Veronica S.: Great set up. The tubing is a pain, you have to heat it up to get around certain areas as it is super tight and wound up in circles. You have to be very careful when tightening the brass fittings. Use blue sealer so you can take out any fittings in case of breakage. I did need to out the compressor far from the tank so I needed an extra hose to connect each.

Nick L.Nick L.: Wow this air compressor works well! I installed in my enclosed trailer in what I think a pretty good spot! Was simple and came with everything I would have needed. A few of the bungs didn’t seem like they were threaded correctly but that could have just been the lock tight already on all the connections. Some of the wire leads could have been a little longer coming out of the pressure switch but I made it happen. If you watch the price it might drop a little... overall I’m super happy with the purchase maybe if they included some wire loom

Chad: Working great so far and was able to get a nice, clean install on my 2011 Tundra. Put the compressor up under the hood on the passenger side and the air tank under the truck just in front of the gas tank on the driver side. Put a quick disconnect in the rear wheel wells​ on both sides of the truck. The kit came with enough air line to run everything. I did have to pick up some extra parts (on Amazon), including: two quick disconnects, two tees, and a plug for one of the tank ports. Took me a while to install but I was being meticulous. I did call Viair support about remote mounting the relay and they were very helpful. Ended up sticking the relay under the hood, teeing off the line that I ran from the tank back up to the pressure gauge, which I put in the glove box. I didn't use the gauge/switch mounting plate that came with the kit. I mounted the switch in one of the empty switch spots to the right of the steering column. The switch also powers the gauge backlight. I have the switch turning on a separate standard SPST relay next to the battery that then powers the pressure relay that came with the kit. So, if the switch is off, I know for certain everything is...

TJ: Installed 200 OAS in a 2008 Ford F250 Super Duty diesel. In addition. I purchased the Viair bracket for the compressor. The product does exactly as promised. It takes about 5 minutes to fill the tank from 0 psi.
Viair could improve their product by providing self locking nuts for the compressor and tank. Provide a Viair bag for the accessories to store in the vehicle. Make a bracket similar to the compressor for the air tank. I had to install the air tank on it side so it would mount to the frame rial of the truck. This means the drain value sits half way up the tank until I can get a bracket custom made so the DV sits at the bottom of the tank. Viair should provide all the male and female electrical connectors to do the job. I had to buy several electrical connectors to make it work according to the instructions.
I added Viair's pressure regulator value and two more quick connects since the kit only comes with one quick connect. I did have to purchase 1/2 hex bolts to mount the air tank to the frame rail of my truck since the bolt, washers and nut seemed a bit weak for off roading. Over all I am please with the product and the help provided to me...
