Adustable Mercury Magnum fuel Pressure Regulator

Mercury OEM heat exchangers have restrictive fuel flow in high horsepower engine applications with superchargers. It is very crucial to provide adequate fuel delivery during high engine load conditions to prevent leaning out cylinders and melting pistons. Most supercharger manufacturers do not address this problem. Arizona Speed and Marine has developed heat exhchangers that can utilize the OEM hose fitting and regulator. This may be one of the most import additions to your fuel system.

NOTE: Modification of the plastic “Cool Fuel” cover housing is required to fit the larger components.

For fuel injected engines: up to 1100 HP – naturally aspirated up to 800 HP – forced air induction

For carbureted engines: up to 1300 HP – naturally aspirated up to 1100 HP – forced air induction
