Daniel,
I suspect you've got at least 2 problems: The melted brake switch
would seem to point to a short somewhere in the brake light circuit.
Check the wiring, the bulbs, and the bulb sockets. My guess is that
high current draw thru the switches caused them to melt.
It's also worth knowing that high current thru these wires often
causes the insulation on them to look "corrugated" because the heat
causes the insulation to swell and get oversized.
>From your description, it sounds like this happened sometime just
before you smelled that bad smell, like when sitting at a stop light
with your foot on the brake.
It's possible that the melting progressed just far enough to short
the hot terminal of the switch just as you happened to try the L turn
signal. They are different fuses; which one blew?
As for the leaking gas tank hose, there should be a sort of wide
rubber band under each end of that hose, over the metal pipe
underneath. That band is often damaged if the tank is removed and
people don't realized that it is necessary. In your case, it may be
missing or it may be torn or cracked.
You will NEVER get those connections to seal until you have those
bands in place.
The bands are hard to get installed right, and they need to be
installed exactly right. They have to cover the "hump" in the pipe
and they need to be flat and not folded. I have the best luck with
them if I glue them in place on the pipe first and let the glue dry
before I try to install the hose. Use rubber cement or a good gasket
sealant.
Replacement bands are available from a VW dealer, as they were also
used on Beetles of the same era.
