While the Hewitt industries EMP install hose is a quality part, I don't recommend it for the TDI's (at least not for the ALH).
I tried to install it today and it is about 6 or 7 inches too long, and not long enough to make a loop back to the firewall. The hose is also very stiff and does not like to do any bending.
I tried to find 1/8" stainless steel tubing but could not find any local.
On my way home I had a bright idea so I stopped at an AutoZone and picked up a 3/16" inverted flare steel brake line and 2 fittings to adapt from the inverted flare fitting to 1/8" NPT thread.
All together the brake line and 2 fittings were less than $11, I also needed a 1/4" to 1/8" NPT bushing and a 90 degree 1/4" NPT street elbow.
Everything went together very easily and I used a rubber cushioned metal clamp to hold the line using the same bolt that holds down the turbo oil feed line to the exhaust manifold.
Here are some pics of the install:
