A final decision on my Big Red compressor location

Image Could Not Be FoundImage Could Not Be FoundI posted a few weeks ago for help to find a good spot for my compressor in my GU. As i had a dual Battery, Heat exchange and bypass oil filter, i had no room in the engine bay, the only spot available was really too low a was on the radiator support panels. Even in a super low water crossing it would still get soaked. The Big Red is supposed to be sealed but i still would not risk it. Many suggestions were put to me for an inside vehicle mount which would me preferable to me but due to my very standard vehicle, those places were not available. I suggested to all that it may be possible to mount it inside the spare wheel carrier, at least it would be fairly high on the vehicle and the outlet very accessible on the outside of the vehicle.
Well, I decided to go for mounting it in the spare and have expanded my project to include the spare to be used as a tank with about 100 litre capacity. Thats about 10 times the normal tank that most guys install but it will be only 65PSI instead of about 100PSI The maximum pressure in the sidewall indicates 65psi so i set about to include the spare to that pressure. If the spare is damaged and not inflatable, i have included a small ball valve to stop air going to the spare tyre.
I made a blow of valve to start to work at 70 PSI and it shuts of completely at 65 PSI. Toggle switch and 30amp relay inside the vehicle, I will include an electrical contact, pressure switch at a later date so the compressor cuts out completely and this will give me a secondary safety aspect. So attached are a few pics to show what i have done, it has to be painted and installed this weekend hopefully.. MichaelImage Could Not Be Found
