Inspecting and Testing Removable Rigid Fuel Tanks

How should you inspect a removable rigid fuel tank for leaks?

A. Cap the tank tightly to prevent leakage
B. Utilize air gaps in rigid containers
C. Use water only for identification of leaks
D. Do not worry about leaks as it is common

Answer:

To inspect a removable rigid fuel tank for leaks, do not cap the tank tightly because it can cause the tank to leak or burst due to compression resistance. Instead, utilize air gaps in rigid containers that allow expansion and contraction.

When inspecting a removable rigid fuel tank for leaks, it's crucial to follow a systematic procedure for accurate results. Firstly, one should not try to cap the tank tightly to prevent overflow as it leads to leakage either around the cap or bursting of the tank. This occurs because constricting the expanding gas is equivalent to compressing it, and both liquids and solids resist compression with large forces.

Thus, these rigid containers have air gaps that allow them to expand and contract without causing stress. Place the fuel tank in a large tray with raised sides, like a baking tray. Small volumes of lighter fluid, penetrating oil, or cooking oil can be used with water to identify the leakage points by observing where these fluids seep out.

For documentation, using a camera to capture evidence of the leaks can be helpful.
