Colored hoses, Are they still available? Or has anyone tried dying a hose? Options

[TonyA]

Maybe i ma crazy but are these available anywhere, or has anyone ever attempted to bleach and dye a hose?

out of interest, does anyone know if the 1.8s originally had coloured hoses.
or did they switch to uncoloured hoses with those?

i think, and i mean i think, because it could just be you want to see it, that the vacuum lines on my distributor looked vaguely green still, before i replaced them last year, but it might be because i wanted to see green. if it was there it was so faded it was grey i saw green in. the rest of the lines were faded grey. and as far as i remember even when i bought the car they were grey color (31 years ago). i don't think any lines were replaced before i got the car in 89. but again maybe my memory is wrong. coloured lines were not something i knew about back then. they might have been a very faded red i thought was grey.

red as a color in any form, paint etc, fades fastest of all colours.

as to availability off the shelf, when you go to porsche themselves, where we sourced the new replacement hoses, its just black (or dark grey) hose. we went to porsche to get them given we are in aus - turned out to be easiest and was surprisingly, good value.

@wonkipop Being an original 1.8 owner, the only colored lines on mine are green, to/from the vacuum canister. No red hoses. If you'd like, I could post a pic.

that would be great starbear, thanks mate.

yes, i've double checked mine and all i have is the one green line from the distributor, which we ended up keeping because porsche were unable to supply the size of hose.
i didn't realise but my mechanic cleaned it right up and checked it before he put it back on and its looking really green again.

but i have some other questions i will compose myself to ask specifically in relation to 1.8 vacuum hose arrangements and you might be the man to answer them.

@wonkipop I stand self-corrected; looks like I have two green hoses. The first is off the vacuum cannister (passenger side) going to the throttle body (front side); see photo. The second comes off the T branch into the air plenum; see photo. The first I'm sure of; the second may or may not have been swapped out just because I had that size hose. I've also attached my hose diagram; the first is Line 4, the second is Line 10. This diagram varies slightly from Jeff Bowlsby's and Automobile Atlanta's diagrams; perhaps as Porsche modified things throughout MY 74, probably for emissions, it seems like the hoses and layouts changed.
With this arrangement, "Frogger" has been running flawlessly; if anyone sees obvious error(s), just let me know - always willing to listen to those more expert than me!
Hope this helps!

Awe crap! Looks like I painted the wrong vacuum hose green. I colored the advance line rather than the retard. Anyone know which hose was green for 73 2.0L D-Jet? Your pics also confirm that the green paint I used is too bright. I might need to try mixing in some white for a better match.

It would be cool if colored kits were available again but with the method I used, it is just a $10 bottle of paint and a cheap sponge brush. Super easy DIY project.
