Let’s discuss the details of the 1989 Ford F150 fuel tank selector valve diagram.

1989 Ford F150 Fuel Tank Selector Valve Diagram

If your 1989 Ford F150 has problems with its fuel tank selector valve, you may wonder how to replace it. Replacing the fuel tank selector valve can seem complicated, but it’s quite simple if you know what you’re doing.

Step 1: Disconnect the Battery

The first step of any automotive repair job is to disconnect the battery. That way, no matter what happens during the repair process, there’s no chance of accidentally shorting out any electrical components or causing any other type of damage to your vehicle.

To disconnect the battery in your 1989 Ford F150, start by loosening the negative terminal and then loosening and removing the positive terminal from its post. Once both terminals are disconnected from their posts, move them away from each other so that they won’t touch while you’re working on your vehicle.

Step 2: Locate and Remove The Fuel Tank Selector Valve

Next, locate and remove your truck’s fuel tank selector valve. The exact location of this component may vary depending on which model year and trim level of truck you have.

Generally speaking. However, it will be located near or around the rear axle of your truck within easy reach of where you’ll be standing when performing this repair job.

Once you’ve located it, use an appropriate wrench or socket set to loosen and remove all mounting bolts that hold it in place until it can be removed completely from your truck’s frame.

Step 3: Install New Fuel Tank Selector Valve

Now that you have removed the old fuel tank selector valve from your truck’s frame install a new one using fresh mounting bolts (if necessary). Ensure all mounting bolts are securely tightened using an appropriate wrench or socket set before proceeding with further steps.

After installation is complete, reconnect both terminals to their respective posts on your truck’s battery using a wrench or socket set for extra security before proceeding with further steps.

Ford Fuel Tank Selector Valve Bypass

The purpose of a fuel tank selector valve is to allow the driver to switch between two different tanks for either convenience or conservation purposes.

In other words, this device ensures that drivers can always access more than one tank of gasoline when needed. Most modern cars have an automatic fuel tank selector valve that switches automatically based on how much gas remains in each tank and which side has greater pressure.

However, older Ford pickup trucks use a manual selector valve, which means that the driver must manually toggle the switch each time they want to switch tanks.

Bypassing the Valve

If your Ford’s manual fuel tank selector valve becomes jammed or fails, there are still ways to bypass it and access both gas tanks if necessary. You need three pieces of equipment: two ¼ inch brass tees and one nylon hose barbed fitting adapter.

To begin bypassing the manual fuel tank selector valve, cut off both ends of the existing hose leading from one (non-working) side of the valve and attach each end to one of the brass tees using hose clamps (you may need additional fittings depending on what type of hose you’re working with).

Then attach a length of hose from one tee into a nylon hose barbed fitting adapter before connecting it back into its original position on the non-working side of the manual fuel tank selector valve; repeat this step for the remaining tee as well.

It will create a loop around the broken part of your manual fuel tank selector valve and allow you to switch between both tanks without using it.

Ford Fuel Tank Selector Valve Problems

A fuel tank selector valve is an important part that connects two or more fuel tanks, allowing fuel to flow from one tank to another as needed. While newer vehicles tend to have just one large tank that holds all the fuel, older cars like those produced by Ford often have two smaller tanks on either side of the car frame.

The selector valve is responsible for switching between these tanks when necessary. Ford fuel tank selector valves fail for various reasons, though corrosion is usually the biggest culprit.

Over time, corrosion builds up inside the valve and can cause it to become stuck in one position or prevent it from switching back and forth between tanks properly.

It can lead to major issues with your vehicle’s fuel system and cause your engine to run inconsistently or even quit altogether. 

The best way to solve this problem is by replacing the faulty selector valve with a new one. Several replacement parts are available on the market today that should fit most models of older Fords – however, double-check and ensure you get the right part before ordering anything!

Replacing the old valve with a new one should fix any issues you’re experiencing related to your vehicle’s fuel system – but if not, you may need additional repairs or servicing done by a professional mechanic. 

Fuel Tank Selector Valve Installation

A fuel tank selector valve is used to switch between two or more fuel tanks, allowing you to get the most out of your vehicle’s mileage. The valve is typically located near the fuel tank, making it easy to access when it’s time for installation.

Before you begin the installation, you must have all the necessary tools and materials. These include a wrench set, screwdriver set, drill and bit set, tubing cutter, pliers, silicone sealant, and sealing tape.

If possible, also make sure you have a manual specifically for your vehicle model to refer back to if you encounter difficulties during the installation. Depending on the type of fuel tank selector valve you purchase, additional tools may be required.

Disconnect Battery

Before beginning any repairs or installations on your vehicle, always ensure the battery is disconnected, as this will help reduce any chances of electric shock or fire risk.

Remove Old Valve

Using the appropriate tools listed above (e.g., wrench set), locate and remove the old valve from its current position near the fuel tank. Carefully examine all parts before discarding them – they may still be reusable if they are not corrupted or damaged beyond repair.

Prepare New Valve

Before installing the new valve, lightly lubricate all O-ring seals with engine oil and check that all connections are tight before proceeding with the installation.

Make sure that all components are present as per the manufacturer’s instructions before beginning installation, as missing components could cause further problems down the line.

Install New Valve

Take care when fitting the new valve into place, as this may require precise maneuvering due to space constraints or other obstructions around the area.

Once properly secured using sealant or sealing tape (if required), reconnect any hoses/piping back onto the new valve before testing its operation via multiple cycles from each side of the switch (e.g., off-on-off-on). 

Reconnect Battery

After ensuring no leaks from any connections made during installation and double-checking that everything has been fitted correctly per the manufacturer’s instructions, reconnect the battery back onto the vehicle and test the system again for full operation before taking it out on a test drive.

FAQs: 1989 Ford F150 Fuel Tank Selector Valve Diagram

What Does A Fuel Tank Selector Valve Do?

A fuel tank selector valve is a key device in any vehicle with more than one fuel tank. It allows the driver to switch between the two tanks, selecting the optimal one for their current needs based on the available fuel and amount used.

It ensures that your vehicle has the necessary power and torque. The selector valve works by causing a diaphragm to move inside of it, allowing fuel to be exposed between two chosen ports that control flow from each tank.

Where Is The Fuel Selector Switch?

It depends largely on your engine type and fuel system type. Most traditional fuel systems have the switch between the Fuel Pump and Tank to ensure optimum performance. You may find it secured to the fuel tank or sunken into the side of it.

However, use a fuel-injected engine or a diesel-powered one. You won’t find a selector valve but will instead rely on the Fuel Pump mounted internally within your vehicle’s fuel tank – this creates a more efficient onboard system and has made those types of engines increasingly popular.
