I also have a 1978 with a Yanmar YM30. When I bought the boat last summer the tank was leaking. After pumping out the fuel I pulled the tank and found about a half dozen pin hole leaks under the rubber lined hold down straps. The tank was Monel. I had a new aluminum tank made for it by Luke in RI (did a great job at a good price). After 38 years I dont think the original tank owed me anything (got a $1,000 price reduction from the seller that covered the cost of the new tank and labor to replace it). One thing I did differently was I replaced the 30 gallon tank (originally sized for an Atomic 4 gas engine) with a 20 gallon tank. Same footprint, just 6-8 inches shorter. Now I have plenty of room to work on top of the tank to get to the various fittings and the 20 gallon capacity (think 1 gallon per hour chugging at 6 knots) is more than I need for harbor hopping in Long Island Sound.
