Boost gauge hose through the bulkhead with no heater cable next to clutch

On my zs td i fed my boost hose through the heater cable grommit next to the clutch pedal. I now have a 45 td and i dont have this grommit. I think thats due to the 45 having air con.



After looking around on the internet a lot of people seem to get lost when fitting boost gauges. Like the isue i had, they cant find a way through the bulkhead due to no heater grommit so here's my 2p's worth-



Unscrew the 2 bolts holding the expansion tank in place. Move this to one side and put a hole through the large black rubber grommit.

Put a slim solid object through the boost hose as can be seen below.

I used a phillips drill bit-







Then feed the drill bit through the grommit and it will pop out just behind and above the fuse box like so-







Job done :-) Bolt the expansion tank in and fit the gauge.

This is how mine now looks-











Cheers, Dave
