My 1939 R51 fuel petcock bowl doesn't seem to have a filter in the bowl it like most seem to. Nor does it seem to have two holes to/from the bowl from the petcock body (one to feed each side of a filter) like some I've seen - it only has one hole in the petcock that flows into the bowl.

Surely if it has a bowl is should have a filter or is it just there to catch heavier particles or 'leak-by' when the fuel tap is off?

Yes it should have a filter, I had an original fuel tap with my R51, and it had a filter. Sounds like yours may not be correct for the bike?

I expected a bowl type filter.

When I took a better look this weekend there is a flat disc type filter with a hole in the centre for the infeed on the underside of the petcock body and the out hole covered by the disc filter. Maybe I need better glasses!
