I have a 25L Quicksilver fuel tank for my Mercury 15hp 2-stroke outboard
Question is when stored containing fuel, should the vent be open or closed?
I ask because when not in use I always close it, but I noticed a smell of petrol yesterday and the fuel line had disconnected itself from the tank and fuel had leaked onto the floor.
I also wondered if this had anything to do with E10 fuel having degraded the line in some way
I store mine outside (of course), out of the sun and the vent very slightly open. E10 goes off pretty quick they say so I would not keep it long or use it in the car/lawnmower etc or add stabiliser.
Thread has been covered before. Consensus seems to be - to keep it closed. No reason to vent it during the winter, obviously keep out of an area where they’re are fluctuations in temperature if stored inside. A garden shed away from the house seems reasonable if more than 30 litres.
I leave mine very slightly open. I've always been worried about large changes in pressure making something go pop.
I think it's a binary state. Open or closed. Slightly open, is still open.
Open = water vapour can get in, mix with ethanol, fuel go off.
Closed = pressure could build in the tank. I very much doubt that it can force off a properly connected fuel line. So either it was it properly connected, or is damaged.

completely agree.
