Broke a plastic hose, any ideas for repair?

I used a small copper plumbing adapter the fit inside at Home Depot. Coated the fitting with JB Weld and slid both ends of breather hose over fitting. All sealed up!

Electrical tape will absolutely not work (from experience). The self vulcanizing tape actually sounds like a good idea.
I used special high-temperature heat shrink tubing. Repair still holding up several years later.

Best to replace it and if that one was brittle and broke, but the others too.
For a short term fix you can get the proper size heat shrink waterproof tubing with adhesive inside. Slide it over the break, use a heat gun to shrink it and activate the adhesive and it should hold and seal.
This, in the size you need
Thermafix Plus semi-Rigid, Dual...

It needs to be high temp heat shrink. The glue is really irrelevant.
I think this is what I used, but I'm not sure... I got it from a guy at my work for free.
It says you need a torch, but I used a 1200W heat gun. Maybe the stuff I had was thin-walled... or maybe something else.
But the regular black heat shrink tubing I used the first go-round lasted a few hours and then popped off while starting. Turned all soft.
Because of its resistance to high temperature, it's ideal for use as heat shrink tubing in extreme conditions, and also comes in an adhesive-lined Teflon PTFE version for extra protection.
The only drawback, naturally, is that because of its tolerance to high temperatures, it requires a lot of heat to make it shrink, which can only be achieved with a torch. Its shrink temp is 617°F to 644°F (325°C to 340°C).
Its continuous operating temperature ranges from -454°F to 500°F (-270°C to 260°C) and it's resistant to almost any chemicals, except alkali metals in a molten state, fluorine gas at high temperatures, and chlorine trifluoride.

Teflon PTFE (/12)
When most people hear Teflon®, they probably associate it with stuff sliding right out of their frying pans, but it's so much more than that. It's the brand name for Polytetrafluoroethylene (PTFE), which is a synthetic polymer containing fluorine and carbon atoms locked together in a chain.Because of its resistance to high temperature, it's ideal for use as heat shrink tubing in extreme conditions, and also comes in an adhesive-lined Teflon PTFE version for extra protection.

The adhesive inside makes a better seal and prevents leaks through the hose ripples, so no, not irrelevant.
The one I linked to is good to 266 F

I used some gorilla tape on mine for a quick fix until I got a new one from FCPEuro as listed above. Actually I think I found one cheaper, you can google the part number. When they're already that brittle they're just going to break somewhere else, hose or a fitting, just replace it now to stop any weird issues in the future. One less thing.
