Capricorn PTFE is well regarded as the highest quality PTFE tubing in all of 3D printing. The tight tolerances make sure that the filament is lead directly to the hotend with as little room for error as possible between the extruder and the hotend.Capricorn PTFE XS Series is rated for withstanding the highest temperatures in the market which is perfect for printing exotic filaments such as ABS, Nylon, and Polycarbonate. Standard PTFE tubing may experience dangerous “off-gassing” if the hotend is heated to temperatures beyond 240*C and will get worse with higher heats. This Capricorn XS series is safe in 3D printer usage up to 300*C thanks to its proprietary manufacturing methods.Upgraded Pneumatic Fittings with metal teeth provided in this package work much better than the stock options provided by many cheap 3D printer manufacturers with plastic teeth or cheap locking mechanisms. The extruder fittings are PC4-M6 and the hotend fittings are PC4-M10. A clip is also provided which drastically increases any hotends precision by eliminating any potential slippage of the Bowden tubing whilst extruding or retracting.One PTFE cutter with an extra sharp razor is also included to ensure that the PTFE is cut flat on both sides to prevent any malfunctions or heat creep when feeding and retracting.1 Meter in length PTFE tubing

Yeah, that tube is toast. Try pulling the tube down through the coupler, as there is a huge bulge at the bottom... Though you've probably already tried that.
I would recommend all new couplers while you're at it. If you're on the stock couplers, they are pretty much crap.
If you don't have a length of tubing to replace it, I would recommend this kit:

It's a full meter of tubing, two complete sets of couplers, a tube cutter and clips.
If you don't need the tubing, the couplers can be had for a few bucks.
I have had mine for 3 months and I only replace things when they break. I now have replaced my Bowden tube and couplers with a capercorn tube and metal couplers. https://www.amazon.com/dp/B07PS3NH82/ref=cm_sw_r_sms_apa_i_GltDDb67XDCT1
Then my extruder broke had to replace it. https://www.amazon.com/dp/B07QHBNYD9/ref=cm_sw_r_sms_apa_i_KmtDDb9WPKV3T
Also a glass bed just cuz also get a bunch of .4 tips cuz you don't want to mess with cleaning or a degraded hole when you are already replacing stuff. But that was all in the little time I have had it. I maybe have done 50 prints. Although some had tons of parts.
No fan shrowd or fan replacements yet....... I am running basic cuz I am new to this but I learned a ton in the short time doing this.
It's most likely your PTFE tubing. I recommend you get this here: https://www.amazon.com/Authentic-Capricorn-Filament-Upgraded-Pneumatic/dp/B07PS3NH82
I just installed it and my prints are beautiful.
