What causes fuel imbalance?
A fuel imbalance can occur for many reasons, including acceptable variations in the performance of fuel system components, variations in engine fuel burn characteristics, faults in internal fuel system components, or fuel system or structural faults that cause fuel to leak overboard.
What is the maximum fuel imbalance allowed between wing tanks by regulation?
453 kg.
OPERATING INSTRUCTIONS The maximum fuel imbalance between the two wing tanks is 453 kg. 2. With 1000 kg or more fuel loaded in the center tank, all pumps must be on and the crossfeed selector closed.
Where is fuel stored in a Boeing 747?
The new 747-8, like its predecessor, the 747-400, carries about 3,300 gallons of fuel in the horizontal part of the tail.
What happens if your left fuel tank is empty?
In an extreme case your right tank may be empty and your left tank may be so low as to unport the fuel pickup tube in a turn, potentially leading to attitude-induced fuel starvation (“The noisy part of the plane gets quiet until you level the wings”). I asked my instructor and this was his answer!
Why is there more fuel in the right tank than the left tank?
It is not because of turns and banks during flight. An aircraft can do steep turns all day long; loops, wing-overs, and barrel rolls, ad infinitum, with the fuel selector in the “both” position, and never have a fuel imbalance. Yet a simple training flight will usually result in more fuel in the right tank than the left.
How can I tell if my gas tank is full?
Fuel sender test. Conduct the test when the tank is lower than half to avoid splashing hot oil. Use the multimeter to check for voltage on the pins, and it has to be 5 V or 12 V on one pin. Gas gauge test. This inspection involves another voltage testing, and the reading has to be exactly the same as the fuel sender test.
Why do cars have gas tank fillers on the left or the right?
Of course, in countries with right-hand-drive cars that drive on the left side of the road, the reverse is true, which is one reason why many Japanese cars tend to have their fuel fillers on the left side of the car.
What to do when fuel is not coming out of tank?
Disconnect return line on top of tank and see if fuel is returning to tank with the truck running. If so you should have a shut off valve on the bottom of both tanks, turn them both off and remove the fuel lines. Then open valves one at a time and see that when fuel comes out of the valve it is at the same height on both valves.
Why is my fuel tank always lower on the drivers side?
Going down the road, the drivers side tank level is most always lower. In addition to the fuel lines, in the top of each tank is a pressure equalizing vent which is probably the culprit.
Why is my 98 Pete’s fuel level always lower?
NOT! From day 1, your 98 Pete’s tanks never had the same fuel levels as long as the engine is running. Going down the road, the drivers side tank level is most always lower. In addition to the fuel lines, in the top of each tank is a pressure equalizing vent which is probably the culprit.
Is the fuel level always the same in a truck?
Both lines are connected with a T fitting, ideally fuel flows to and from evenly for both tanks, levels stay the same, and they found a cure for cancer. NOT! From day 1, your 98 Pete’s tanks never had the same fuel levels as long as the engine is running. Going down the road, the drivers side tank level is most always lower.
