Where this on-board air kit fits your vehicle
This VIAIR kit mounts inside or outside your vehicle, whether that means the bed of a truck or under the chassis. That flexibility is the first thing to weigh if you run air horns or a load-leveling setup and want the tank tucked out of the way.
The 2.0 gallon tank carries five ports and the compressor is the 280C model, so you have room to plumb horns, a suspension line or light tools. We recommend confirming that your vehicle has the space and wiring route for a tank-mounted setup before you buy.

What this compressor can and can't diagnose
The kit supplies compressed air for air horns, air suspension and many pneumatic tools, and it can top off tires plus inflate bike tires, beach toys and camping mattresses. The tank refills to 145 PSI in about 3 minutes and 40 seconds, so recovery between uses is reasonably quick.
It is not a fault-finding tool and will not explain why a horn or suspension system is misbehaving. A lower price does not prove any component is working, so treat this as an air supply rather than a diagnosis.
30% duty cycle at 100 PSI runs 30 minutes continuously, with a flow rate of 1.59 CFM.
Best suited to topping off tires and powering horns or tools, rather than filling a flat truck tire from empty.

Power and mounting checks before you buy
Confirm how you will mount the 2.0 gallon tank and 280C compressor, because the kit supports inside or outside placement and the location affects how you route the leader hose and reach the drain cock. The tank includes a pressure switch, safety valve and drain cock, so leave room to access the drain when you plan the spot.
Check that your wiring and available space suit a tank-mounted compressor rather than a handheld unit. The kit is IP54 rated for dust and water, so an exterior location is possible, but still verify that your chosen spot keeps the fittings protected.
Decide whether the compressor will serve horns, suspension or light tool use, since that determines the fittings and connections you need. The five tank ports give you options, but you supply the rest of the air line.
Who should choose this VIAIR air source kit
Choose the 20005 kit if you want a tank-mounted air source for horns, load-leveling or occasional tire top-offs, and you are ready to plan the mounting and wiring. Skip it if your main need is a portable compressor for fully flat truck tires or a tool that reads vehicle faults.
Before buying, confirm the mounting location can accommodate the 2.0 gallon tank and that you are comfortable sourcing the remaining air line components for your setup.
