This is a borrowed photo (I'm not currently at home to take one) of the crank case breather from the Kirby. The tube shown in the photo was VERY brittle and broke when I touched it. I took off the crank case breather plate and as luck has it the gaskets broke. The second photo is of the home made gasket cut using my Silhouette Portrait Cutter (computer aided cutter), which is a cheap hobby cutter that I usually use to make vinyl stickers and heat transfers for t-shirts. I scanned the original broken gasket and then cut it using the Portrait Cutter. I think it came up well. There is a metal fitting with a barb on it inside the crank case breather. The tube fits into the barb. If I fit the tube to the barb and then try and push the barb though the hole in the breather plate it is very tight and breaks the tube. How is the plate, the metal barb fitting and the tube meant to interface?
