Hello people.
I have a 1974 S3 XK-E and I'm unsure where the vacuum lines from the Stromberg CD175 body go to.
There is one very small brass vacuum port on each of the carb bodies on the top right on the throttle plate side. It appears that the two front carbs are linked by a vacuum pipe from one bank to the other, but the two back carbs are not connected to anything causing a possible vacuum leak.
Can anyone tell me where each of these vacuum ports connect too, or is it the same as the two front carbs and they are connected together from bank one to bank two.
Regards
Mazzerman

 

While the vacuum and emissions plumbing of the '74 is slightly different than on the '73 I think this thread should answer your question:
