[Vwdiesel] injector to head leak

[James Hansen]

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
