[Vwdiesel] Early Fuel Pump

[David Cook]

Look at the VW part number.  If the last letter is
"A", then it is a yellow dot.  If the last letters are
"A*"  (* being any second letter) then it isn't a
yellow dot pump.

Yellow dot pumps are set at 1.15mm, the setting for
other pumps is a topic of debate, but the most people
say it is 1.00mm IIRC.
