    Problem with boost gauge

    I have a zafira gsi, 53 plate and I have fit a boost gauge but it doesn't seem to be working very well. At best it is showing about 4psi of boost but also there is no vacuum. Have I got it piped up in the right place? At the moment, its coming off the actuator. Should it be piped elsewhwere?

    Fuel pressure regulator. You can find it under the cross over pipe, the black steel pipe over the engine. It is also in conection to the Throtlle body.

    off topic, but where is your oil breather hose going. i need to do something like this as my one (running from elbow on inlet pipe) keeps splitting

    to anwser adetel's question, just to the left of the tophat, you can see a small white tee peice, this is where a boost gauge comes from, i ran it from there through the bulkhead above the pedels.
