Looks like a vacuum unit on the back of the engine behind the plenum. Anyone know what it is. The hose was off mine probably from when I did the fuel hoses last year but it was running OK.

If it's a small bore hose (5 or 6 mm ID or so) than it will be to the fuel regulator as stated above. If the hose is larger and pre-formed (maybe 20mm ID), then that'll be the idle air bypass circuit that is controlled by the stepper motor.
