Checking feed pressure

NOTE! Normally you do not need to check the fuel
feed pressure. This should only be done when too
high resistance in the system is suspected. If
necessary follow procedures as follows.

TAMD31/41/42, KAMD43

Drill and thread hollow screw to M10x1 as illustrated.
TAMD31: Hollow screw M14, part no. 25167.
TAMD41/42, KAMD43: Hollow screw M12, part no.
969299.

Close the fuel cocks.

Connect the hollow screw to outlet side of the fuel fil-
ter, see the arrow on the filter cover.

Connect nipple 9996666 to the threaded hollow screw.

Pressure is measured after the fuel has passed
through the fuel filter.

Use a fuel pre-filter of correct size to avoid too high
resistance over the filter. The recommended filtration
is 10 m. The fuel filter must not contain parts made of
glass, which can crack.

NOTE! There must be sufficient space around the fil-
ter for inspection and service.

Fuel filter

Fuel flow

The fuel flow is the fuel quantity passing the fuel line
from tank to engine, fuel consumption and fuel return.
This should be considered when selecting the fuel pre-
filter.

The table below shows the fuel flow at rated speed.
