Manual Tank Gauging Procedure

Description: This video shows how to manually gauge the level of both fuel and water in your tank. This procedure is beneficial in verifying the accuracy of your clock gauge. Summary: For this procedure, you will need a gauging tape, a brass plumb bob, water gauging paste and a rag. To begin, locate the gauging hatch and remove its cover. After the cover is removed, apply paste to plumb bob. Note that when the water gauging paste comes in contact with the water, the paste will turn color. Be sure to attach the grounding strap to the tank to remove any static electricity flow. Drop plumb bob into tank until reaching the bottom then check if there has been color change on plumb bob. Repeat this process again to check if the depth is the same as the first. Seal and replace cover following dipping procedure.
