Bladder or smaller poly tanks?

[O C Diver]

It's 40 years old and my insurance company probably doesn't care. It's liability only.

I could be wrong, but a liability only policy puts them on the hook for environmental damage if spill fuel overboard.

Correct. There is just no inspection or survey for liability only.

But not getting environmental protection insurance, while not often needed, could be a costly mistake.

SPtanks will install an access manway and weld a new tank inside your old.

as a follow up to this thread I have cut out my old steel tank and painted that engine room area. I ordered 2 50 gallon moeller poly tanks an am debating how to hook them up best... maybe I shouldn't have made a new thread but here it is in the power systems section:

I would work out a way that only one tank at a time would be filled.

The empty tank will not gather condensation , and could be usedonly when needed for range or winter heating.

If you love bestitis , if the upper tank could be used as a gravity feed day tank , it should add to the value of the vessel.

Installing plastic tanks takes time , as the virgin tank must be filled with diesel to let it expand for a couple of days , then secured in.

Pro boat builder will explain the required techniques.
