The Kenyon Homestrand pressurized alcohol stove model 550A on my recently-purchased '81 Hunter 33 wasn't working, so I removed it and the tank and took it home to clean it up (photo attached). I have been struggling to get the damned hoses back together, and in particular, the flexible hose that goes from the tank to the stove. No matter how hard I tighten the compression fittings (with teflon goo on it), they continue to leak. Can anyone tell me if the hoses need O-rings or whether there is some secret to re-attaching them?Also, if anyone else has any wisdom regarding old alcohol stoves, I'm all ears (or eyes, as it were).TIA
