2018+ S550/S650 Dual Pump OEM GT500 Fuel System with dual FPDM control

S550/S650 5.0 Dual Pump Lawn Racing Returnless Fuel System (2018+)

This premium fuel system utilizes the OEM 2020+ GT500 dual-pump sending module to deliver reliable 1000+ whp support on E85, while retaining factory-level durability and refinement.

Engineered as a true returnless system, it eliminates the need for a return line—significantly reducing complexity, potential leak points, and installation time. The variable-voltage pumps operate only as needed, minimizing fuel heating and preserving OEM-style pump longevity.

Includes:

• Dual Pump Fuel Hat Assembly
• Dual Pump Plug-and-Play Wiring Harness
• Additional OEM FPDM With Harness

Optional Upgrade: Fuel rail modification kit (required for 800+ hp applications when retaining stock fuel rails)

Note: Professional installation is required. Also known as Lawn Racing fuel system.
