Review on 🚙 Efficient 4 Tire Inflation System for Jeep Wrangler JK & JKU - Engine Bay Mount, Driver Side Rear by Donnie King

UPDATE: After some real hands-on use of this system and trying to 'fix' it and try other or simpler methods, I came to the conclusion that this is the system is useless. The valves don't let enough air through, the tubing is too small and the valves seem to be loosely connected to both the tire and the valves installed in the system. You are better off building just one T with two long lines and working on two buses at the same time. I bought a 1-3 adapter and added 2 long lines, added a pressure gauge and it works better. Great idea, poor execution on Betty's valves. The bridges that hold the system together use handy Betty valves for quick attachment and detachment of valve stems. The problem is that the internal design of these valves severely restricts airflow, which is the main purpose and function of the system. It takes TOO LONG to actually raise or lower the air because of these poor flow valves. Worse, they don't flow at the same rate. Some are slower than others and take up to 20 minutes (after you think it's done) to actually stabilize and balance all 4 tires. I replaced those poorly designed valves with a different type for better airflow. Now it works! But the customer does not have to redesign and rebuild what a properly designed system should be. In this case I could just build my own cheaper from scratch and it would work more efficiently from the start. I'm only giving it 2 stars because of this basic flaw in product quality review. I don't think the manufacturer actually uses and tests their final retail product on their vehicles to ensure its practical purpose is working as it should.
