Very easy to install as I did it myself. VERY fast fill times if you empty the tank completely or just honk a little. Best of all, the pump isn't too loud, as I found in the cab of my '91 Ford Bronco. The seller was very knowledgeable about the product. and there is excellent customer service. I've had and burned out 3 other brand pumps and had issues with poor customer service and this is the WAY. Save yourself the headache (unlike me) and get the best of the best, right the first time. Don't go with similar or different brands. To update. replace 2. The rubber seal on 1 compressor piston head has failed causing 2 to operate continuously at only 85psi. buy again. lasted 6 years. Too bad I didn't sell the 2nd pump. live and learn
