The fittings on the tank are pipe on the hose end, at least for new fittings.
Also, if you go with Trident hose, which is very pricy, you can get the 1 1/2 hose  in 12 lengths which is much cheaper per foot and should be all you need for a MK1

Took me about 6 hours just a few years ago to just change out the hoses that go from the through hull up to the Y valve, the Y valve, and the hose from the Y valve to the toilet.  Honestly, if the door to the underside of the sink was double in size, it would have been a piece of cake, but getting that Y valve off that aft wall under the sink is terrible.  Once that was off, it was easy to get the hoses off.  taped up the ends and took them in to West Marine to make sure I was getting the exact hose.  The reverse process to reinstall.

Everything already covered except automotive tailpipe expander
It makes attaching the heat softened pipe to the barbs a lot easier

I can see how that would help.  Great idea.  But I question weather the expanded hose would shrink back to original diameter.

I use an Uponor Pex expander gun to stretch my smaller hoses when attaching them.  The only caution I'd provide is wire reinforced hoses.  It seems the wire becomes a bit dislodged in the hose when stretching them.  That said, I dont have any leaks where I've used the expander on a hose.
