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.
