Why is it that Marine Fuel Tanks, never have a Water Trap Drain, in

deal with this type of stuff if they did. Just open the valve and
slowly pump out the bottom 5% of the tank, thru a 10 Micron RaCor
and be done with it for the season. Not Rocket Science, just smart
Engineering. Simple, easy to do, and effective. You don't really even
have to have a valve on the Trap Line if you use it as a
"SightGlass/Vent" and have it plumbed up a couple of feet above the Tank
Top.


Because the USCG in all it's wisdom says that you can't have a valve
on the bottom of the tank and all tanks should be suction from the
top. Lots of other jurisdictions are o.k. with the concept of a sump
on the bottom of the tank for just this purpose

FEDERAL LAW

183.518 - Fuel tank openings

Each opening into the fuel tank must be at or above the topmost
surface of the tank.

Ok, if they are that "****y about it" why doesn't the Tank Builder,
design the tank with a Water Trap along the lowest place in the tank,
and then build a 1/2" pipe that goes out the top of the tank, who's
bottom end, is 1/8" above the bottom of the Water Trap. Then all one
would have to do is use a Postive Displacment Pump in that line and
suck the lower 5% of the fuel out, thru the "Polishing" System, and
back into the tank. Again, this isn't Rocket Science, and even an
USCG Ensign, fresh out of the Acadamy, could see that qualifies, under
the cited Reg........ Sure beats "Screwing" around with Commercial
Tank Cleaners, ect, and wouldn't cost "diddley" when the tank was being
built......

Bruce in alaska What USCG Genious thought that one up......
