An interesting thing about the Yanmar 2QM series is that there is no return
line back to the tank. Evidently, the injector bypass just circulates back
as far as the injector pump on the engine. It is an unusually cool running
engine for a diesel so maybe that helps avoid the fuel getting too hot.
Flow through the filter is whatever fuel consumption is.
Just out of curiosity, I'm going to look at recommended flow rates on some
separator filters but I'll be surprised if any
go as low as 1 gph. It's appears to be a centrifugal process judging by the
spiral grooves I see on some of the filter housings so it must take a
reasonable flow. Just out of curiosity, I'm going to look at recommended
flow rates on some separator filters but I'll be surprised if any go that

Chris had a good point, now that I'm putting an emulsifier
(StarTron/Soltron) in the fuel, The water isn't going to separate out
anyway.

Quick Question: Just where oh where is the water going to go to?
Emulsified out of existance?

I'm getting into your fuel problem a bit late Roger, whats up?
You got alge problems?

How long has the fuel been on your boat?
How many gallons do your tanks hold?
What are your tanks made of ?
Do you have access through an inspection plate?
Tanks baffled?


In the USA the major source of water in your fuel is condensation of
the moisture in the air in the tank, collection on the tank top then
dripping into the fuel. Best way to keep moisture out with the boat
sitting most the time is to keep your tanks pressed full.

Alge killers present thier own problems and none do a proper job IMO.
Your options are to slosh out the alge and buy filters by the case
until it's all gone, or clean the tank. Once I picked up a 120'
crewboat that had been in Mexico for 3 years and had the worst alge
problem in a fuel tank that ever existed, so bad the water traps would
not drain due to getting clogged with alge, had to poke the drain
spigots with a hanger wire to break the crap up to drain the water. We
used up a couple grand in filters before we got it cleaned up, we
burned 180 GPH, with a 4000 gallon tankage. The boat had aluminum
tanks that were the deck in the passenger area that was always kept
cold, the boat rocking and sloshing allowed the tanks to breath in and
out moist air all the time, creating massive amounts of water due to
condensing on the tank tops.

So what's it like to go that deep under the ocean?
