Had a similar experience to Gary when I repowered my 38 in 2010. Had noticed diesel smell, but could not find any leaks in the lines or fittings. While the engine was out I pulled the old tank to get access for another project and discovered several pinholes in the bottom of the 20 gallon aluminum tank where it sat on the plywood platform and moisture collected. I guess I wasn't too surprised or disappointed in finding the leaks - after all, the old OEM tank had been in place for 35 years.
I replaced the old tank with a 22 gallon monel tank that had come from a gas powered boat that had been converted to diesel. The tank was cheap and it fit on the platform. A local machine shop added a fitting to the top of the tank for about $25, so the whole experience was pretty cheap - probably under $100. I went to Lowes and bought a small sheet of neoprene (maybe 4"x6"?) gasket material and made some 1" square rubber pads to put between the new(ish) tank and the wood platform. And, BTW, both my OEM tank and the monel tank had a threaded collar in the top for a 1 1/2" pipe fitting. I put in a 90 degree elbow th handle the transition from horizontal hose to vertical fill.

Last year, it started weeping - small leak I couldn't find. Pulled it out and found a whole bunch of tiny pinholes in the bottom where it rested on the plywood. _______________________________________________ This list is supported by the generous donations of our members.
