Are you interested in an EFI retrofit kit, but just can't get past the complication of the fuel system? Available in return and returnless versions, you can rest assured Holley has the solution you need for your EFI fuel pump woes. Now you can convert your factory tank or fuel cell to an in-tank EFI fuel system quickly and easily! The conversion is easily accomplished with basic tools and requires no welding or fabrication. The aluminum module design includes a die cast pump hanger bracket to control pump vibration while also providing a low profile design to fit where space is at a premium. Holley's innovative clamping system and integrated fuel pump makes it easy. Once installed, hook up your fuel lines and your power source/ground and you're off and running! NO hassle! The 255 LPH model supports up to 550 EFI horsepower or 700 Carb horsepower while the 450 LPH module supports up to 875 EFI horsepower or 1100 Carb horsepower (@ 60 PSI at 13.5 Volts / 10.4 AMP Draw). Of course there are many variables, estimates are based on gasoline. Individual systems will vary based on fuel system design, regulator type, fuel cell location, etc...
Features:
  • Easiest Way To Convert Vehicle To An In-Tank EFI Fuel System
  • The Low Profile Design For Added Clearance When Needed
  • Clamping System Allows You To Locate Module Anywhere In The Tank
