[Vwdiesel] injector to head leak

[mikitka]

It is the urethane fuel line that they run on the motocross bikes, I got the
blue stuff and it has been on my main fuel line from the filter to the IP
and then from the IP back to the filter for over two years and it is just
like the day I put it on.  Great stuff. I paid 90 cents a foot for it at the
local motorcycle shop. They do not have anything, at least mine shop didn't
have anything small enough to go on the injectors. There I used tractor
trailer air brake line which has been on for over three years now and about
40k miles.

 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.
