[C320-list] hose barbs

[wflowe3 at aim.com]

I have a dedicated water tank plumbed to the head.  It uses white 3/4" vinyl tubing to make the run from tank to head. I want to plumb in a shutoff valve so that I don't have to drain the tank if I want to work on the toilet pump assembly.  I've cut the hose, purchased the valve with 3/4" plastic hose barbs and I cannot get the barbs to fit into the cut hose.  I've tried lubricating them with liquid dish soap-no luck.  Tried heating the hose with hot water--no luck.  Any suggestions?
