I have a continuing fantasy about owning a 32'-38' trawler. One of the
common problems in a vessel of a certain age and price range are leaking
diesel fuel tanks. The proper repair is to pull the engine (the tanks
are generally on either side of the engine, requiring getting the engine
out of the way), and replace the tanks. The cost of doing this
approaches the price of the boat. Is anyone aware of a reliable method
of tank repair in place?

Sure. Weld in repair panels OR CLEAN the interior of the tanks very well
and epoxy coat them inside. You can buy fuel liner epoxy at many marine
stores.
But you are NOT going to do either with the tank in place on a 36
foot trawler, I'll bet.

The tanks will need to come out, one way or the other, unless you put
in a bladder like is used in some race-cars and some aircraft tanks -
with the fuel take-off inserted from the top.
