Does anybody know if I can use a substitute for the drain hose #13?

Yes, you can find similar tubing at your big home omprovement stores.
Also, try using the search function here - lots of related info available.

What is the diameter equivalent in inches?

For a long time, Osh or Orchard Supply had it. They called it irrigation hose. It was $25 for 20 feet. Exact same size.

Last week, i saw some at Home Depot in the garden section. Maufacturer is Beckett.
Here's a pic:

I bought mine here: http://www.greenlinehose.com/

"G930… CORRUGATED BILGE HOSE"

$0.60/ft and has a nice "clamping cuff" to fit over the funnels. It is a bit wider diameter but is a decent solution.

Check your local Yellow Pages for hose suppliers.

Mine is a 4ft piece of washing machine drain hose from Home depot. Same diameter, and the end is smooth without ridges for about 4", letting the tube poke through the rubber grommet in the tin real smooth. Hacksaw cut to length

I used the irrigation hose, and had to make a little inner-tube joiner splice out of vacuum hose to attach irrigation hose to the funnels... had to skip the spring clamp.

Anybody know if the spring clamps (part #12) are available anywhere?

Isn't the fresh airbox drain hose the same?? There must be a ton around with all the cars that have been dismantled.

30+ year old brittle plastic. Go with fresh new material.
