Hallo again,
1990 VW Fox wagon when you first start it in this zero/sub zero weather lately. There is petrol dripping off the bottom of where the fuel pump and fuel filter is located underneath the car.
Once the car warms up lets say 10 minutes it stops and dries up and not a drop comes out.
Unless the car sits for an extended period of time or overnight it won't leak again all day.
It's almost certain a rubber fuel line that needs to be tightened. To my amazement the clamp that needs to be tightened is facing upwards towards the underbody. Shoddy work as I had this fuel pump replaced and filter not that long ago. Once the clamp gets oriented correctly and tightened I highly doubt it will leak again.
Question? Why does it leak when its first started in the colder weather and then stops?
Your suggestions much appreciated regardless.
Thank you!
Best, Raphael

I know Suburu had a recall of a similar problem. It turned out to be a specific hose or part that was special and required about 2 weeks to get the part in. It seems the issue in my case is more simple like a new clamp/hose or changing the position of the clamp. Seems like the extreme cold shrinks the hose just enough so when the VW is started the pressure built into the system forces the fuel out. This won't leak unless the VW is started and the weather is extreme. Went out tonight and it's -2 below and the cardboard I placed under that area was spotless and the hoses and entire area was dry as a bone.

Lousy workmanship from whoever did the job.
True and sad cause I've paid these folks mucho dollaros to do this and other work. But that is going to change from now on even if it is diffcult to find mechanics that know how to work on the VW Fox.
