They stock a

lot of the Earl's stuff and are willing to order anything else from the
catalog.  Earl's has AN-24 and larger stuff, thermostat housings with AN
fittings up to AN-24, weld on brass and aluminum radiator bungs up to AN-24.
The AN-24 hose is 1-3/8" ID and 1-45/64" OD.  AN-28 hose has a 1-1/2" ID.

The dash number is the number of 1/16th of an inch. Dash 20 is therefor

sixteen 1/16th's or

one inch plus four 1/16th's or 1/4 inch so dash 20 is 1-1/4 ID hose.
Dash 24 is therefor  1-1/2 inch ID hose. Page 102 "Airframe & Powerplant

I think Summit 1-800 230-3030 sells AN type fittings and SS hose at a

discount compared

to what they charge in a retail outlet. Note it is not real AN. It is made

to appear to be real AN.

I knew Earl when he was selling surplus stuff out
of a store front in Lawndale CA 30 years ago. He sold out and now it is a

huge

corporation with a large building to match. They are now set up to
be a manufacturer with a strict hierarchical distribution system.
No way will you get them to sell at a discount.

Paul,
Sorry for the apparent mis-information but I was just copying straight out of the Earl's catalog.
