Cut the vacuum line on the fuel pressure regulator and install the supplied three way-fitting.
Install the supplied 4mm hose to the three way-fitting and route the hose in.
Hose should go to the back of the control box on the PRofec-B Spec II. Not the Valve Unit.
Please make sure that the 4mm hose is secured with zip ties after the installation to prevent them from disconnecting.
Mitsubishi have fuel pressure controlling solenoid valves. Make sure to get the pressure from the line between the intake manifold and the solenoid.
When routing the 4mm hose through the firewall, make sure not to kink this hose. Kinked hose will cause the unit not to function properly.
