The hose assembly was a deal at $10 + tax. Easy to remove the old; install the news one. I saw a complaint that the news hose does not come with a plastic clip to store the hose. That is true - but the Specialized Pro pump has a hose clip on the pump - thus not really needed.
The part was shipped to my local bike store. They had received the part; put it aside as they were " slammed" with work; then forgot to contact me.
That is why I gave the 4 rating.
Also, if possible, be sure to troubleshoot that your problem is the hose or hose head. It ends up my old Specialized Pro pump has some internal problem somewhat restricting inflating my presta tubes easily and thus the pump head slightly disengages from the presta valve. Oh well .....
