Product Description
S550/S650 5.0 Dual Pump 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.

- 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.
