no it cant go there, it needs to be on the other side of the butterfly, i.e on the crossover pipe between the turbo, and the intake, you have to weld a pipe on it and drill a hole through to the main pipe, i think BOV's need a 1" OD pipe to connect to.
the vacum end on mine is 'T'ed into the little pipe for the fuel pressure reg.
the boost gauge can be piped anywhere after the butterfly, so i guess the same pipe for the fuel pressure reg will do, the std S12 gauge is piped off from the servo unit supply, you will see adaptor clamped to the bulkhead next to it, then the little pipe runs along the bulkhead to a box under the windscreen wiper motor down by the turbo.
hope this helps
