Weather warmed up here in UK and so has my fury with a simple task that has burned a whole damn day - the rear heater hose from the valve to the heater core bottom connection. I thought it was because it didn't pass through the hole in the heat shield on the bulkhead but a tape measure sasys it isn't long enough to do so without restricting flow where the pipe bends.

Absolutely nothing I have tried will keep the damn thing off the back of the engine, it also fouls the AC expansion valve at the other end so either the pipe I have is thicker than the original (can't find it) or something is amiss.

It is a new hose that I'm trying to fit, I don't think it is OEM, not sure whether OEM is actually available thouigh SNG do list it for crazy money so perhaps it is still available.

I'm tempted to buy the genuine article - cac2917 - but would be even more annoying for it to demonstrate the same behaviour and I'd blown money on it for no reason.

I'm pretty sure much of the car is afterthought, things weren't really thought through - would be so much easier if the whole engine sat around 50mm further forward for so many things.

The hose should run under the aircon and then up to the tap. Manners have got them and they are cheap!

On your behalf I have just taken a peek at my car and the hose does just touch the B bank head but it is on a flat surface and seems fine! It easily clears the aircon valve running under it.
This is the hose you mean I take it?

 

I remember my car looking like that not so long ago ...

Yep that's the hose, I've been trying to keep it off the head but I guess I could put something around it to counter abrasion. Where mine is touching the expansion valve is on the capiliary, underneath there is as you say tons of room - it is the vertical piece up to the valve, it isn't tight but could be when the hose has pressure in it another 5mm in the horizontal across the bulkhead and it would be fine, even better if the heater connection itself was about 5mm shorter (not the hose but the heater, can't find my old one but I'm sure I haven't thrown it out.
