I got tired of cleaning my blow-off tube. Soaking 4 feet of 1.25" OD tubing is a PITA, and trying to get a brush through it is even worse. I finally gave up when I was pulling my brush through the hose and the string broke, stranding my brush inside.
I chopped up the hose, got some 1" PVC pipe and some elbows. That works much better. If you push the pieces together, they hold fine without cement, so that you can take it all apart again.
Here is a really bad picture (SWMBO has our camera). But I think you can get the idea.
