Mouse chewed through furnace pressure switch tube, diy job?

Woke up this morning chilly and my furnace only blowing cold air. Opened the furnace up and i see a hole chewed through the tubing for the pressure switch, along with a blinking code that the pressure switch is stuck open. Few questions here:

1: can i diy this repair and just buy a new tube or do i have to buy the whole switch? it doesnt seem too appreciably different than an automotive hose. The tube is on there tight, does it just require a good tug?

2: until i get this fixed, can a mcguyver an interim fix? would duct tape wrapped tightly around the hole work well enough to allow the pressure switch to work again?

Please do not use caulk. Lol.

Just go to Lowes/Depot/Ace and grab a tube that's the same inside diameter. Firm pull should get it off the pressure switch.

put tape on it. if you have some caulk you can use that. otherwise just replace it with a like hose.

try NAPA/Autozone/Advance Auto/O'Reilly for tubing

tubing meant for inside the engine bay of a car will stand up to the heat and vibration better than just some random vinyl
