Venting a 55 gal drum for diesel

[hslogger]

I just use schedule 40 PVC made into a "J" shape. Inverted and screwed into the vent hole. On the short end I have screen duct taped on to keep bugs out.
Over the years, never had a problem. I did it this way until I finally broke down and bought a dedicated rectangular tank and mounted it on a small pallet so I could load and unload with my forks instead of man handling the dang thing on and off my truck bed.

I've got a white barrel & fuel inside is nice & visible. If the barrel is collapsing that gets to the origional question in the thread. You need better venting on the barrel regardless of plastic or metal. If you seal a barrel on a hot day with low ambient pressure then it cools off it can collapse.

Mythbusters & many others have done this experiment over the years.

more extreme than normal weather swings. I'm betting plastic collapses easier, but it will also likely return to normal undamaged after its vented.

Thank you
