A simple problem I know.
I have a 10 year old BF2 which until this year has been fine.
Had an intermittent problem with the cap breather not shutting off completely and allowing a little fuel to escape when the outboard was horizontal in the boot of the car etc.

Started thinking about a new fuel cap , about £18 on Ebay etc.

Before I ordered one I though I would strip the old one down.

It's very simple , just remove the spring pin and cover spring and a couple of washers and you can see the threaded cap screwed into the main cap.

There is a circular rubber washer underneath it's head.

I replaced this with a rubber washer with a hole drilled in it which hopefully is reasonably petrol resistant.
The original one was perished.

Very easy and saved myself a little money :)

NB , the thread in the screw has a longtitudinal groove to allow the air in or out when the screw is opened.

Hopefully you have used a petrol resistant synthetic rubber, not natural rubber, or your repair may be short lived.

All the parts of the cap are available individually as spare parts.

The washer you describe is part number 1814771 and should be under £1
