[Vwdiesel] injector to head leak

[Chuck Carnohan]

 I did a bit of searching and I think that I'm using silicone vacuum
hose. I don't know how long it will last but so far- so good with about
3 months of service with dinodiesel not bio.... I think that I found out
about it on the vwdieselparts forum. I've tried regular fuel line and
vinyl tubing- vinyl but it was so floppy when hot and the last time I
got some, it leaked. I like to use this thin wall stuff as regular
rubber fuel lines won't go past the injector body on the nipple easily.
The fabric coated stuff is good (OEM style) of course but I don't have a
ready source for it where I live without paying through the nose! I have
also read you can buy some really good fuel return line material at
motorcycle shops (expensive but OK w/biodiesel).... I might have to
check that out next if this vacuum line fails. Others swear by it.

I've seen that.  But not on the return lines for the injectors.
