This piece allows adjustment and precise fine tuning of the 454/502
MPI fuel injection system, which is currently non-adjustable.
Why is this important? When airflow through an engine is changed, the
air-fuel ratio changes generally causing a lean condition (an example
of this is when a modified exhaust system is installed). If the engine
were carbureted a simple jet change would take care of any tuning issues.
With the 454/502 MPI fuel injected Mercury Magnum engine there is no
provision for fuel adjustment. Now, with the new Vortech Marine Fuel
Optimizer fuel adjustment is possible.
The Vortech Marine Maxflow Fuel Optimizer is precision machined from
T6061 T6 aluminum and anodized in corrosion resistant blue. This piece
is detailed with the Vortech Marine logo laser engraved on the side.
The Maxflow Fuel Optimizer attaches to the stock fuel pressure regulator
(modification to the stock pressure regulator is required), allowing
easy adjustment from 25-70 psig.
The Maxflow Fuel Optimizer comes with a new housing, retaining clip,
spring, O-ring, brass adjustment screw, stainless jam nut, stainless
mounting hardware and installation and tuning instructions. Installation
should be performed by someone with a good working knowledge of Mercury
MPI fuel injection system.
