Some places (maybe harbor freight or NAPA) carry a special pair of pliers especially for crimping hoses, they kind of look like a cross between vice grips & small needle nose pliers, they have flat pads instead of teeth that just gently pinch the hose shut, but no sharp edges to puncture the hose. I bought a pair & thought i'd only use them once, but I use them a lot more often than I thought.
Good tip, I'll put that on my radar....:thumbsup:
