Sunroof drain tube - dimensions?

I try to take my truck through the car wash every week in the winter, since the municipality likes to layer cake the roads with salt in the winter.

Alas, my sun-roof like many others leaks. It has been cleaned a few times, and I just want to replace the tube.

I just happen to buy some tubing yesterday to do the diesel fuel water separator purge, but the ID was way too large, learned a lesson about believing what was written on the labels!

That said, looking at the tubing I have, and looking at videos of people modifying their drain tube output, it looks similar in size.

But I don't want to go pulling off panels, especially the headliner, if it won't fit. So I am wondering if anyone has measured it before?

Went out to figure it out, since I'm impatient. Did the drain nozzle mod while I was in there. Hopefully that fixes the issue.

Outer diameter is ~10mm, so a 25/64 or 13/32 should work.

Inner diameter was ~7.5mm, so 19/64 or maybe 9/32 will work.

I figure that since at the top of the tube, it fits around the outside of the input nozzle, having it slightly smaller is better, and as such, 9/32 is slightly smaller.

At the bottom of the tube it fits inside the output nozzle, so slightly larger is better, and as such, 13/32 is slightly larger.

I used the following chart for conversions > http://mdmetric.com/tech/cvtcht.htm

As for the nozzle mod, relatively easy to do, easier to do in the summer when **** isn't cold as well, and wirelooms are difficult to bend! I haven't tested it yet though, going to the touchless car wash in a few minutes, will report back!

Back to report there were no leaks, so it is fixed for now I hope. This summer, or maybe even spring, I intend on replacing the corrugated tube with some silicone tubing, or maybe some of that clear braided tubing.
