TX heat will push unvented gas cans gas past valves. 3 gallons in a 2nd tank was gone today with all indications it was pushed passed the coupling and out the bilge drain while in storage. jow

You sure it's in the bildge?The air/fuel wouldn't expand that much to push 3 gal. out of the tank.
I went fishing andwas positive I had 18 gal in a spare tank.I think what happened was the Ethanol ate my hose from the tank to the manual valve,then it started leaking and siphoned off all 18 gal.
Thank G that I had Tow Boat Insurance.We ran out of gas 14 mi out in the ocean.Or maybe I used it.Old and suffering from CRS.J

This is the 2nd time this has happened.

1. The first I could understand. I left a quick-coupling and a piece of hose on a tank while changing fuel lines. About a gallon was pushed passer the open valve before I spotted the problem.

2. The second waste of gas was past a closed valve (with signs the gas was pushed out) and plenty pressure was released when I vented the can.

3. I usually will not leave the cans vented fearing moisture. This has taught me a lesson. Will the open vents allow moisture to enter the cans? Thanks, jow

This was during 90 + degree weather a few weeks ago. This had never happened that I know of. BUT! In 100 degree weather + once in the mid 80s we heard hissing noises while driving and pulled over to find the truck and boat's tank's caps were releasing pressure. My concern is a release system, which I feel my next 1993 Explorer had. It world flood when I over filled it in 100 degree weather (after a fill-up and coasting to my 1st stop). I have an 07 V6 4Runner after 15 years with my Explorer that my boat and I are having trouble adjusting to (towing and etc. due to wanting to continue with a solid rear axle). The Explorer knew its way home. LOL. jow
