NEW!     Fuel & Air Pressure Diaphrams

The Air & Fuel Pressure Diaphrams are on the starboard fuel rail.
It's function is to regulate the air and fuel pressure to the fuel injectors and the air injectors.
A faulty pressure diaphram will cause the engine to run rough, stall and have poor performance.

These are NEW original Mercury Marine diaphrams.
They are NOT rebuilt and they are not made in some cheap mould on some island in the Keys.

The Pressure Diaphrams should be installed by an experianced Mercury tech and the pressures should be confirmed.

Optimax Fuel/Air Pressure Regulator Diaphram $188.00
