This pump was only used to inflate tires on my class c van. If it worked, then it was fine. It easily connects to the Mercedes Sprinter engine for increased power. Suddenly he began to roar, and the air would not be released. I paid for shipping from Florida to Viair in California. The service department informed me that the cane came loose and scratched the cylinder. The repair costs $119. In my opinion, this is a manufacturing defect (made in China). I am very dissatisfied with this customer service and the way it was handled. Revain has decent pumps for the repair cost. I expressly do not recommend this product. I'll let Viard keep the pump.
