Putting a boost gauge on the A pillar and want to run a tube from the boost sensor to along the scuttle , in through a wee hole somewhere around the brake ,master cylinder/windscreen wiper area and out through to the A pillar...anyone any ideas where to start looking? Any handy little grommets begging to be used??L200 K74 Ta Nik

when I fitted a boost gauge I used an oval shaped grommet on the bulkhead behind the battery that appears underneath the back of the glovebox

Got it...cheers..Nik
