Hello All.

Can someone Identify the small black "Sensor " on the back of the Fuel Distributor for me ? (89 300 CE 3.0). It's held on by 2 torx or hex head bolts.

It seems I have a little "wetness" and a small drip of fuel from here. Is there a gasket behind it? I don't want to pull it off until I have the new one in hand (or gasket if that all it requires). Anthing special I need to know or is this one of those MB things that is'nt as simple as it appears..?
