5.6.1. Draining the fuel tank

When working on the fuel system, do
not expose it to a naked flame;
do not smoke.
– Condensation forms due to temperature varia-
tions at the lowest points of the fuel tank.
The condensate must therefore be removed once
a year as follows:
46
– Fit a polyethylene tube ( diameter 4 mm,
length approx. 350 mm) to a commercial
syringe (20 ml or larger).
47
– Run the tube down to the bottom of the tank
and drain off the diesel oil/water mixture.
The specific gravity of water is heavier than
that of diesel oil and therefore a distinct
dividing line should be visible.
– Repeat the procedure several times until the
transparent syringe is full of diesel oil only.
