Water In Fuel - Chevrolet 2005 T-Series Owner's Manual

Water in Fuel

CAUTION:
{
Diesel fuel containing water is still flammable.
You could be burned. If you ever try to drain
water from your fuel, keep sparks, flames and
smoking materials away from the mixture.
Notice: If there is water in your diesel fuel and the
weather is warm or humid, fungus and bacteria
can grow in the fuel. They can damage your
fuel system. A diesel fuel biocide can be used to
sterilize your fuel system. However, your fuel system
may still need to be cleaned. Your dealer can
advise you of the appropriate solution.
If your fuel tank needs to be purged to remove
water, see your dealer or a qualified technician.
Improper purging can damage your fuel system.

Sometimes, water can be pumped into your fuel tank
along with your diesel fuel. This can happen if a service
station does not regularly inspect and clean its fuel
tanks, or if it gets contaminated fuel from its suppliers.
If this happens, a
water-in-fuel indicator light
will come on in the
instrument panel. If it does,
the water must be
drained. Your dealer can
show you how to do this.
