Ford Fuel Tank Selector Valve Problems With Solutions

The fuel tank selector valve on a Ford is usually attached to a lever located under the driver’s seat. When the lever is turned, it gives a warning to the selector valve, which in many situations closes one of the fuel tanks.

Ford produces a wide range of automobiles, including the Ford F-150, F-250, and others. It should be noted that since it has many working versions, its problems would be unique. For automobiles, you may experience the following general problems:

  • The selector valve malfunctions and the fuel tank does not open or close.
  • In the initial location, the selector valve does not work.
  • A problem with the fuel system.
  • The fuel tank has been overfilled.

Problem 1: One tank is having problems, while another is doing admirably.

This is a general problem with the Ford fuel tank selector valve. The selector valve consists of six valves in total and has various fuel sending and returning functions.

The fuel tank cannot open or close properly if the selector valve fails. In this case, regardless of whether the other fuel tank is working or not, only one fuel tank is responsible for the job.


  • First, inspect the fuel selector valve switch.
  • Second, inspect the wires to determine if they are even or loose.
  • Third, if it is accessible and there is no difficulty, you should purchase a small motor. This has everything to do with the selector valve switch. As a result, you must correct it.

After that, you should be able to easily solve this problem.

Problem 2: When starting your Ford truck, the selector valve cannot react.

These problems can arise from time to time. This happened on an old Ford truck.

You may run into this problem if you buy a used Ford truck and the previous owner disconnected the selector valve somehow. In this scenario, you would drive straight into the front fuel tank, as the vehicle is unlikely to fire.


  • To begin, remove the selector valve.
  • Secondly, instead of choosing a valve, you can increase performance by using a check valve.

In particular, if you want to buy a vehicle from the Ford fuel tank selector valve, you can do it fresh.

Problem 3: Fuel system problem in ford truck

If the front fuel tank is functioning properly on a dual tank vehicle, there is no fuel in the rear fuel tank. Since the switch, together with the rear fuel tank, is locked, gasoline is drawn from the front fuel tank. As a result, bad fuel may come out of it.


  • First, check if the rear pump is operational. The switching valve prevents the reservoir pump from operating. Therefore, if it is not working, there is no way to switch.
  • Second, unplug the pump switchboard and put the switchboard lever in the back position.
  • Third, to get the rear reservoir to work, you must switch the lever.
  • Fourth, you can switch to the front reservoir. If there is no response, it needs to be replaced.

Problem 4: Overfilling of the fuel in the tank

It is normal to refuel when fuel flows from the rear tank to the front tank.


  • To begin with, rebuild the selector valve.
  • Secondly, you should use the second alternative, which requires the replacement of the fuel pump instead of the fuel tank.
  • Third, you can use another unique option. What exactly is it? You can remove the two components of the front fuel tank, including the reversing valve. It must be the one to go.
