78 refresh questions:
1) http://www.autoatlanta.com/porsche-p...section=105-05
#44 and #45
What hose do I need to obtain to fit these?
2) Same drawing, what hose now replaces #46
3) Where do I find 2.5mm vacuum hose for the top end/egr functions? Not silicone.
4) http://www.autoatlanta.com/porsche-p...section=105-05
What do I use for #27 and #33?

If you're concerned about getting close to correctness this is what it all looked like originally:
44 and 45 are NOT molded but had this weird slow spiral seam in them. Appropriate size water hose is fine and these guys have nice stuff: https://belmetric.com/hose/
They also got Vac hose down to M3 which works fine on all this stuff.
The molded hose going to the rad is a molded hose, not spiraled. I've only used "used" ones but there is room to make the turn with a straight hose..(not as pretty)

They dont have to be "correct" just the right size...that radiator vent hose..ya..tough one.
Helping a friend refresh a very nice mid year '78 rescue...well, nice, all thing considered, and it's survival story.

My solution to #46 (which was missing in my car) was a molded elbow hose trimmed to fit, and an inline coupler to some bulk hose.
Not at all concours correct, but it is functional.

What do I use for #27 and #33?
- #46 available thru Porsche (later model cars) but not long enough to do 44 (by an inch or so - insert curse here)
for 44 and 45, I used bulk hose
- i yanked the EGR and it’s 6 or so vacuum hoses. Very happy with how it runs but I don’t have to deal with Cali smog.
