Hi,
I'm in the process of replacing an old rust cast iron tank in the aft engine
compartment. It is one of two on the port and starboard sides. The other
one was replaced before I bought the boat and is in good shape. (stainless
steel, 40 gallons.) I want to know if there is another type of tank that is
better than stainless steel. I know plastics/polymers have changed alot in
recent years. What's the best way to go and why? What are the costs?

Thanks

Excluding monel (very $$) - best diesel tanks are said to be alum -
not s/s a the sulphur in diesel attacks the weld areas in the tank and
can cause pin hole leaks.

S/S is best for fresh water tanks.

I agree on the comments about S/S and diesel, a NO-NO.

Aluminum would be the logical choice for gas or diesel in a custom built
tank. If your not restricted to an unusual tank shape, there are many ready
made plastic tanks available upto about that capacity. Tempo comes to mind..

Personally, I wouldn't want to store gasoline (long term) in plastic tanks.
