Has anyone got......
 

....the little brass nipple/union/takeoff thingy from the inlet manifold of a carby monster going spare or available for a borrow please?

These are where the hoses for the vacuum fuel pump go onto, I think.

I need to check the balance of the throttle bodies on a Monster 800 and the blanking screw is directly behind a frame tube so I can't screw in any of the takeoff extenders that I've got.

This assumes that the thread is the same on both injected blanking plug and carby outlet, but without the latter I can't tell.......

Thanks, Paul
