Hunsaker Fuel Jugs Vent mod?

I have three of the 7 gal Hunsaker fuel jugs, they work great, fill quickly and dump fast with the mouth cut open.

Im having issues with them venting now that its hot. When you have the hose kit installed the top of the handle tube is the vent. The pressure in the main tank will push like 3 gal of fuel out the vent if it gets hot. This happened to me while at work last week and it spewed gas on my truck and surrounding cars. Its really dangerous.

We need a second vent in the hose kit that can vent the larger chamber.
Ive been keeping my host kit cap loose but it still builds up pressure. I was gonna drill a small bleed hole in the top of the hose kit but am looking for better ideas that wont let dust in.

I've been able to get away with keeping the main tube cap loose.

I learned that lesson at KOH when my tanks self-vented right under the 5th wheel portion of my trailer, next to a running generator.

You're right, it's extremely dangerous.

The team I pit for in baja uses dry break connectors and have the same problem. When in transit, or sitting in the pits they usually open the dry breaks, and string a zip tie through the opening to hold it open just a touch.

Had the same issues, we have vent caps that have a little plastic snap on covers that we leave open.

Never open the vent first, always the main cap. should keep the fuel in the can but shoots the cap a ways.

The trouble with leaving the vent open to fresh air is the rate the gas looses Octane. In the two stroke world they claim that 30 days is enough to reduce octane something like 10 points. I can't remember now but that info is around on snowmobile websites for sure.

if I have to choose between losing octane and pouring gasoline all over the floor of my shop, I'm going with the octane loss.

I always leave the top cap loose as well, Im going to forward this on to hunsaker so he can see if there is a way to work in an additional vent.

If we had two vents that were identical, the one on the handle could still blow first and have the same issue.

The handle vent should be a screw in plug, the main jug should have the safety pop off vent.
