Metal Fuel can spout

Good tight fit never leaks and I use it on 20 litre can perfect

I bought to use with B&Q metal petrol can. When pouring, the petrol leaks from around the sides of spout.

I bought this to use with old jerry cans not B and Q ones and it did not quite fit. A little dressing with a hammer and punch got it sorted and it is just perfect. I guess the new cans have a slightly different neck profile.
