Rusty,
The evap cores come with tubing already attached.
I used the existing 3/4" as the inlet and welded an aluminum ring near the end to act as a barb when using 3/4" heater hose. The 5/8" outlet was removed and the hole reamed open to allow a 3/4" elbow to be welded in with a ring barb on the end. This "elbow" was a piece of tubing that was recovered from the inside of the reservoir tank that was attached to the used evap cores. After removing the tubing from inside the reservoir tank it was welded back together and used as a coolant filler/header tank.
If you are looking for a simple (and cheap) solution
you could use this same method. My cores came from junkyard 1986 Buick La Sabre. They were $50 each which included removal and reservoir tanks.
They have the inlet on one side of the core and the outlet on the opposite side. This worked well for my application. See the attached photo as a reference.

Subject: [FlyRotary] aluminum hose bungs/fittings
Greetings,
I'm trying to decide on the fittings for my evap cores, and I haven't found
much to choose from. Straight AN bungs are pretty common, and I've also
seen some NPT female bungs. What I haven't found is any hose barb style
fittings. Ideally, I'd like to find some options for 45, or 90 degree hose
barb type fittings, in about a 3/4" size, since there isn't much clearance
under the outer tanks of the evap cores. Can anyone point me to a place
that sells these? BTW, I still haven't officially decided if I want to use AN hose, or just
good quality "heater hose". I'll certainly keep AN hose for oil, but I
think heater hose is probably fine for water, especially with all my
possible plumbing methods. Thanks,
Rusty (evap cores temporarily in place)
