[Vwdiesel] Yellow dot pumps and associated stuff.

[mark shepherd]

The yellow dot pumps were a different breed to the usual ones, and as far as I can tell had a steeper rate of pump pressure, possibly implying a faster dynamic advance. 
They were timed to 1.15mm aparently, but a recent rumour is that the injectors were set to 180 bar, rather than the more common 130 bar!
 Does anyone know if that is correct? 
Apparently an early Bentley will have the info.
Cheers,
Mark
