Would recommend either 3/8" or 1/2". Keep in mind the EDC should be putting out approximately 9 cfm. I don't think a 1/4" opening is gonna flow that much air without restricting is some. Was trying to think how much cfm a large air powered buffer would use (like what an auto paint shop would have). Those might be more like 5-6 cfm. Anyway, if you have to stretch the rubber hose over the fitting A LITTLE, that would not be bad. But you probably would not want to stretch a 20 year old A/C hose much because it will probably crack.
Looking forward to some pics from you and Mazda23 of your setups (hint hint LOL)
