Next message: Terry: "T&T: T&T Racors 2 micron vrs 10 micron"
Hello All
This will be an easy choice if your decision making process uses logic and
common sense as opposed to blindly following advise (from anyone) that cannot
be backed up by logical thought. Using a 2 micron instead of a 10 or 30 micron
will accomplish three things. If your engine stops because of a filter
problem you will know exactly where the problem is. If you use a vacuum gauge it
will give you a much better indication of the condition of the entire fuel
system. Most on engine final filters are placed between the delivery pump and
the injection pump so a restriction in that filter will not show a high vacuum
reading in fact if it's severe enough it can actually cause the vacuum
reading to drop because flow has been reduced. On engine final filters can be
difficult to change especially on a hot engine.
There is no difference in flow rate on a lower micron filter the only
advantage I can see to steeped filtration is that you increase filter area and the
same thing can be done by using a larger primary filter. I believe the 2
micron primary with the on engine secondary still in place as a safety measure to
protect the injection pump in the event of a blow thru of the primary is
definitely the most logical set up. In normal operation the secondary is
receiving fuel that has already been filtered down to 2 micron so it will have great
life. The primary is usually easier to change and the vacuum gauge will show
a much more accurate and complete indication of over all filter condition.
Now I would love to here opposing points of view. But I'm not interested in
hearing this guy said this and he must be correct because he's this.
Manufactures can be very slow at embracing new ideas and mechanics are generally good
at fixing what's broken but there not engineers. If your going to tell me
I'm wrong then back it up with rational thought and logic and maybe I will learn
something.
