My Viair Dual 444C install

My Viair Dual 444C install
After asking around (here and other sites) I finally decided to go ahead and mount my dual compressors from Viair with 5 gallon tank.
After reading others opinions, I wanted the tanks to be mounted upright to get the longest life out of them. Not having a pickup, it made this a little harder.
I also wanted to be able to access them easily for any maintenance required.
Here's what I did.
First, I removed one of the "L" brackets from the factory running boards to make room. I chose to remove the "L" bracket under the B Pillar on the drivers side
The only thing I had around to mount them on was an old street sign. I painted the one side (back side of sign) which will face the ground. I used a stainless piano hinge to mount the plate to the Ex. I predrilled the holes on the Ex where the piano hinge will mount. I uses all SS hardware to prevent future rust issues
I lined up the compressors on the plate and predrilled the holes.
Next, I mounted the Compressors so the air intake will face the front of the truck.
Once everything was buttoned up, this allows access to the compressors after removing the 3 3/8" bolts which hold the plate to the bottom of the frame. It only takes about 2 minutes to climb under the truck, remove the 3 bolts and let the plate drop down to a 90 degree angle.
All I have to do now is finish up the wire looms and run the air lines.
I ended up using 8 AWG wire which was probably way more than I needed. I have them wired to a rocker switch on my F-650 Dash mod so I can control when the compressors are turned on.
After everything was bolted up, I noticed the plate I used is not as rigid as I would like so I will order a piece of 3/16" SS plate to eliminate all flexing when going down the road.
Now I can install the air tank & run the air ines as soon as the rain quits. More tomorrow.

The install looks great!
Do you have a plan for clean air? Using the supplied filter, drawing outside air, I lost my first compressor in <2 years. The pump cylinder was toast, and a rebuild kit wasn't much less than a whole new unit. Your vertical mounting will help improve service life. I remember seeing more aggressive scoring on the downhill side of the jug(mine was mounted at about 60°).

Thats a good idea. I have one of the hard mud flaps in my garage. I don't want the plastic fixed to my mounting plate because then it would not be able to hinge. I'll have to look a little more into that in a couple weeks when I get back in town.

After work tonight I mounted the tank. I mounted it between the drivers frame rail and the drive shaft, parallel with the frame. I used a tap to thread the brackets used so I wouldn't have to worry about getting the nylock nuts in tight spaces.
Next I installed the tank plugs, air hose connectors, psi switch and drain. I then ran the hoses to their destinations and completed the wiring.
After this was done, I mounted the front quick connector (for air hoses) on the drivers side front bumper support bracket, right next to where I had previously mounted my "Marinco Mod."
Then I installed the rear quick connect. I decided to mount it on one of the rear bumper support, It is next to where I mounted my air bag schrader valves
All in all I am very happy with the install. Everything works great. Hopefully tomorrow I can get all the wires tidied up and looms installed.
I also hope to to get the airbags linked into this system and then sit back and wait for my Shocker Train Horns to get here to finish the system.
