A level sensor offset mounting mechanism that mounts in the tank fill pipe of an underground fuel tank and provides an offset for the lower level sensor portion from the drop tube. The level sensor offset mounting mechanism connects to an inner wall of the tank fill pipe by a connector. A conduit extends vertically downward from the connector to a position below the top of the tank. At the lower end of the conduit, a selectively rotatable offset device provides a horizontal offset away from the drop tube. The offset device may be rotated to an insertion position, wherein no offset is provided, to facilitate insertion, or extraction, of the level sensor into the tank. Connected to the offset device at an end distal the connection to the upper portion, the lower portion of the level sensor measures the fuel and water levels within the tank. This lower portion generally includes an instrumentation housing, a lower conduit, a fuel level float, a water level float, and a magnetostrictive device for determining the positions of the floats. The level sensor offset device is designed such that electrical wiring may be passed therethrough without allowing fuel vapors to escape the tank.
