2nd Gen Non-Engine/Transmission AC condensate Drain

Does anyone by chance know the size of the AC condensate Drain on 99 2500? The drain isn't clogged but it's draining into the cab very bad.

I used an old spark plug elbow on mine. The nipple outer diameter is 9/16 on mine, yours is probably the same.

The foam seal allows water to run back down the tube and leaks into the cab. I clamped a piece of 5/8" heater hose on mine. The clamp is probably not needed, just assurance it won't call off.

Yes sir I figured the seal was the problem, I just wasn't sure of the size of heater hose best to use for the drain. Thank ya.
