability to both novice and seasoned swap projects.
Engineered to provide leak resistant connections and unwavering flow, this kit ensures your LS swap runs smoothly under every driving condition.
