Thanks for the info and offer. I'd appreciate any photos you have. I haven't started this job yet, although I just bought a heater so I can work through the winter.
One issue I have is that the original owner fitted a pneumatic fuel
gauge system, and a couple of years after we took ownership
the sender -> gauge tubing turned brittle and fell apart. I stupidly didn't plug
the sender, so after a few fill-ups we had diesel
on the top of the tank. From what I could pull out I believe there was some woven material on the top of the tank (which was now saturated), and I'm pretty sure the bottom of the galley sole is saturated to some degree as well. So I have some motivation to rip it all out in the process of replacing the tank.
Our galley is highly non-standard. We have a locker where the stove would normally be (gimballed, outboard). If you're facing that locker there is a counter to your left, along the bulkhead that separates the galley from the table below. On your right, along the bulkhead that separates the galley from the aft cabin
is the sink, and then then furthest inboard, a fixed 4 burner stove with oven
above. Although it seems counter-intuitive, my wife has never complained about the lack of gimballs (and has never had anything spill) in the 23 years we've owned this boat.
Anyway, photos would be greatly appreciated!
