Hellcat Fuel Rails – High Flow 6061 Billet Aluminum by MMX

MMX Hellcat Billet Fuel Rails are Here! These all-new billet aluminum fuel rails resolve all the factory shortcomings! While doing R&D with these fuel rails, MMX found the following restrictions on the OEM fuel Rail:

• OEM Rail Pressure Sensor is .230” Inside Diameter
• Drivers Side OEM Rail Connection is .216” Inside Diameter
• OEM Rail Injector Feed Holes are .135” Diameter (TINY!)

• Relocation of the Fuel Rail Pressure Sensor, completely removing any restriction (When the Optional Line Kit is purchased)
• .350 Inside Diameter Injector Feed Holes
• .686 Inside Diameter Fuel Rail for Increased Volume

These fuel rails can be purchased as is, with no fittings, or with our MMX high flow feed line kit!

NOTE: The MMX high flow feed line kit, or a return style fuel system must be used with these rails. If only the rails are purchased, you MUST have either of those two options listed above to properly supply your engine with fuel.

Fitment:

OE 2.4/2.7 Superchargers, Whipple 3.0L Superchargers, KONG 2650 Supercharger

We have a clean solution for an upgraded feed line with our MMX Billet Rails! This feed line kit clicks into the ½ EFI OEM Flex Feed Line (Located at the passenger rear of the engine) and coverts to a 10AN Feed line. This Feed Line transfers to a Y block, with 8AN outlets. The upgraded rail pressure sensor (along with the included PNP electrical extension) is in this Y Block. We have 8AN ORB Plugs included that block the front of each fuel rail, this allows for a cleaner install, less connections to leak, and no restrictive fuel feed lines!
