On the hottest day of the year, I tackle the sunroof drains...sheesh
In looking at Peavey (TSC) for fume lines for the bug's fuel tank, I found some vinyl tubing for the GLI's sunroof drain tubing, seeing as the old stuff looks dried out and is too short in the back of a Jetta, remember the roof is from a Rabbit.
I measured the steel outlet tubes at 7/16" and should've stuck to my guns and bought that ID size. I bought 20' of 3/8" thinking it would stretch, It did but not stretch enough to push them on more than 1/2". I backed up the interference fit with a twist of lockwire for security. I used about 18' of length overall, running the rears deep into the fender. Make sure you clear out the drains in the bottom of the fenders or its gonna cause problems.
Fishing was a challenge, as I initially fished the pillars with wire. I ended up using a length of plastic tube (that was formerly the vapour lines from tank to filters on the Jetta) as it was rigid enough to fish and allow the tubing to follow over it.
It might've been a pleasant project...if it hadn't have been 32.5 deg C!!!
Advice; pick a 25 deg day, use 3/16" hard plastic rod/tube for fishing, and buy 7/16" ID tubing, it would've gone much better!
