Thanks, that is what I though, I was just thrown by the VolksWorld reference to single port and not universal single/twin port.
The filter I have is actually F-415A22 and takes cartidge no C-4P2 or C-4. It doesn't seem to mention FP3 anywhere but is about the same sizea s VicPolky's.
Will this be ok? The engine is a 1600.
Is there a source for the cartidges in the UK?
Cheers,
Dave
