PTFE TUBE REPLACEMENT
whenever i have difficulty loading a filament on a toolhead, i usually would remove the PTFE tubing connected to TH and push it in. In my recent case i was working on TH5 and as i had difficulty loading an ASA filament, i tried to take out the PTFE tubing as i usually do and had great difficulty. Usually, pressing the "blue" part on the bowden tube would do the trick but not in this case. I ultimately was able to pull the PTFE tube out and guided the filament to load.
I am now thinking i may need to replace the PTFE tubes on my XL. what have you guys used as a replacement. I really like the Capricorn one's BUT seems like they only come in solid blue color so that'll be an issue, since i wouldn't be able to see a filament go through.
TIA for your kind inputs.

I've used these:

I replaced the PTFE tubes with Capricorn. I don't mind the blue color. Not sure it was necessary, but it couldn't hurt.
RE: PTFE TUBE REPLACEMENT
I replaced all my tubes when I bought it with 3mm id tubes, and bypassed the side sensor. I feed directly from my drybox.
The 3mm id tubes have much less resistance than the OE tubes. I also run an enclosure. Over 1800 hours of printing now and they are still in good shape.

Exactly what I have done as well (bypassed side sensors, replaced PTFE tubes with larger I.D. tubes, running a (heated) enclosure). I'm also somewhere over 1,700 hours of printing with this setup and it is working quite well (boy do I *not* miss the side sensors).
RE: PTFE TUBE REPLACEMENT
I seem to be getting stuck filament problems suddenly on the XL 5T, and I think the issue is the Captube that I used for the inlet tube on the spool side of the side filament sensors. I just figured out that they sell 2mm ID (which we bought) and 3mm ID. Pretty sure we bought the wrong thing (or maybe the Filament Guide tube wasn't available when we purchased; not sure). I did a side-by-side comparison of pulling filament through the factory tube and the Capricorn tube and there was a noticeable difference. Especially for those short inlet sections, it's probably worth the $10 chamfer tool that Captubes sells.
