Fuel Tank Selector Valve Problems with Solutions
A fuel tank selector valve usually connects with a switch sometimes found under the seat of the driver. When the switch is flipped, it sends a signal to the selector valve to switch from one tank to another. This valve is usually found in Ford trucks.
There are many models of Ford trucks such as F-150 and F-250. These trucks use a dual fuel tank system. This is why they have a fuel tank selector valve. There are some common problems associated with this system.
The most common include:
- Fuel tank overfilling
- Fuel system problem
- The selector valve has problems resulting in the fuel tank not opening or closing
- The selector valve refuses to work in the starting position
Problem 1: Faulty Tank
One of your tanks has a problem when the other is working well. It is a common problem on Ford trucks. In general, a selector valve comes with six valves. The selector valve has multiple return and sending functions. If the selector valve has malfunctioned, the fuel tank will not close or open properly. In this case, you can only access one fuel tank.
There is a step by step solution you need to follow:
- Check the fuel tank selector valve switch
- Check the wire to ensure the wire cable is not loose
- Take close look or let a professional check your small motor if you haven’t found any problems with the above items. It is connected to the valve switch and repairing it may solve the problem.
Problem 2: Valve Doesn’t Respond When Starting Your Car
This is a common problem in old Ford trucks. You may face this problem if you bought a second-hand Ford truck. It may be caused by the previous owner removing the selector valve. If this is the case, you need to use the front tank only.
The following steps can help you remedy this problem:
- Remove the selector valve
- Add a check valve. It may perform better than a fuel tank selector valve
- Replace the old valve with a new fuel tank selector valve compatible with your model
Problem 3: Fuel System Failure
In dual tank trucks, the rear tank may not have fuel, but the front one does. Sometimes the switch fails causing fuel from the front tank to move to the rear tank.
Fuel moving from one tank to another without the driver’s action is a common Ford truck problem. The solution is:
- Check if the rear pump is running. The pump doesn’t work with the selector valve. If it isn’t running, you won’t have the option to switch from one tank to another
- Unplug the frame of the pump and switch to the rear tank
- Run the rear tank by switching on your vehicle
- Switch to the front tank. If it doesn’t respond, it means you have to replace your fuel tank selector valve
Problem 4: Overfilling
Sometimes fuel may leave the rear tank and move to the front tank.
There are several methods you can use to solve this issue:
- Rebuild the selector valve
- If the fuel pump has malfunctioned replace it
- Remove the selector valve after ensuring you can use one of the tanks, preferably the front one
The above problems are common dual tank problems in Ford trucks. Other issues may arise. For example, in the 1996 F-150 models, sometimes fuel may leak. It happens when both tanks are filled and you start using the rear tank.
The leak usually occurs on the front tank. If you don’t know how to go about finding a solution, consult a certified mechanic.
Answer: Yes, it is. You need to connect the return and feed from or to the engine to the return and feed from or to the front tank. A few hose clamps and two short fuel hoses are enough to bypass the selector valve. The downside is you have to cut all the connectors. This means reinstalling the selector valve back later will be a nightmare.
Answer: In most vehicles, the selector valve is located on the driver’s side on the frame rail, just behind the cab. You may not see it if your front tank has a skid plate over it.
Answer: There is a switch on the dashboard. You use it to select the tank the vehicle will use when you are driving. The fuel gauge switches when you switch to the other tank. You drive until the tank you are using is almost dry. Switch to the other fuel tank without slowing down. Don’t wait for the tank to be empty because your engine will run out of fuel before you switch.
Answer: It is a device that is designed to allow a driver to switch between the two tanks found in some vehicles. The majority of Ford trucks have dual tanks. A switch is connected to the selector valve. It is usually found to the right of the steering wheel or under the driver’s seat in most dual tank vehicles.
A fuel tank selector valve is a crucial part of any dual tank system. If it malfunctions, you need to replace it before you encounter more problems. Use the list above to choose a fuel tank selector valve. The above information also gives you insight into common problems and their solution.
