[Vwdiesel] Yellow Dot Pumps & Associated Stuff

[mark shepherd]

Thanks for that. I used to have a copy;  think I sourced it from Roger's 
Caddy site many yaears ago, but I have a feeling it's stashed away on my old 
computer, that I'm meant to be throwing away. The chart in Fig. 43 is most 
useful as it shows the performance/function variation of 20+ pumps.
