Mann & Hummel Air Filter Gaskets Question

[Le Belge]

Hi,

Can anyone tell me the difference between no.5 and no.6 on the pic below?
I have one of the two but I can't tell which one...
If anyone has pictures of both gaskets (side by side), or the diameters, that'd be very helpful.

Many thanks,
Jeremy

Jeremy:
It's been decades since I had an early 912 with the Mann & Hummel air cleaners, but IIRC the small one (5) goes on the tube before the element goes on and (6) the larger one seals the big can when it clips onto the base unit (mounted on the carb - see photo) BTW our host stocks both of these parts.

Hi Bill,

Thank you so much. That's exactly what I needed to know.

Kind regards,
Jeremy
