Disclosed herein is a water level indicator for a pontoon tank comprising a float mechanism that comprises a support mechanism that does not move; wherein the main support mechanism is fixedly attached to a manway cover that protects the pontoon tank; an extension system with an extension rod adjustment system that contacts the main support mechanism at a first end and that contacts a float at a second end that is opposed to the first end; and a movable portion that comprises a plurality of levers; wherein the movable portion contacts the main support mechanism and the extension system; and wherein the plurality of levers act cooperatively to displace a gauge rod in proportion to a fluid level in the tank.

The improved float indication seal includes a float, a float rod, a level indicator, and a wall pass-through. The improved float indication seal may indicate a level of a liquid in a tanker. The float may be located inside of the tanker and may be buoyed by the liquid. The float rod may couple the float to the level indicator located outside of the tanker such that the level indicator may move synchronously with the float to indicate the level of the liquid. The wall pass-through comprising a packing ring may pass the float rod through a tanker wall. A leak at the wall pass-through may be mitigated from outside of the tanker.
