Fuel tank selector switches: location and issues
The fuel tank selector switch, in vehicles with dual tanks, is located at the front edge of the forward tank. The switch on the dashboard controls the selector valve, telling it which tank to use. The selector valve regulates and permits fuel movement between the front and rear tanks. When one valve is switched on, the other is closed, and vice versa.
If you are experiencing issues with your fuel tank selector switch, there are some troubleshooting methods you can try. First, check if the issue occurs with the selector switch in just one position, either front or rear. If so, the problem is likely between that specific tank and the selector valve. Inspect the supply line from the tank to the selector valve; if it is not damaged, kinked, or obstructed, the valve itself may be faulty and need replacing.
Another method is to perform a "bucket test", which involves bypassing the fuel tank(s) and tank-to-selector valve supply lines to isolate the issue. If you are experiencing fuel system problems such as electrical problems with the coil, internal leaks from the valves, or external fuel leaks, these could be indicative of a problem with your fuel tank selector valve.
In some cases, there may be a filter inside the switching valve that is clogged, resulting in a total loss of fuel. You can try to temporarily change or swap the supply lines to the valve to determine if the problem lies within the valve.

Dual tank systems: transferring fuel
The 1989 F250 has dual tanks and a fuel selector valve. The fuel tank 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.
Dual tank systems in Ford trucks work as follows: the fuel delivery module (FDM) is in each tank, and it contains the fuel pump, gauge sender, and a check valve. When the fuel pump for a tank is turned on, the check valve for the same tank opens, and the gauge switches to read that tank. The check valve can sometimes leak, which results in fuel returning to both tanks.
The sender assembly handles the switching of the fuel through internal valves. The fuel intake sock is a screen located on the intake side of the fuel pump and is part of the fuel pump assembly. The system also contains a filter screen on the fuel rail port of the injector, which is part of the fuel injector assembly.
To fix a fuel transfer problem, you need to replace the fuel delivery module in the front tank. If you want to run just the rear tank, you need to plug both fuel lines at the front tank.

Fuel gauge issues: troubleshooting
A malfunctioning gas gauge can cause you to run out of fuel unexpectedly, potentially causing long-term damage to your car. This includes increasing fuel pump wear and clogging fuel system components. The gas gauge system consists of the gauge, sender, and circuit. Issues can arise from any of these components, often due to sending unit failure, circuit problems, gas gauge failure, or instrument cluster failure.
If your gas gauge is stuck on empty, you may be experiencing one of several common issues. For example, if you have just filled up your tank and your fuel gauge still shows empty, you know there is a problem somewhere. However, the gauge might show full even after you've driven a long distance, which is also a sign that something is wrong.
To diagnose gas gauge issues, perform tests on the instrument cluster, fuel sender, and gas gauge using tools like an electrical wiring diagram and a digital multimeter. Set the multimeter to 20V DC and test the wiring going to the gauge. It should be receiving 12 volts. If the voltage is good, the gauge is faulty and should be replaced. If the voltage is low, complete the rest of the diagnosis to discover if it is a wiring issue. If the wires are corroded or the insulation is worn down, replace the wiring.
On older vehicles, the fuel gauge will usually have two terminals. One of these terminals receives 12V of power when the ignition is turned on. The other terminal is the sending wire from the sending unit. The gauge itself is then grounded. If you do not have 12V at the power wire, the lack of power will need to be troubleshot. You can also test continuity between the sending terminal at the dash and where it connects back at the tank. If you have no continuity, there is a break in this wire somewhere.
Circuit problems can also cause the gas gauge to stop functioning normally. Depending on the location of the fault, the fuel sender may not have a source voltage, the gas gauge may have no fuel sender voltage, or the ground for either one may be interrupted. Loose connections and corrosion can also cause problems, particularly in the fuel pump module, which is usually exposed to the elements.

Clogged Fuel Injectors
Fuel injectors play a critical role in delivering fuel to the engine. Clogged injectors can disrupt fuel distribution, leading to rough engine performance and increased fuel consumption. Regularly inspect and clean the injectors to prevent buildup. For severe clogs, replacement may be necessary.
Fuel Contamination
Contaminants in the fuel, such as water, sediment, or microbial growth, can cause significant issues in the fuel system. These contaminants can lead to corrosion, clogs, and reduced fuel quality. To prevent and mitigate fuel contamination, use fuel treatments that prevent water accumulation and microbial growth. Keep your fuel tanks topped up to minimize condensation, and regularly inspect and clean your fuel tanks.
Fuel Line Leaks
Leaks in the fuel lines can lead to fuel wastage, fire hazards, and decreased engine performance. Leaks can occur due to corrosion, vibrations, or physical damage. Regularly inspect the fuel lines for signs of damage and secure them properly to prevent excessive vibrations. Replace damaged sections with corrosion-resistant materials if necessary.
By promptly addressing these fuel transfer problems and implementing the suggested solutions, you can help ensure the smooth operation of your 1989 F-250's fuel system and maintain its reliability.
