Jeff,
There always seems to be a bit of
confusion about "primary/secondary" filters.
Think of the travel of the fuel.
Primary being the FIRST .. filtering.
Most of us have an filter system (such as
a RACOR) mounted on a bulkhead usually in the engine compartment as the first
filter. Therefore the "primary"
So it would go something like
this..
Fuel Tank... RACOR (primary) filter....
Fuel Pump (depending on engine make)... Secondary filter (usually mounted on
engine).. Engine.
A typical RACOR , would have an Inspection
bowl with a water drain at the bottom.
If you do get water in the fuel, the water
being heavier than fuel, will collect at the bottom of the filter bowl. Then it
can be seen and drained.
The Primary is usually Easy to get to so
as to make change out quick and less a hassle.
This "add on" is used to be a
First Line of Attack in the fuel line.
There are other types of filters that
aren't Spin On's or that have water drains.
This is a Common way of doing it but by no
means the ONLY way..
Of course there are many engine makes
.. and each has it's own particular set up.
BTW....There is a great deal of argument
and confusion about whether Fuel Additives are effective.
Most of the Diesel Mechs that I've heard
say:
" Additives DON'T work " and that "
If you must put in BIOCIDES.. Use only the CORRECT
amount"
One diesel guy said " Use Biocides as a
Birth control.. NOT as a killer. You'll only have to clean up the
Bodies" ... LOL
I personally subscribe to the advice of No
Additives except an occasional dose of Biocide.
