The fuel filter in a 1999 Ford Explorer is positioned in the line leading from the gas tank to the engine. It prevents contaminants from getting inside the engine, which could cause a loss in performance and potential damage to the cylinder lining. To replace the fuel filter, you will need a fuel filter removal tool, such as a 5/16 Fuel Filter Remover, which can be purchased at a local parts store. You will also need to ensure there is no fuel pressure in the system before beginning. The process involves releasing the fuel pressure in the fuel line, unhooking the fuel lines from the filter, and then installing the new filter. The fuel lines are locked in place with stainless steel spring clips, which may need to be lubricated to release.

What You'll Learn
The fuel filter is located under the vehicle, below the driver's door
The fuel filter in a 1999 Ford Explorer is located under the vehicle, below the driver's door. It is mounted in the frame rail and snaps into a metal spring clip on the frame.
To replace the fuel filter, you will need a set of metal line disconnect tools. The fuel lines are locked in place on the filter with two stainless steel spring clips, which must be unhooked. Spray WD40 or brake/parts cleaner into the fitting to help lubricate it and flush out any dirt. Once the fuel line moves in and out easily, put the disconnect tool into the end of the filter and push the line in, pushing the disconnect tool in at the same time.
It is important to ensure that there is no fuel pressure in the system before beginning any work. Park the truck with the gas tank below the level of the fuel filter. With the engine running, pull the fuel pump relay or trip the inertia switch to release the fuel pressure in the fuel line.
The whole process can take some time if it is your first attempt, but with experience, it can be completed in a matter of minutes.

You will need a 5/16 fuel filter remover tool
To replace the fuel filter on a 1999 Ford Explorer, you will need a 5/16 fuel filter removal tool. This is a specialty tool that will help you disconnect the fuel line from the connector without causing any damage. The tool ensures that the right amount of pressure is applied to the connection, allowing for easy disconnection.
You can purchase a 5/16 fuel filter removal tool from various retailers, including AutoZone and Amazon. The tool is typically made of metal, with some options constructed from anodized aluminum. The price of the tool varies, but it is generally inexpensive, ranging from $8.37 to $20.
When using the 5/16 fuel filter removal tool, it is important to follow the correct procedure. One user recommends putting the tool on the fuel filter tube and pulling the gas line towards you onto the tool, then immediately pushing it away. This motion may need to be repeated several times before the line disconnects.
Additionally, it is crucial to ensure there is no fuel pressure in the system before beginning any work. This can be achieved by pulling the fuel pump relay or tripping the inertia switch to release the fuel pressure in the fuel line.
By using the 5/16 fuel filter removal tool and following the recommended steps, you can safely and effectively replace the fuel filter on your 1999 Ford Explorer.

Disconnect the fuel lines
Disconnecting the fuel lines of a 1999 Ford Explorer can be a tricky process, but with the right tools and steps, it can be done efficiently. Here is a detailed guide on how to do it:
Firstly, it is important to relieve the fuel system pressure. This can be done by pulling the fuel pump relay or tripping the inertia switch with the engine running. This crucial step ensures that the fuel lines are depressurized before any disconnection or work is performed.
Now, let's move on to the fuel lines and the filter. The fuel lines are locked in place on the filter with two stainless steel spring clips. These clips need to be unhooked, but before attempting to remove them, it is advisable to spray WD40 or a brake/parts cleaner into the fitting. This helps to lubricate the connection and flush out any dirt or rust that might be preventing the clips from releasing smoothly.
Once the connection is lubricated, you may need to push the fuel line into the filter a bit to create some clearance for the clips. With the right tool, such as a 5/16" fuel filter remover or a similar metal line disconnect tool, push the tool into the end of the filter, and simultaneously push the line and the tool in, allowing the clips to release. Leaving the filter in its retainer while releasing the fuel line can provide some extra stability during this step.
In some cases, the fuel lines may have spring lock couplers. If your Explorer has these couplers, the process is slightly different. First, check for any damage to the garter spring and "O" rings, and replace them if necessary. Then, wipe the ends of the lines with a clean cloth and lubricate them with clean refrigerant oil. Locate the White indicator ring, if equipped, and insert it into the cage of the male fitting. Push the fittings together with a slight twisting motion until you hear a click, indicating that the connection is secure.
Disconnecting the fuel lines on a 1999 Ford Explorer requires patience and the right tools. By following these steps and paying close attention to the specific connections and clips, you can safely and effectively disconnect the fuel lines during a fuel filter replacement.

Remove the old filter
To remove the old fuel filter from your 1999 Ford Explorer, you will need a 5/16" fuel filter removal tool, which can be purchased at a local auto parts store for around $13. You will also need a set of metal line disconnect tools, which typically cost around $20.
Before beginning the removal process, ensure there is no fuel pressure in the system. Park the truck so that the gas tank is below the fuel filter. With the engine running, pull the fuel pump relay or trip the inertia switch to release the fuel pressure in the fuel line.
Now, we can begin removing the old fuel filter. The fuel lines are locked in place on the filter with two stainless steel spring clips. These must be unhooked before proceeding. If the spring clips are clogged with dirt and rust, spray WD40 or brake/parts cleaner into the fitting to help lubricate it and flush out any dirt. Once the fuel line moves in and out easily, put the disconnect tool into the end of the filter and push the line in and the disconnect tool at the same time. You may find it easier to leave the filter in its retainer while releasing the fuel line.
The spring lock coupling is held together by a garter spring inside a circular cage. To separate the coupling, the flared end of the female fitting must be slipped out from behind the garter spring inside the male fitting's cage. Additionally, most vehicles have a horseshoe-shaped retaining clip that must be removed to fully unlock the coupling.
