Fuel Pump
The
STEYR MOTORS GmbH Marine Engine
is equipped with an electric fuel pump. It is turned “ON” and “OFF”
with the key switch. If the engine is not started within 10 seconds after turning the key switch “ON”, the fuel pump is
automatically turned off.
Fuel System Checks
Fill the tank with the recommended fuel. Keeping tanks full reduces water condensation and helps keep fuel cool,
which is important to engine performance.
Make sure that fuel supply valves (if used) are open, and valve cock seals are absolutely (gas) tight.
NOTE:
Do not dry run fuel pump.
To insure a prompt start and an even run of the engine, the fuel system is to be rinsed by means of the electric fuel
pump (ignition “ON” several times for app. 10 sec.) before starting the engine the first time and/or after every replace-
ment of a fuel filter.
Refill fuel at the end of each day's operation to prevent condensation build up in tank. Condensation formed in a
partially filled tank contaminates the fuel and promotes the growth of microbial organisms that can block fuel filters
and restrict fuel flow.
If the engine is equipped with a fuel/water separator, drain off any water that has accumulated. Water in fuel can
seriously affect engine performance and damage injection equipment reducing engine life expectancy.
STEYR MOTORS GmbH
recommends installing a pre-fuel filter with water separating capability. The filter flow rate
must allow a flow rate of 340 l/h with a maximum permissible pressure drop rate of less than 200 mbar.
Fuel Contamination
In the marine environment, the most likely fuel contaminants are water and microbial growth (black “slime”). Gener-
ally, this type of contamination is the result of poor fuel handling practices. Black “slime” requires water in the fuel to
form and grow; the best prevention is to change or refill the fuel regularly.
NOTE:
A galvanized steel tank should never be used for fuel storage, because the fuel reacts
chemically with the zinc coating forming powdery flakes which can quickly clog the fuel filters
and damage the fuel pump and injectors.
