To help select the correct fuel system you need to know the max horsepower level your build is designed to achieve. Our most popular fuel pump upgrade for standard Hellcat's (non-Demon/RedEye) is our HHP Dual Pump Returnless Fuel System. When this kit is not enough or does not match your build's requirements we have multiple Fore Innovations complete kits that support 1200rwhp with Dual Pumps while the more advanced Triple Pump kits are capable of supporting 1600HP on gas or more. The difference between L2, L3 and L4 is just line routing in reference to the regulator and fuel rails:
NOTE: Dodge Demon and RedEye come factory with dual pumps. We recommend the Fore Triple Pump kits when upgrading these models.
