Thanks for the responses so far.

The boat pix is a factory job - the one I passed on cuz instead of
under a hundred, it was more like 500 in the bidding - and I already
had one. OTOH, if anyone knows where to buy the not-filters part of
that, certainly, that's the best way. However, I'll also pour over the
diagrams to see if that makes sense to me. The story about the hose
gave me chills - fortunately, mine's only 1/4" ID, and already bought.

My idea was, indeed, to be able to change the filter on the fly.
Having the ability to use one of them for fuel polishing wasn't my
priority, but interesting. As bouncy as the ride over when we bought
it was, it's possible we can get away without that. However, an ounce
of prevention, etc.

I'll have to sketch it out to see if I can visualize Glenn's - but I'm
sure his engineering mind will have it worked out :{)) Glenn, does it
look diagrammatically like the one before?

Keep those cards and letters coming :{))

And, as always, Thanks.

"Believe me, my young friend, there is *nothing*-absolutely
nothing-half so much worth doing as simply messing,
messing-about-in-boats; messing about in boats-or *with* boats.
In or out of 'em, it doesn't matter. Nothing seems really to matter,
that's the charm of it.
Whether you get away, or whether you don't; whether you arrive at your
destination or whether you reach somewhere else, or whether you never
get anywhere at all, you're always busy, and you never do anything in
particular; and when you've done it there's always something else to
do, and you can do it if you like, but you'd much better not."

Approx. 2/3 of the way down the page. You need 2 three way valves.
The brass valve should work. It is like a tank selector valve on some
older dual tank trucks that had manual selection of fuel tanks.
http://www.jackssmallengines.com/barens_valve_ball.cfm

Each 3way valve will have to be turned to a position so
fuel flows through one filter and then through other valve to engine.
Fuel should flow through filter A or Filter B but not both at the same
time. If one valve is turned the wrong way you will have no flow to engine.



Copy and paste this to a text editor such as notepad. It should become
clear.

Parallel filoter while intuitively a good thought rarely work on a boat
in practice. A high particle challenge situation that 'slug' one
filter will sequentially 'slug the second filter. It is VASTLY more
efficient to run a recirculation / polishing system INDEPENDENT of the
in line fuel deliver line as a high turn over recirculation filter will
VASTLY 'turn the tank over' much quicker )3-4 gallones per minute) than
an in-line filter (1 gallon per hour average). The advantage being
FASTER tank recovery back to 'normal' particle background .... using a
filter retention of approx 10 times the retention of the final filter
in the direct feed system. A 'techy' would call this the laws of
exponential decay PLUS the 10X retention filter does have an
efficiency (although low) at much smaller than the 'rating'. Since you
'turn-over' so much faster though the larger retention filter (with 10X
lower flow resistance) the net result is VERY fast clean up of the tank
contents.

Send me an email at RhmpL33(AT)att(DOT)net for a sketch of my
filtration train ( independent recirc. plus blocked and bypassed dual
parallel direct line filters .... plus on-line reserve (emergency) day
tank.
The day tank is a gravity feed 3 gallon 'storage' medium for clean fuel
.... so that if all hell breaks loose I can simply switch it IN to the
direct feed line and run for several hours .... and dont have to worry
about changing the diaphragm in the lift pump, could care less about
changing racors, etc. etc. etc. until 'things settle down'. I dont
know about you but usually a heavy sea state will knock crap loose in a
tank ... and thats NOT the time to go below and screw around with
'filters' - when the sea is running hard, if I put my head into the
bilge for any length of time ... I power -puke.
