case - nanuk 910. I needed as low profile a case as I can get because I wanted to be able to store in a rooftop cargo box. that case is the minimum size you can use to fit everything, you can obviously go bigger. green hose, plus battery cables all fit no issues or cramming. you can tuck the battery cables in at the top and it all fits. you need to be strategic with the layout though, I have room to change the filter, access the power switch and made sure there's enough room at the top of the compressor housing for air escape. I mounted the manifold as close to the front edge as possible. bigger cases will allow more flexibility
the compressor is viair 400p-auto. I took the sand tray off the bottom and repositioned the metal feet, note you have to reverse the 8 hex head cap screws. the capped nuts go on the inside but I had to move them to the outside to fit the m8 mounting hardware (my viair has exactly m8 sized holes on the feet). I also took off the quick connect plug and replaced with a 90 degree elbow and brass quick connect plug so the connection is easier to get to. note do not put a female quick connect on, this is a safety issue, keep the plug
mounting hardware compressor: 4 m8 35mm bolts (I think they are 35, but 30 will also work), 4 nuts, 4 washers for the compressor. there is 1/4" rubber isolator strip under each compressor mount. EPDM washers under the bolt heads on the bottom of the case for weatherproofing
mounting hardware for the manifold: 1/8" thick aluminum flat, it's about 12" long, two m6 30mm hex cap bolts with EPDM washers under heads. two m6 washers and 13mm of nylon spacer, m6 serrated bolts to secure the aluminum flat
manifold: viair manifold. I used a winter's 2" PSI gauge (just fits) and you can see the various couplings I used along with the flexzilla hose. there are 1/8" rubber feet on the bottom of the case because the bolts heads are just a tad too tall on the bottom of the case. there are two valves which will allow you to shut off the air into tires or whatever you are inflating to get an accurate PSI as well as to also allow air out or have a male plug for other accessories
if you are interested I can PM you the links to the exact products I used (they were off amazon.ca) and send some detailed pics to show mounting. or if anyone else wants to know I can post here or make a new thread
