why?
it could/should last as long as the boat as long as we dont go biodiesel....
I hope you are correct.
Stainless steel isn't ideal for fuel diesel fuel tanks...much rather have fiberglass
There were a lot of gas powered boats that had fiberglass tanks that failed due to ethanol. However we are talking about diesel and diesel doesn’t have ethanol in it so fiberglass is a great material for a diesel tank. We had a custom fiberglass tank built and installed in a previous boat. It was great. No corrosion problems ever.
Black iron?
The tanks on my N46 were black iron.
#1 fuel tank material is MONEL, but its pri$y.

On MOJO we use a Gulf Coast "paper towel" filter for a primary. It's plumbed so we can easily switch to a back-up Racor 500 if needed. But since installation of the Gulf Coast Filter, having burned over 5,000 gallons, the Racor not been used. The Gulf Coast filter reportedly provides "sub-micron" filtration. I have no way of measuring it other than to say a few years ago I cut open the on-engine filter to see how dirty it was... it looked essentially new! We can also recirculate fuel from any one of 4 tanks back to any other of 4 tanks, and transfer fuel from tank to tank. I circulate my fuel to polish it once a year, circulating each tank for 24 hours. I drain the water (never much) annually and change the roll of paper towels maybe every 2 years. It's been a pretty much bullet proof system.

As a former boat builder, that cluster F would never happen on one of my boats.
Here is a link (Tony Athens Seaboard Marine) that may help you out with the overall concept of fuel systems...it may be similar to what another posted before....

You are far less likely to spill with the squeeze bulb setup. Button the new filters up and pump.

Given your experience as a former boat builder, do you have any constructive comments/information that you might add to help inform the rest of us and increase our own knowledge?
First, when the captain is incapacitated, the least knowledgeable person on the boat needs to be able to figure it out in the worst weather. There are plenty of examples that have been previously posted that are very straight forward and labeled. Keep it as simple as possible.
