I'm not sure what hoses you guys are always working with but most of the ones I have had have a screw on fitting on the hose ends, not a swaged on type fitting. I can't tell by your picture but it looks like the fitting that is on the pump end of the hose is just a regular screw on type. All you have to do is cut the hose off at the fitting and put the fitting in a vise and screw the nut back off of the female threaded fitting that screws into the pump. Take cutters or a box knife and cut off the hose that was left inside the fitting and slid on the barb. Cut your hose off to the length you want and slide the collar over the hose, slide the hose over the barb, and tighten the nut back up. Here is a picture of an end I have that came off of a pump/hose. I'm sure there are some hoses that have the machine crimped fittings, but if you have those and just need one like this, I can send you one, I have several off of pumps I've built. I always save them for just such an occasion.....GB
