I found an old propane tank and Mr. Buddy connection hose that I had forgotten about. The last time I used it was well over a decade ago. I did buy a Mr. Heater fuel filter. The cheap part of me wants to use the old tank and hose with my buddy heater but I am wondering if the hoses degrade over time and will end up clogging my heater, costing me more money. Any experience using an old hose? I am guessing I should replace it but wanted to check here first.
