Trimming the duct and and using the right angle version made it where the duct does not have to be removed. attach the hose, reach on the other side and flip the lever. done.

 

What is the ID size for the hose everyone is using?

If the ID size isn't handy, where has everyone purchased the hose they're using?

 

I bought at Home Depot - in the plumping section they have a selection of plastic and rubber hoses. I just carried the valve in, before installation, and played until I found what fit and then bought a foot. My local ACE also has a selection and I'm so does Lowes. You are just using this for a gravity feed - no pressure - so no worries about strength or 'auto specific' stuff. None of the standard auto brake/fuel/heater stuff I had around was exactly the right size altho the plastic air line I needed to pipe the air horns was close

 

Capt...

Did you end up buying rubber or plastic tubing?

As you know, I already have it installed, so doing a test fit isn't an option unless I purchase 2" or 3" lengths.

I have a BUNCH of leftover, brand-new silicone tubing that is used for supplying air to fishtank decorations...I guess I'll see if that will work.

At least I'll know if I need to get bigger/smaller tubing...

Nice horn setup, btw.

 

either will work

the chunk I use is clear plastic
