I've run Diesel from 55USG Drums filled during WWII, with no problem,

Interesting. Were those drums sealed all these years? I wonder if WWII
diesel (different stuff than we have today) sealed into drums with the
intention that it would be stored for a long time would give the same
results as modern diesel that's been sitting in 3/4 to 1/2 full drums in
the
sun for a few weeks.

My original comment about drums was really just shorthand for the reports
I've received about poor fuel quality up in Newfoundland where the fishing
restrictions have slowed sales to the point that stuff which is a long way
down the supply chain anyway gets pretty funky. There were a few problems
here in Maine this summer simply because the long hoses at some marinas
would grow stuff when no one came along for days to buy due to the high
prices earlier in the summer.

Sealed Drums, filled in 1944 by the US Navy. Straight #2 Diesel, no
addatives or other crap. My Tank Farm has 250K USG of Diesel #2, and 15K
USG of Diesel #1 in it, and after a winter, we get less than 40 USG of
water out of ALL 20 Tanks. Never had to treat ANY of the Diesel with
Biocide, since we switched to receiving our fuel in 6000 USG
Over-the-Road Tanks on a Freight Barge, rather than from the Fuel Barge
with Sea Water Ballasting, and that was 20 years ago. I still keep a few
of those Navy Surplus Drums of fuel around for emergencies, as it is
KNOWN GOOD Fuel. RaCor filters are a wondrous thing, I use them
exclusively, both for the Winter and Summer Powerhouses, as well as on
the lines to the Fuel Dock. Never had a problem with ANY of the Diesel
Fuel System. Now the Gasoline Stuff is a TOTALLY Different deal......

Huh? Diesels do not run "lean". *Hint, think about you control
power/speed in a diesel.

Just one of a few of Capt. John's misconceptions......

You need to study up a little, try asking your engine manufacturer
about those filters. The marine specialist at HO Penn, our local Cat
dealer on Long Island, was adamant about this. Said regardless of the
engine manufacturer, they specify the 30 micron filters for a reason.
Your probably more likely to get away with it with a little sail boat
engine than a larger high output engine. For the price of a rebuild,
or replacement, I'll take the manufacturers advice over your's and day
of the week.

Your ity bity KittyCAT Diesels don't even come close to the BIG YELLOW
CAT's in my Summer PowerHouse. (2.8 MegaWatts worth) Our CAT Service
Folks spec'd and installed MULTIPLE Racor 2020 10 Micron Primary Fuel
Filters on the 4" fuel line that feeds the PowerHouse from the Tank Farm.
The PowerHouse was Designed by Ed Wahl, one of CAT's most repected Power
Generation Engineer dudes, who taught a whole Generation of CAT Field
Service Folks how to do their JOBs, being the CAT Power Generation
Engineering Instructor, in his later life.

If your running your filters until the engine is getting "Starved for
Fuel", and "running lean", then your and absolute Moroooooon, (Bugs Bunny
Definition) as that would mean that there isn't enough fuel to fully
fill the Injectors each time they fire, AND that also means that there
would be NO fuel coming back thru the Fuel Return Line, AND consequently
No Cooling of the Injector Tips, which is the Primary Reason for the
Fuel Return Line, in the FIRST PLACE. Very Good way to BURN OUT the
Injector Tips on your CATs, Sonny.... Just where did you learn your
Diesel Engineering.... Dufus's R Us???
