Cars that use seal (#293-410) and lock ring (#360-665) to retain the tank sender unit in the gas tank can suffer from leaks in this area. This is particularly common when a new tank is fitted and the seal and lock ring are replaced as a matter of course. The most common reason for a leak here, is an incorrect sequence of assembly.
