Info

This Fuel Management unit is designed to run in conjunction with the factory fuel pressure regulator. This is the ultimate manual fuel management control unit and is installed in series with a stock regulator in the return line back to the tank. The unit increases fuel pressure in proportion to boost pressure up to a 4:1 Idle/WOT pressure ratio depending on which included adjustable disks you select. This add on upgrade is ideal to be used with aftermarket turbo and supercharger kits that require additional fuel pressure volume as the boost pressure increases. This unit is adjustable from 20-75 PSI, offers two fuel pressure slope settings and is recommended to be used in conjunction with any Holley High volume EFI fuel pump. All Fuel management units are produced from precision CNC machined billet aluminum and include detailed installation instructions.

  • Adjustable from 20-75 psi + boost reference
  • Supplies increasing fuel ratios in respect to boost produced by turbos and superchargers
  • Designed to supply additional fuel for aftermarket turbo and supercharger applications
  • -6 an fittings included
  • Engineered to regulate extreme flow volumes generated by racing fuel systems
