It has a Bosch part No on it. And the tube at the bottom, I can suck and blow on. It feels like a diaphragm inside. The tube at the bottom is also threaded and adjustable - it is like a hollow bolt, with a slot in the end instead of head. There is a lock nut holding it in place against the cannister. I blew on the WUR end of the pipe and fuel came out the fuel head end - about a cannister worth. So it has to be a head of fuel sitting over an adjustable and pulsed diaphragm. But how and why?
It is of similar construction to all the other diaphragm regulators normally on the motor - ie looks like it supposed to be part of the original system. Held on by 2 of the screws the Fuel head/air flap body bolts on to. Over the back of motor below the fuel head.
