    You have a coupl of options. you can place a tee piece in the pipe vacuum pipe running to the fuel pressure regulator, or the pipe the vacuum pipe that runs to the diverter valve.

    I've used the latter, I placed a tee between one of the pipes under the inlet manifold plenum chamber and the hard metal pipe on the side of the head that ends up at the diverter.
