Taking the tank out

'Tarka the Otter' has been out of the water for 6 years. Everyone told us we must remove and clean the fuel tank.
I read up on several ways to remove the tank. In the documentation that I received from the Coghlans I found an instruction sheet written by John Stanton Marine Services (May 1982). It recommended leaving the inspection plate on, removing the plumbing  from the plate, and disconnecting the fuel fill pipe from the deck filler.

If I had not needed to empty out a full tank the whole procedure would have taken 45 minutes.

I disconnected all the plumbing from the plumbing plate on the tank. There was a joint in the fill pipe underneath the cockpit. I disconnected the fill pipe there. Normally it would be disconnected at deck level. I rigged a block and tackle to a beam across the companionway.
I then attached a slip knot onto the neck of the plumbing plate. I then gently pulled the tank up with the block and tackle. 
I moved the tank aft and put another lasso around the forward end of the tank and slipped it as far aft as I could. I did this by reaching under the tank and tugging the line forward.
I attached the block & tackle to the lasso. I pushed the tank as far aft as possible and hoisted the forward part of the tank up  all the while pushing the aft part down. The fill pipe should pull forward.
Disconnect the fuel pipe and the tank is free. In my case the fuel fill pipe had broken. It was rotten. The picture was taken just after it cleared the sole. Notice that the hose clamp is missing as well. The sump needs to be cleaned out. A real mess.
