Just so you do not experience the same issue(s) that I have with your scepter cans, take the time and confirm what you have under the lid. This my experience, I bought 4- OD diesel scepter cans a few months back after confirming the use for gas was not an issue. Just recently, I had the time to clean them, filling each of them with gas and stabil and stored them outside the garage in a safe area. In my travels, back and forth from the house to the garage, I noticed swelling (no big deal, common atomspheric result, heat/cool, etc....) Then I decided to try my set-up with the MFC can and a super siphon. I had a bear of a time trying to remove the lid from the can, upon applying additional (excessive) force, I could remove the lid and the seal promptly fell out on to the driveway
. I inspected the lid and found that the flange which captures the seal and ensures alignment was torn. After googling the problem I discovered my intial oversight from this warning below.

Fortunately, Kurt at expedition portal was able to deliver new viton seals, flanges and red straps, but these parts are becoming near impossible to source.
