"melting" fuel lines on '83 quattro coupe
This may be a known problem but it is new to me and it is turning out to
be expensive to resolve . .
Recently I found four (of the five) lines that go from the fuel
distributor to the fuel injectors were literly melted away.
After a great deal of head-scratching I discovered that the ground lines
from the engine to the chassis were weak and could not support the
current output from the alternator (when under a heavy load). The effect
was that the steel braded covers over the plastic fuel lines were
completing the ground circuit and acting
like heating elements, thus, melting the plastic lines. (Yikes, a fire
The solutiong has been to add a supplimentary ground line from the
alternator to the chassis. I picked one up at my local autoparts store
form about $3. Unforturately, the replacement fuel lines from my local
Audi dealer are about $50 a pop. Of course, some of them are coming from
the old country so there is a 4 week wait . . .
