A few years ago I was at a sportsmen’s expo in Portland, Or and a man was tucked away at one of those back corners reserved for emerging entrepreneurs. There was a man selling K-Pumps. I do believe it was the first time I had seen the name or the product. I bought one and have never regretted the purchase. It is small (there are several sizes now) and does a great job inflating pontoon boats and rafts. The two handed barrel pumps are good too. But, I have come to rely on the K-Pump most of the time. The prices are still reasonable and it is a simple but powerful tool.
