Hi Turtley:
Hey, from what you just posted I am thinking you should
remove the cap that is capping the spray attachment and then
take that AND the
universal hose set-up and make it so it all matches up
IN STORE...then take it home and finish this sweet and easy!!
It means two trips...but it also means a completed job without much hassle guessing which fittings work at your cabin (just to find you don't even have the right reducer...

)
Let me know what you think...
