How to stop plastsic fuel can lid from leaking?

[sofonamy]

Hi,

I have some of the Supercheap plastic fuel cans but it seems to me that no matter how tightly I do up the lids they always leak fuel.

I have a couple of different makes, but they all seem as bad as each other.

Has anyone come up with a way to stop this happening?

Thanks in advance.

There's a crack in your canister, am I right?

It would be best if you poured gasoline into a glass jar. Next, add the foam to the jar (it will quickly dissolve and become a homogeneous mass). The glue is ready! Cleaned the crack and placed it on the plastic canister with sandpaper. We take fiberglass and cut off a piece that will cover the crack from all sides by two centimeters. Then we smear the place of damage with glue (the glue should get inside the crack) and apply a patch of fiberglass, and we also thoroughly smear it (the glue should soak into the patch). But it is better always to have a special glue for plastic and aluminum can crusher at home so that you can seal the canister or vice versa, throw out cans and under beer easily.
