There are many different types and shapes of fuel tanks. In the specific case of airliners, there needs to be a method of venting fuel rapidly on the ground if the tank becomes full while refuelling at high rate. A common remedy is to drill a small hole in the fuel filler cap. The primary advantage of sub–base fuel tanks is that the system can be factory designed and assembled to minimize site work. This will keep a tank from collapsing when fuel is pumped out of it and the cross-over line keeps air pressure above the fuel at the same level so fuel should be drawn equally from the tanks, as long as you fly the aircraft balanced. The method of vehicle fuel system operation during leakage testing includes test interruption in case of detection of unintended temporary closing of the valve connected to the fuel tank. The tank must be closed to prevent contamination by foreign Restraining devices may not prevent detection of leaks or damage the venting devices and must be removed immediately after the test is completed. The 300-gram hose would be acceptable for fuel-fill and vent hoses that are not normally filled with fuel, so permeation is less of a concern. Old method resulted in fuel siphoning out the bottom vent, and blows fuel out the caps (which is really noticable on a polished wing) when the tanks are over half full. It's just a hole in the side of the tank. Fuel Tank Vent Performance Application Vent are intended to provide tank breathing, prevent fuel spillage, relieve excess pressure, and provide thermal venting in vehicle fuel tanks for which this valve is appropriate. In addition, many fuel systems contain coolers and/or 20/05/2008 · This shows an example how a fuel cell with a vented cap does not suffice in proper venting for EFI applications. 1 Analysis of a Boeing 747 Aircraft Fuel Tank Vent System.
