What Is a Fuel Tank Selector Valve? [In-depth review]

The valve for the fuel pump selector is a switch that enables a vehicle to switch between its 2 fuel tanks. This valve enables remote access to the following distinct gasoline tanks to power the car, often known as the fuel selection valve.

If your fuel tanks are unavailable, your valve for fuel tank selectors may be failing to prevent opening and shutting inside of your fuel tank.

What Is the Purpose of the Fuel Selector Valve?

Fuel is fed into a fuel control valve using fuel tanks. The valve has a number of purposes. The first task is to operate as a valve of gasoline shut-off. This is necessary in case of an engine fire to ensure that the crew is able to avoid gasoline reaching the motor. Second, a multiple or linking tube uses the cross-feed valves to enable any tank to provide any motor.

What Is a Fuel Tank Selector Valve?

So what is a fuel valve? First, fuel will be delivered to the fuel control valve via the fuel system. This is necessary in case of a motor fire to ensure the crew does not have gasoline to reach the motor. The second feature is that the driver may select which tank the engine is supplied with.

A petcock is a tiny valve for controlling liquid or gas flow.

How does the fuel system operate in an airplane, too? In-tank fuel increase pumps, normally two each tank, are delivered to the motors by jet transport aircraft. It pumps gasoline under pressure via a shut-off valve for every motor.

where is the fuel tank selector valve? That selector valve on the side of the car on the frame rail immediately behind the cab. It cannot be simple to observe if the front tank is covered with a skid sheet.

Why are gasoline tanks exposed? Every tank is ventilated (or pressurized) in order to enable the air into the reservoir to replace burned fuel; otherwise, it would cause engine fuel to die out of hunger by negative pressure. A vent also permits air pressure and temperature fluctuations.


The Valve Selected Tank is made of a precise, 90-degree rotating bottom plug in a quality cast iron shell. The valve is constructed such that between the two end locations, there is no “blind zone” that blocks all the flow to or from the reservoirs.

The user eases the plug to transfer tanks, swings the grip to the reverse viewpoint, and compresses the plug to guarantee that the valve feeds and the reversing side is densely secured.


Standard valve building comprises a cast iron connector inside a carbon steel body. The plug is tightened using nozzles running on threaded screws.


A Tank Selector valve will be used in situations where there is no obstacle to a minor leak from the back tube to the suction tube.

When using intermittent pumping operations, the return valve connectors should be kept inundated during the tank ‘off’ cycle so that airflow from the valve return side does not enter the aspiration line. When it is not possible to keep return connections saturated, it is advised to utilize the lifting jack Sure alternative.

The packing of valve stems prevents air from entering the tubes outside the valve.

How does a fuel valve work?

The pressure regulator transfers the gasoline from the tanks into the float chambers. The float increases when fuel reaches a certain level. The needle valve shuts off the gasoline flow, maintained at the preset level, in the event the fuel boom of the float is equal with the pressure pump.

How do you turn a reserve tank on?

The button on the left underneath the bike may be switched to Major tank, OFF, and reserve tank. A tiny valve is opened in stock and enables the motor to use less gasoline than the main tank.

What does a gas tank vent valve do?

The valve for the gasoline tank discharged from the engine compartment into the air is a component of a vehicle’s evaporation emissions regulations (EVAP) systems. The gas tank valve controls the air movement into and out of a carbon canister.

FAQ (Frequently Ask Questions)

Q: How do dual gas tanks work?

A: How are twin tanks operating? A switching valve will be placed in the cab to replace your tank. Some of them are electrical with a tank-level reader. Many times an add-on reservoir has no meter, so when the principal tank runs dry it can be utilized as a range expander or reserve.

Q: Where is fuel stored on a plane?

A: It is mostly kept in the wings of passenger planes. Rubber bladders contained gasoline back in the days of piston-driven airplanes. The structural elements of the wing are now screened and employed for the formation of a tank. In the central wing under the cabin floor, many shopping aircraft also carry fuel storage.

Q: How big is a plane’s fuel tank?

A: A small airplane has a fuel capacity of as little as 4,000 to 5,000 liters. A medium-sized aircraft would have 26,000 to 30,000 liters. Breast jets would have 13,000 to 19,000 liters.


Selector valve is a part of a fuel tank, but most people don’t know what that valve is? So I am trying to inform you about this topic. I hope you are able to understand this by reading my article. After that, if you have any confusion, you can ask me in the comment section.
