The dual-fuel tank system can save you in the case of an emergency. But if there is an issue with the fuel tank selector valve, you won’t get help in emergencies as it can’t switch you to another fuel tank. So, here in this article, we’ll talk about some Ford Fuel Tank Selector Valve Problems and the ways to solve those.
But first, let’s see what a selector valve is.
The selector valve is a part of the fuel system that helps you control the flow of fuel by shutting off a fuel tank. With its help, you can reduce the overflow of fuel by keeping a tank shut, opening the secondary tank when you need the extra fuel, and controlling the flow of fuel between two tanks.
You can see that it gives you control over the fuel system of your Ford. That’s why, when there is an issue with this valve, you can’t get the help you’re supposed to get in an emergency.
Ford Fuel Tank Selector Valve Problems and Solutions
Different types of issues might happen with the selector valve. I’m trying to discuss the common issues and help you with the solutions to those. This article will help you to know more about the fuel tank selector valves and learn what to do when any issue pops up.
Problem 1- One tank is running properly while another one is not
This is the most frequent issue you may face with your Ford truck fuel system. The reason might be the selector valve is not operating properly. But, it is not the only reason that can cause this issue. It can also happen because of the tanks themselves.
Let’s find out the solution.
Problem 2- The front tank is dominating and the rear tank is empty
Sometimes, you may face an issue where the front tank is carrying all the fuel and the rear tank is empty. In this case, you can’t save some fuel in the rear tank for emergencies. If you switch to the rear tank, it brings gas from the front tank and supplies it to the engine. Thus, you may not get sufficient fuel or strong flow as needed.
This is not an issue related to the fuel tank selector valve. But as the valve shows you the problem, I’m discussing it in this article. However, let’s try to find out the solution.
Problem 3- The fuel tank selector valve is not responding
In some cases, you may see that the selector valve is not responding. This is a problem related to the valve only.
There might be three reasons behind it- there is no valve, the system is disconnected, or the valve is corrupted.
Problem 4- One tank gets overfilled
Sometimes, you may find that fuel is transferring from one tank to another automatically and causing an overfilled tank. This is a common issue and may happen sometimes. So, don’t worry about it.
But if it happens frequently, there should be something unusual. So, you should find out the solution.
Common Maintenance for Fuel Tank Selector Valve
So, to keep the fuel tank selector valve problems away, you can perform a regular checking and cleaning process. This will help you to identify small problems before those turn into bigger issues. Besides, regular checking will let you know when and what to change if any change is needed.
Now, for you, I’m going to share how I check this part and what are the things I focus on while checking. This will help you.
Loose wire is one of the most common things to check because the wires are the most vulnerable part. So, check the wires manually to make sure that nothing is loose. Also, focus on the connections. If you find a loose wire or connection, fix that.
Go to your dashboard and check the valve control wires too. These can be lost anytime. So, checking these is mandatory. Fix if you find any issues.
Check the valves too. Release the assembly for that. You have to do this because the valve can be stuck because of dirt, dust, or similar reasons. If it is clogged, clean it properly and make sure that the valves are not stuck.
Now it is time to focus on the fuel filter. There is a huge chance that it is clogged with dirt if not inspected and cleaned regularly. If clogged, clean it. If not, you’re safe from a hassle.
As the final step, you should check the fuel tanks. Check the inlets and outlets properly. If those are clogged, clean them properly. If there is any other issue, fix it and make sure that the whole system is flawless.
Performing this simple checkup makes sure that you’re safe from the problems associated with the Ford fuel tank selector valve.
