Thanks for sharing all that learning. I am also contemplating the silicon hoses
and I have the add on carb heaters which require coolant water round their
jackets.
Do you have those too and if so do you need extra hose to connect those
or is there enough n the kit?

jus have a single hose from the turbo to the airbox.

The rubber are not more sturdy. They will degrade over time and MUST be
replaced on a regular basis.

screw clamp and tighten it fully when cold when the engine warms up, the fixture
expands and forces the hose into the screw clamp. This causes eventual cutting
and failure of the hose. If you adjust the screw clamp when the engine is
warm, then the fixture shrinks when it cools, it becomes loose and leaks. The
spring clamps are constant tension clamps which account for the expansion and
contraction of the fittings keeping things properly tight.

to get at the hose fittings and then reassemble things after the hoses
have been replaced. I'd bet that the disassembly/reassembly takes longer than
the actual hose replacement which is pretty quick, half hour to an hour maybe.
Since I'm not familiar with your aircraft and engine installation, I can
only make a very wild guess as to how long the disassembly/reassembly might
take.
Probably you could accomplish the total task in 1 or 2 days if you are very
good with tools and have everything you need at hand. Is there another
Europaphile
anywhere near you who has done this task and could assist you. Probably
make things go a lot quicker.
