Last year I had trouble with dirty fuel while on a cruise to Maine.  I stopped at the Great Island Boat Yard to have the old fuel pumped out and the tank cleaned.  The mechanic pulled up the board in the quarter birth and, after asking how full the tank was, without hesitation opened up the sender.  He used a 12v battery powered pump to pump the old stuff into a five gallon bucket which was brought up to a recycle point (several times).  The hose going into the tank was a flexible one, and that was good as there is in fact at least one baffle down there.  The flexible hose was able to get around the baffle though.  Once the fuel was all sucked out the mechanic was able to shine a flashlight into the tank, take a good look and proclaim the insides “shiny bright and clean as a whistle”.   I have had no fuel problems since.

 

As for the fuel flowing out when the sender cap is removed.  Yup, that can happen.  If your tank is full, and especially if you suspect it’s so full as to be in the filler hose, don’t pull the sender.  Besides doing it as Harvey describes you can use the same method and tools that would be used with the sender cap but suck a few gallons out through the filler hose first.  Then pull the sender cap.  By the way, you might as well check the sender at this time.  Three years ago I replaced mine, and the old one was so corroded it just about fell apart as I removed it.

Hi Jeff,

I'll save Don Brooks an e-mail and provide his own solution to the  cleaning of the C-27 fuel tank.
I believe that the tank is not level and by using the sender opening you may not get the true bottom on the tank which is the  forward port side of the tank where the fuel outlet valve is located.
This  is where you will get  whatever water and gunk is in the tank which settles to the bottom. 
You might get to this spot using the sender opening by using flexible tubing, but my guess is, (let's hear from the list) there is probably a baffle in the way.
As a precaution, if you have a full tank, you can can disconnect fuel tubing at the engine fuel filter and let the electric pump pump it out. (then bleed the fuel system).

Also if the fuel outlet tube has a screen on the tip and you have a primary filter, the prevailing wisdom is to take it off.
