[Vwdiesel] Latest fun :-)

I found that the plastic air brake lines that you can get at a truck repair
shop work really well. Can't remember the size but if you take one of your
old ones they can match it up. It holds up to diesel really well and it
isn't very expensive.

Hello All, Just a question about fuel return lines, the ones between the 
injectors, i need nw ones
and remembered someone suggesting Mcmastercarr. they have a fuel and 
lubricant tubing called
tygone in 3/32.1/8, and 3/16 id. I assumed this was the type for our vw's 
and would experiment
with the size as it is cheap.
thanks, ray
