On my new P38 I am using a ARB compressor as one aspect of "bomb-proofing" my EAS. I plan to use one of their larger compressor and it wont fit where the old one is. Not to mention it will be easier to run a external air tap from the trunk to inflate tires. My question is from the spare wheel well, what is the best way to get to the front. Somehow outside of the car along the frame rail and too the valve block? Or can it be ran through the trim like sub wires and go through the firewall. Where is a good hole in the firewall? Having it outside of the car does worry me slightly that it could get damaged offroad.
