That's my plan. I haven't dug back into this lately as it hasn't been a huge priority but I would still like to have that confirmation of what this was. The last few outings I've ran the stove I've just used 1# cylinders and one will keep us going for lots of cooking all weekend long. I was planning to take the tank to the propane place to check out. Covid has changed how the local propane place handle refills, tank recertification, and exchanges. Long story short I'm not sure I have a local place that will do this anymore, at least until covid is no longer a 'thing'. The typical refill station (u-haul, tractor supply, etc.) won't do any other services than refill.Sounds like the biggest variable to eliminate at this point is a flashlight shot looking inside that tank with the valve taken out
I did change hoses around post #47. I looked into a filter but have not concluded that one was needed.Just change hoses or cob up a filter setup like Mr. Buddy does.
