W/washer "Y" fitting works fine for right side of carb, but hose on the other side is bigger fuel line. I picked up a package of "T" fittings @ CTC (crappy tire) and used one that fit. However would be much easier wit the correct size "Y" fitting. I would cut a 1/4" off the bottom of the hose and bring it in to NAPA for them to match up. Good luck!
