Starting a diesel that sat for 18 years.

I've read the threads under this heading and found one similar to our situation:

We bought a boat that has been sitting on a trailer for pretty close to 18 years, best guess. Never registered, never been in the water, engine hour meter shows 1 hour running. Its a Norsea 27 that needs the interior finished.

The engine is a Yanmar 2gm20F, our very first diesel, in fact our first inboard.
I can see fuel, the color of weak tea, in the filter bowl. Here is my plan to start the engine :
1: change oil and oil filter
2: drain fuel tank
3: change fuel filter
4: drain as much of the fuel in the lines by opening the bleeder valves
5: disconnect steel tubing to injectors, attach vinyl tube to steel injector tubing, lead other end of vinyl tube to container to catch old fuel when engine is cranked. Maybe this is a bad step if the pump requires some sort of back pressure.
6: supply fresh fuel to fuel filter intake.
7: bleed system
8: decompress engine, crank till fresh fuel is visible in vinyl tubing.
9: reattach steel tubing to injectors, supply cooling water to intake, close decompression level, cross fingers and crank engine.
10: hear engine running
11: do victory dance.

Is this the right plan? Am I being overly cautious or not doing enough?
