[Vwdiesel] Fuel 101 -- revisited ( OLD old fuel )

Here, in the prairies, stove oil, heating oil and winter fuel all come from
the same tank.  If moisture is at all a concern, use an emulsifier like
Stanadyne products that will take care of the moisture and keep it from
wearing the pump prematurely. It should not be of a concern with this added,
that's why there is a fuel filter. Just use common sense, and add only clean
fuel, not the ooze from the tank bottom.

There was an aftermarket product that used silica gel granules to keep your
tanks dry in highway tractors.  It was a plastic mesh can on a cord you tied
to the chain that retains the fuel filler cap on the semi, and it sank and
rested at the tank bottom.  When it changed color, you were to replace it.
I don't think they are around any more.
