It took time for it to leak out of the boat and it seemed that it was just a continous leak. If you have to drain the tank just by some 5 gallon cans, disconect the fuel line from the motor, stick the hose in a can and pump the ball to get things flowing. It takes some time so just keep an eye on the can nad change them out as needed. Also the last can of gas take it and shake it up and dump some into a jar and see how it looks. I found my last can was pretty dirty and had some water in it so I did not put that back into the boat.

Thank you sir. Check all connections to and from fuel cell first.

Welcome to the site & congrats on the new crew member. These are great boats for families. I have an 83 cuddy, did you take off the inspection plates and check the fill hose and vent hose that is in the forward deckplate, the rear one is where the motor connection is and the guage sending unit. My fill hose was rotted and it only leaked gas when i was filling it up. you can check that aand not have to pull the tank cover...

FWB, go to the Modifications forum and look under Hey Whatknot. on the 2 page he has a good picture of what the top of the tank looks like with the deck removed.

For my tank leak (85 cuddy), I turned off the valve on the fuel pickup. The boat was sitting in my driveway on a slight slope so that anything in the bilge would drain to the stern. I plugged it and checked it two days in a row (draining in between) and found fuel in the bilge each time. Since my fuel line was shut off I reasoned the tank must be leaking. The fill and vent hoses are on the top and the tank was not full so there would be no way for a leak to occur there unless it happened when filling the tank.

Sure enough, after removing the tank I found a hole the size of a dime and several other areas with active corrosion that would have leaked soon enough. I am one who bought a 40 gallon from greatlakesskipper on Ebay and it fit nicely in my 85. I have yet to do the final install but it slid right in there.
