Well I actually got them on, I had struggled for about an hour before posting but then got both on with in 10 minutes. For me it was all about getting my hands in te right place, needle nose pliers to start it in the nipple, nipple, nipple. heated them, placed an awl in both ends while heating and moved the awl in further as they heated. Have to have the pliers just about 1/8” from the end of the hose while starting it otherwise the hose will just buckle, and start the hose on a 45 degree angle to the nipple.😀
