I drilled mine it was alot easier to do it, took me no more than 30 mins, then fed it up through the fuse box and up through the pillar.

yeah that would be great yeah i've heard you can run the pipe through the bonnet cable gromet could i do this an where does the boost pipe connect to? have u got a picture of that aswell matey thanks:D
 
you don't need to drill your manifold! the vacuum pipe from the boost gauge goes to and is t pieced at either the diverter valve or the fuel pressure regulator as for wiring i'm still not sure on that but have a good read and you should get the general idea, i'm in the process of attempting to fit a boost gauge too!
