When I cleaned mine, a snapped the green one. Go get some vacuum hose from the parts store... 3/16, i think. I dunno, but take a small peice of the busted tube with you, get a vac hose (the flexible ruber stuff) and find one with an inside diameter that will fit over the existing brittle pipe tightly. Put it on, zip tie it. Works fine.

SHouldn't need more than a foot.. abnout 3 bucks. I called ford on that hose and to get replacements, it was like 45.00 a peice.
