340 LPH LS Fuel Pump and Fitting Kit for 1991-2005 GM Models
When installing an LS engine into a 1991 through 2005 GM platform the 340 LPH Fuel Pump and Fitting Kit - Various 91-05 GM models takes on the challenge of matching fuel volume and pressure requirements from idle to full throttle. It features a 340 LPH pump paired with precision aluminum fittings that interface directly with the factory tank outlet and standard fuel lines on these GM trucks and cars. Installation remains straightforward thanks to a direct fit wiring harness adapter and high quality pressure rated seals that hold steady under sustained load. With stable flow through every driving condition this kit safeguards against fuel starvation during spirited accelerations or track sessions.
Precision Aluminum Fittings for Direct Tank Outlet Connection
The precision machined aluminum fittings in this kit interface seamlessly with the factory tank outlet and standard fuel lines on 1991 to 2005 GM chassis. Each fitting is crafted from billet aluminum and finished to tight tolerances, ensuring a leak free junction even under varying thermal and vibration loads. Aluminum offers strong corrosion resistance compared to steel and helps keep overall system weight down. By matching the contours of the stock outlet, these fittings maintain proper fuel routing and pressure, reducing the need for additional adapters or custom line fabrication. Installers will appreciate how the accurate fit promotes a clean engine bay layout while delivering reliable performance from idle to full throttle.
High Capacity 340 LPH Pump Delivering Steady Flow Under Demand
This kit incorporates a 340 liter per hour pump that meets the fuel flow requirements of LS engines during hard acceleration and extended high rpm operation. The pump's internal electric motor and precision impeller are engineered to sustain consistent pressure across the entire operating range, minimizing the risk of fuel starvation at wide open throttle. With a capacity that supports engines well above stock output, tuners can pursue power upgrades without fear of supply restrictions. The result is smoother throttle response and stable combustion even under heavy load or track use. Field tests confirm that flow remains stable across temperature extremes, for peace of mind in every driving condition.
Direct Fit Wiring Harness Adapter for Hassle Free Electrical Hook Up
Wiring the fuel pump is simplified by a direct fit harness adapter that plugs into the vehicle's stock connector without cutting or splicing. This adapter retains factory style connectors and circuit protection, preserving the original wiring integrity and avoiding potential points of failure. Technicians benefit from reduced installation time and eliminated guesswork, as no special tools or crimping procedures are required. The harness also integrates a protected relay mount, allowing the pump to draw steady current while safeguarding the control circuit from overload. Together, these design choices ensure a robust electrical interface that stands up to continuous duty.
Durable Seals Maintaining Leak Free Operation Under Pressure
The kit includes high quality pressure rated seals that hold steady under sustained load and fluctuating system pressures. Manufactured from a heat resistant elastomer, these seals maintain elasticity and sealing force even after repeated thermal cycles. Their precision molding matches the geometry of each fitting port, eliminating minor gaps that can lead to drips or air infiltration. By preserving proper pressure throughout the fuel system, these seals play a vital role in preventing vapor lock and maintaining pump efficiency. The result is a trustworthy fuel delivery network that requires minimal maintenance once installed.
