Fuel tank and 2 aliens, '89 B2600i
So I removed the bed on my Mazda to swap out the fuel tank/pump only to find two alien devices on top of the fuel tank (circled red in the pic). I've never seen anything like them, so I a haven't a clue as to what they are. Anyone know what these device are and what purpose they serve? Finally, will they also need to be replaced?
