If you take out the rubber grommet, the whole is just a hair larger than a 3/8" ID hose. I'm not sure exactly how to wedge it in there for a tighter fit but I'll cross that bridge when it's forced upon me.
I am thinking that if you drilled our a larger hole, you could do it so that a 1" hose would fit very snuggly, and be a good blow off tube. I'd like to see pics if anyone has them too!
