fuel filler vent

[Rickent]

Help.

This is my fuel cap, inside the vent there should be two pieces of flame arresting gauze.

One piece is missing. I am sure it will be a fail on BSS, so how is it replaced.

There appears to be a large nut on the inside of the filler cap so this would suggest that the piece containing the vents is removable. Is this the case and where could I source a replacement.

Other chandlers are available and may even be cheaper!!  https://www.limekilnchandlers.co.uk/brass-1/2-breather.html

To fit:  Undo big nut inside cap, remove old breather.  Fit new.   Tighten nut.   A fibre or copper washer between the breather and the filler cap would be  a good idea as you need to get a good seal or water will run into your tank, though it may do anyway as it seem the vent holes are in the groove for the opening tool.

Thanks BEngo, all makes sense now.
