Holley Fuel Management Controller

Holley Fuel Management Controller

Product images may differ from actual product appearance.

The Holley Fuel Management Controller 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 high performance 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 Holley high performance Fuel management products are produced from precision CNC machined billet aluminum and include detailed installation instructions.
