I am trying to get the speed control on my 1992 XJS working. During my
checking things over I have found that on the vacuum pump there is two
larger ports one has a line with a ''T'' in it with one side to the
dump valve and the other to the actuator. There is a second port
on the vacuum pump with nothing on it. What is this second port
tie into? The picture in the Jaguar Classics parts list shows
nothing attached to this port is that correct?
Thanks for your help.
