Yah, I almost resorted to that but I figured out a another method. Second Pump tube took only 2 minutes to get on
(use your fist like an "anti-kink" sleeve around the tube. Put it at 45 degree agle to barb, push and push and push. then Pull the tube towards the "high side" maybe pull the tubing back off a little to get it even and push some more

)
The "sleeve" works to keep the tubing from just crushing up against the barb and not going on
