I have a pipe that exits from the back right of the tank and is fed down to just behind the engine - is this the fuel tank breather? Does this need to be fed into a catch tank? Or is this just an iverflow pipe for the fuel cap? Does the Monster use the fuel cap as a fuel breather too?
It may be obvious to some, but not to me - I must be fik !!!!

Strictly speaking that is not a fuel breather. Your fuel breather is built into the tank cap. That breath you mention serves to vent the overflow caused by overfilling the tank. This will spill over into the recess where the cap is located. It's the same as my MiniTwin racer - I don't bother routing this into a catch tank - I've had no scrutineering issues with this. You can do one of two things:
1. Remove the pipe and forget about it.
2. Route the pipe into a catch tank. Anything will do as long as it's resitant to petrol. For the non-return valve phone Alan Russell at A&R racing - he'll probably have them.
HTH.
