The fuel system supplied comprises of a fuel standpipe,
a quantity of fuel line, shut-off valve, connectors and a
fuel-metering pump.
The diagram illustrates a typical installation using a fuel
standpipe, which is the preferred method for the fuel
take off. This minimises any problems caused by over
pressuring, fuel starvation and air leaks that can occur if
connected to an engine fuel line.
However, fuel can be taken from an engine fuel line if
it is approved by Eberspächer, and the engine / boat
manufacturer (See technical description manual).
Unapproved connection may affect the terms of your
warranties.
Installing the standpipe
The fuel standpipe supplied must only be fitted to the top
of the fuel tank and on an even surface. It must not be
fitted to the side or bottom of the tank.
Install the standpipe as shown.
Positioning the fuel-metering pump
When installing the fuel-metering pump, take into
consideration that it may be audible when in operation,
so it should be installed into an area or onto surfaces
that will not transmit the sound into the accommodation.
The chosen area should also be free from excessive
moisture and the fuel-metering pump must be mounted
with the electrical connections / pressure side uppermost
within the permissible angles shown.
When connecting fuel pipes with a fuel hose always
mount the fuel pipes in a butt joint to prevent any bubbles
from forming.
1 Correct connection.
2 Incorrect connection - bubble formation.
