So I got a gas can like this. Now my question is the small yellow cap at the back. Is that supposed to be on tight so it seals. So if I blow in the front no air should be escaping from the back cap? Is that just a hole to open when you pour gas so it doesn’t glug glug? I thought that was the point of the special self venting spout…
You’d think that self-venting design for the spout would eliminate the need for another vent. But it appears from the photo the self venting design is geared more for lower flow rate pouring; if you were trying to pour gas as fast as possible the space around the outlet might all get filled with liquid gasoline and the self-venting spout idea wouldn’t work.
You can buy those little plastic caps on ebay. I have added them to all my plastic cas cans because all the self venting spouts don’t work wort a hoot. You just drill a 1/2 " hole with a spade bit and pop them in.
E85 is rare in Canada. This “local” sports club 40 mins away sell some. I only plan to use it at drag days at my local track so having a 20 litre few weeks before for when I go will give me a full tank of E30 mix when mixed properly.
