Show original supplier description
The MMX HEMI Performance Single Pump Fuel System provides a robust solution for enthusiasts who have installed horsepower-increasing modifications such as upgraded camshafts, ported heads, or superchargers. By delivering 450LPH, this system ensures consistent fuel pressure to prevent engine starvation during high-demand operation, having been successfully tested to 800WHP with a 2650 Magnuson supercharger at 11PSI. Users should consult the provided installation manuals and addendums before beginning the setup process to ensure proper integration with their factory fuel system. Prospective buyers are advised to verify local and state laws regarding emissions compliance before installation, as modifications to fuel systems may affect vehicle emissions status. This system is intended for use in the specific vehicle configurations listed and provides a direct-fit performance upgrade for those seeking reliable fueling for both pump gas and E85 applications.
