Fuel tank selector valves in Ford F-150 trucks
Fuel tank selector valves are used in vehicles with dual fuel tanks to switch between the two tanks. The selector valve regulates and permits fuel movement between the front and rear tanks with the use of a selector switch. When one valve is switched on, it opens one fuel tank and closes the other, and vice versa.
The Ford F-150 is a pickup truck that has been in production since 1975. It has a variety of engine options, including gasoline and diesel. The F-150 has been offered with a dual fuel tank option, which allows the driver to switch between the two tanks as needed. This is particularly useful for long-distance driving or when one tank is running low on fuel.
The fuel tank selector valve in the Ford F-150 is designed to match the fit and function of the original valve. It is engineered for durability and reliable performance, ensuring long-term functionality. The selector valve can be controlled using a selector switch, which is typically located in the cab of the truck. When the driver selects a particular tank using the switch, the selector valve opens the fuel line for that tank, allowing fuel to flow to the engine.
Some owners of the Ford F-150 have reported issues with their fuel tank selector valves. Common problems include leaks, valves not closing properly, and difficulty in finding replacement parts for older models. It is recommended to consult a mechanic or a Ford dealership for advice on replacing or repairing the fuel tank selector valve if issues arise.
There are aftermarket options available for replacing the fuel tank selector valve in the Ford F-150, including electronic versions such as the Wells FSV2K and the Standard Motor Products FV5K. It is important to ensure that any replacement parts are compatible with the specific year and model of the F-150 to avoid further issues.

Selector valves in Ford Light Trucks
Fuel tank selector valves are used in vehicles with multiple fuel tanks to switch between the tanks. Selector valves in Ford Light Trucks are a common topic of discussion among Ford truck enthusiasts and owners.
For example, owners of Ford F-150, F-250, and F-350 trucks from the 1980s and 1990s often inquire about the fuel tank selector valve and its operation. Some have issues with the rear tank not working, while others seek replacement parts for their selector valves. The 1986 F-150, in particular, is known to have a 6-port selector valve with a canister filter at the bottom and no electrical connections. This valve is prone to failure, and owners often struggle to find replacement parts.
The 1987-1989 and 1986 5.0L EFI Ford trucks have a dual-function reservoir that acts as a selector valve. The Carbonated trucks from 1985 and earlier, with 5.0L engines, and 1987 and below with 4.9L, 5.8L, and 7.5L engines, feature a 6-way mechanical valve. The switch on the dashboard allows the driver to select which fuel pump to energize.
Owners of Ford trucks with dual fuel tanks have also explored using "universal" fuel tank selector valves. Some have opted for electronic versions, such as the Wells FSV2K or the Standard Motor Products FV5K, while others have considered redesigning the fuel lines or swapping them for the '90-04 system.
Overall, the fuel tank selector valve in Ford Light Trucks is a critical component for vehicles with multiple fuel tanks, and issues with this valve can cause operational problems that require maintenance and repairs.

Selector valves in Ford Trucks with two tanks
Ford trucks with dual tanks have a fuel tank selector valve that allows the driver to choose which tank to draw fuel from. The valve is typically located on the driver's side of the frame, near the main tank, and is controlled by a switch on the dashboard. By selecting a particular tank, the switch sends power to the corresponding pump, activating it and allowing fuel to be drawn.
The fuel tank selector valve is an essential component in Ford trucks with dual tanks, as it enables the driver to utilise both tanks effectively. Without the valve, the engine-driven pump would pull fuel from both tanks simultaneously, potentially leading to uneven fuel usage and possible restriction issues.
There have been reports of issues with the fuel tank selector valve in Ford trucks. Some owners have experienced problems locating the valve, while others have encountered situations where the valve gets stuck, leading to difficulties in starting the vehicle.
Ford truck owners with dual tanks have the option to choose between an old-school manual selector valve located in the cab or an electric selector valve. The electric selector valve, such as the Pollak 6-port selector valve, is a popular choice among diesel truck owners and can be purchased and installed for a reasonable price.
For Ford truck enthusiasts, it is important to be aware of the specific parts and their compatibility when dealing with dual tanks and fuel tank selector valves. While some parts may be interchangeable between models, others might require modifications or adaptations to function properly.

Motorized electric fuel pump selector valves
In vehicles equipped with multiple fuel tanks, such as certain Ford F-150 models, a fuel tank selector valve is employed to manage the fuel supply. This valve acts as a switch, enabling the driver or operator to choose which tank the fuel is drawn from. This is especially useful when one tank is damaged or when there is a need to utilize a specific type of fuel in certain conditions.
The motorized electric fuel pump selector valve is typically controlled by a switch or a fuse, allowing for convenient and precise selection of the active fuel tank. In some cases, the valve may be located on the vehicle's frame rail, although its exact location can vary depending on the make and model. It is worth noting that these valves can sometimes malfunction or fail without notice, as reported by some Ford truck owners.
When considering replacement options, it is important to match the exact specifications of the original valve, including the number of ports and electrical connections. For instance, the E5TZ9189B Fuel Tank Selector Valve, designed for various Ford Ranger and F150 models, features six ports and is compatible with both gas and diesel engines.

Selector valves with 3 ports vs 6 ports
A fuel tank selector valve is used to switch between two tanks in a vehicle. Selector valves with three ports are available in 1/2, 3/4, and 1-inch BSPT ports, while selector valves with six ports are also available for certain vehicle models. For example, the 1984-1986 Ford Ranger and the 1985-1986 Ford F150/350 are equipped with a 6-port fuel tank selector valve.
The number of ports on a selector valve determines the number of individual circuits that can be actuated from a common input port. In this case, a 3-port selector valve can handle up to three circuits, while a 6-port selector valve can handle up to six.
It's important to note that the specific function and operation of a fuel tank selector valve may vary depending on the vehicle's make, model, and year. Some vehicles may have a motorized electric fuel pump selector valve/gauge, while others may have a manual system.
Additionally, issues with the fuel tank selector valve can cause problems with the vehicle's fuel system. For example, if the valve is not closing properly, it can lead to fuel overflowing from one tank to another.
