Yes, Karl and everybody else, this is quite a bit of wit and wisdom,
and, though not the most dexterous way of repairing this fuel leak, it
worked so far. I did relieve the fuel pressure, removed the injector in
question and slid a rubber (heater) hose over it. The leak is gone, and
there was no damage to the rail or anything else. The only problem: This
would not pass the "DM" certification if old Doc Tim had his way. At
all.
So how do I replace that rubber at the injector??? VW dealership told me
I needed to buy an entire outfit of an injector: $106.00 +tax, a-ootch!.
Karl mentioned a 6mm high -pressure hose, but do you just slide this
over, too or what? Cause I don't see how to remove and replace the stock
hose, which seems to be glued to the injector body. Any help
appreciated. Really.
