MuscleRods LT Engine Swap Kit for 1988-1998 Chevy/GMC C1500 and 1992-1999 Tahoe/Yukon 2WD
The 340 LPH Fuel Pump and Fitting Kit for GM models from 1991 through 2005 supplies the flow needed for LT engine installations in 1988 through 1998 C1500 and 1992 through 1999 Tahoe and Yukon chassis. Equipped with a tank mounted pump, a matched pressure regulator, stainless steel fittings, a precision bracket and a detailed wiring harness, the kit replaces the factory unit without cutting original fuel lines. Installation is straightforward thanks to dedicated mounting brackets, quick connector pigtails and plug in sensors that link directly to the stock wiring harness. By delivering consistent fuel pressure under sustained throttle openings, this solution helps maintain safe air fuel ratios across the rev range and supports late model GM engine calibration without risk of starvation.
Consistent Fuel Pressure with Tank Mounted Pump and Matched Regulator
The 340 LPH pump installs inside the factory tank to deliver a steady stream of fuel to LT V8 engines in GM trucks and SUVs. By pairing this high volume pump with a matched pressure regulator, the kit holds consistent pressure under sustained throttle openings, preserving safe air fuel ratios. Locating the pump in the tank also reduces noise and helps maintain cooler operating temperatures. The regulator relieves excess flow through return lines, preventing lean conditions during rapid load shifts.
Leak-Proof Stainless Steel Fittings and Precision Bracket Assembly
All fuel line connections in this kit use stainless steel fittings to withstand pressure cycles and resist corrosion common in gasoline environments. These alloy fittings maintain seal integrity over time, reducing the chance of leaks under constant vibration and thermal expansion. A CNC laser cut bracket precisely positions the pump and regulator inside the tank, ensuring proper orientation and secure mounting. The bracket's one piece design eliminates adapter plates or shims, so installers achieve repeatable alignment with minimal adjustments.
Plug in Wiring Harness with Quick Connector Pigtails
The custom wiring harness arrives ready to plug into the factory loom, removing the need to splice or rewire circuits. Quick connector pigtails mate with the pump and regulator sensors, and each plug is keyed to prevent misconnection. The harness integrates with stock power and ground locations, simplifying routing beneath the vehicle. With detailed color coded wires and factory style terminals, technicians can complete electrical connections in minutes and maintain reliable signal transmission for proper fuel pressure management.
