[Vwdiesel] injector to head leak

[Chuck Carnohan]

 Nick, That's right- air line is what I'm using and it is tough! I've
been able to shove it on the barbs with pliers- no heat. Thanks for
clearing this up!

That's air line, pressure, not vacuum.
Tougher than a pig's nose, resists everything, but not too great at
bends and things.
If you go to a supply house Sandy, ask for the stuff used on the
geearshift- on the transmission airswitches (high low range, etc)  Main
air line is 3/8 and 1/4"or so.
It's pretty stiff, you'll have to heat the ends to get it on the hose
barbs -james
