2. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test ...

3. Self-sealing fuel tank - Wikipedia

   en.wikipedia.org/wiki/Self-sealing_fuel_tank

   Self-sealing fuel tank. A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber ...

4. Vapor lock - Wikipedia

   en.wikipedia.org/wiki/Vapor_lock

   Air locks are caused by air leaking into the fuel delivery line or entering from the tank; common causes include the fuel tank being allowed to run dry, changing a fuel filter, or leaky fuel lines. Air locks are eliminated by turning the engine over for a time using the starter motor, or by bleeding the fuel system.

5. Diesel fuel tanks in trucks - Wikipedia

   en.wikipedia.org/wiki/Diesel_fuel_tanks_in_trucks

   All holes are temporarily plugged and the fuel tank is pressurized with air. A gauge is used to monitor the air pressure. A drop in pressure reveals a leak in the tank. Many manufacturers have adopted statistical process control (SPC) as a method of measuring the integrity of fuel tanks. Typically, using SPC, the manufacturer will test samples ...

6. Aircraft fuel tank - Wikipedia

   en.wikipedia.org/wiki/Aircraft_fuel_tank

   The Boeing 737, for example, has two systems that reduce the chance of a fuel tank ignition. One shuts off fuel pumps when fuel output pressure is low, to prevent them from heating (since they rely on the fuel itself for cooling). The other enriches the nitrogen levels in the air in the fuel tank, so there is insufficient oxygen there for ...

7. Crankcase ventilation system - Wikipedia

   en.wikipedia.org/wiki/Crankcase_ventilation_system

   A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past the piston rings.

8. Red Hill Underground Fuel Storage Facility - Wikipedia

   en.wikipedia.org/wiki/Red_Hill_Underground_Fuel...

   It consists of 20 steel-lined underground storage tanks encased in concrete, and built into cavities that were mined inside of Red Hill. Each tank has a storage capacity of approximately 12.5 million gallons. The Red Hill tanks are connected to three gravity-fed pipelines that run 2.5 miles inside a tunnel to fueling piers at Pearl Harbor.

9. Tracer-gas leak testing - Wikipedia

   en.wikipedia.org/wiki/Tracer-gas_leak_testing

   As well as airbags, the air conditioning system, fuel system, and exhaust system require testing for leaks. Pacemakers and catheters have to be tested for efficacy and longevity. On planes, tracer-gas leak testing is used to quickly and safely locate fuel leaks, [3] as well as to check oxygen distribution devices and cabin pressurization systems.
