Those zip ties look a little tight.  May work fine but I don't like it.
You can get wire separators- one example is here: http://tinyurl.com/33habhr

The grey cover on your fuel lines is for abrasion resistance.  For this you
can simple use heat shrink tubing on your new lines.  Ebay sellers have it
in bulk for cheap.

Subject: 2.1l Spark plug wire routing

Hi,

I have a 91 Westfalia, standard, 2.1l.  I have just started to do the
work on it myself after having work done by a mechanic for the last
couple of years.  My work has slowed down to a point where I can do
things myself and take the "right".

I have started with things that I'm familiar with from days of old,
though this is my first fuel injected vehicle I've worked on.  So, I
started with rotor, distributor cap, plug wires and spark plugs.  I
wanted to know the "vintage" of that system and in the grand scheme of
things it's not that expensive.

I routed the new spark plug wires where the previous ones went.  After
it was all tie wrapped, I noticed the plug set came with directions, so
out of curioisity, I actually read them!  lol  It says to keep the spark
plug wires separated as far as possible, and if they do need to cross,
it should be at 90 degrees.  Well, the spark plug route that I followed
for the passenger side cyclinders doesn't conform to that policy!  I've
driven this van with wires like that for 3 years now...  how important
is this "guideline".  It makes sense from an inductive interference
point of view...

Where would the plug wires normally be routed?

I've got a photo of the setup here:

And yes, the fuel lines are next... but I'm curious if these are "stock"
VW fuel lines with the grey protection on them?

Thanks,
