You can get stainless braided hose for this. Had a mouse chew thru the hose on my Buddy propane heater. That thing works really good!, but need a new hose. I have about 20 or so feet of braided left over from another project. Fittings should not be a problem.

Last Monday I went up to the property. Walked by the generator and a hole was chewed thru the plastic gas tank. I am thinking WTF mad Chipmunks or Squirrels, both are quite prolific in the area, and not enough predators. I need to get a pet Bobcat or two laugh
It's a thermoplastic so I can weld a patch over.

Glad you brought this subject up! smile
