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.
