340 LPH LS Fuel Pump and Fitting Kit for GM Fuel Tanks
When your LS swap depends on consistent fuel delivery from a factory tank this 340 LPH pump and fitting kit solves the gap between original hardware and modern injection demands. It includes precision matched fittings that adapt to GM fuel tanks from 1991 to 2005 while delivering stable fuel pressure for engines up to 550 horsepower. Designed for straightforward installation the assembly mounts easily in most GM tank outlets using existing openings and standard hardware. With calibrated components ensuring accurate gauge readings and LS compatibility under demanding conditions this kit provides the reliable fuel supply modern injection systems require.
EFI Ready Calibration for Modern Injection Systems
Our 340 LPH fuel pump kit is designed to meet the exacting demands of electronic fuel injection on LS swaps. Precision matched fittings and an included sending unit adapt to factory gauge electronics for accurate level and pressure readings. This EFI ready design eliminates guesswork in fuel supply by maintaining consistent pressure even under rapid throttle transitions. By ensuring stable delivery, injectors operate within their intended range for clean combustion and reliable response across all RPM ranges.
High Capacity Fuel Flow for 550 Horsepower LS Engines
At the heart of this kit is a robust 340 liter per hour pump capable of supporting engines up to 550 horsepower. The elevated flow rate prevents fuel phase separation and reduces the risk of starvation during hard acceleration. Less pumping effort means reduced heat buildup and longer life for the pump motor. This high flow performance guarantees that injectors receive sufficient fuel volume to meet peak power demands without pressure drop.
Precision Fittings for 1991 to 2005 GM Fuel Tanks
Each adapter in the kit is CNC machined for an exact fit with GM tank outlets from 1991 to 2005. Smooth transitions and tight tolerances eliminate the potential for leaks and minimize vibration induced wear. By matching factory openings, these fittings remove the need for additional adapters or custom fabrication. Installers can trust that every connection achieves a leak free seal and maintains system integrity under pressure.
Installation Using Existing Tank Openings and Hardware
The assembly is engineered to mount directly in most GM tank outlets without modification. Standard hardware is all that is required to secure the pump and fittings in place, avoiding complex brackets or special tools. This straightforward approach shortens installation time and reduces the chance of error during assembly. Even technicians new to LS swaps will find the process intuitive and repeatable across different GM models.
Engineered for a precise fit and dependable performance in your LS swap fuel system.
