[Vwdiesel] RE: [Audi-VW-Diesels] Fuel return line

[James Hansen]

Gotta watch that Adrian.  Some model aircraft tubing is silicone tubing meant
for alcohol- nitromethane not diesel.  Diesek will eat it up after a while I
think, maybe try a bit first, or if you don't have any, lemme know, I'll drop a
piece in some diesel and let you know the results.  I know it isn't recommended
for diesel model A/C engines, you are supposed to use neoprene.
