Ron

Google  RCI filter

Hey  Ron, I dont know about these things. I'd be concerned because the
smallest unit  is rated 0.5 to 15 gallons per minute. That says to me that the
innards likely  don't work well below 0.5GPM. Who has a trawler that has a 30GPH
flow rate?  The  Racor 500s on our 4-236 Perkins do not stop all the water - I
have found  water in the secondary. I don't think any of these filters work
well below a  certain flow rate - which is below what most of us have.

Who sells and how much do they cost?

Dear list,

I have looked at their web site. What i like about them is that there
are no filters, so that is a plus.

But, in all of their marine installations, I see one RCI installed.

Most(?) Racors are installed with dual elements, water indicator, and
vacuum.

So, if one was to use these, one might consider piping up a pair,
switchable on the fly.

If one's fuel delivery rate was at the RCI's limit, one MIGHT
consider getting 2 pair of the size that is at the limit, just to be
sure.

One MIGHT consider doing this especially if one has one of those new
fanged HPCR Tier 2 diesels...

Especially if you are the person who believes that the engine mounted
fuel filter should normally die of old age, and not due to clogging....

Now, we are talking $$$$ and some added complexity.

But, IMHO, Racors are considered the norm, the Cadillac, the in-line
filtering system all others appear to be compared against. If RCIs
were the better mousetrap, then the world (at least the marine world)
would be singing their praise to high heaven, don't you think?

Now, please do not get me wrong. There is probably a place for these
devices in the grand scheme of things. Just need to make sure that
one is comparing apples-to-apples....

I believe NOT everyone needs Racors. If you have a smallish fuel
tank, fuel up frequently, do not venture too far from the coast, etc
etc, then you probably do not need the whole hog Racor installation.

But, if not in the above category, then you have some research to do
and decisions to make.

I personally like a separate high speed centrifugal purifier. In
port, could purify engine oil. When not doing that, can purify the fuel.

Underway. can use the purifier to fill the day tank.

Probably will not go this way, but would really love to....

Who has a trawler that has a 30GPH
flow rate?

Remember John, on many engines MUCH more fuel is pumped than is burned...and
just returned to the tank. I am told that cooling the injectors is one of
the functions of the extra fuel flow.
