Replacing Fuel Filter: Ford E-150 Guide

Changing the fuel filter on a Ford E-150 Econoline van is a relatively straightforward process. The fuel filter is located under the vehicle, on the driver's side frame rail. To replace it, you will need a 5/16 Fuel Filter Remover tool, which can be rented or purchased from most auto parts stores. The procedure involves depressurizing the fuel system, disconnecting the fuel lines, sliding out the old filter, and installing the new one, ensuring the arrow on the filter points towards the front of the van. The fuel pump fuse should also be removed and reinstalled during the process. It is important to exercise caution when working with gasoline due to its toxic and flammable nature.

The fuel filter is located under the Ford E-150

The fuel filter on a Ford E-150 is located under the vehicle, on the driver's side frame rail. The exact position depends on whether the fuel tank is in the middle or the rear of the vehicle. To access the fuel filter, you will need to park your van on a flat, level surface and engage the parking brake.

Once you have located the fuel filter, you will need to relieve the pressure in the fuel lines. To do this, open the hood and locate the fuse panel near the battery. Open the panel and remove the fuel pump relay. Then, start the van and allow it to run until it stalls. After the engine stalls, crank the engine for about five seconds to ensure the fuel injection supply manifold pressure has been relieved.

Now that the pressure has been released, you can disconnect the fuel tube push connect fittings from the fuel filter. Be sure to slide the fuel filter out of the bracket and follow the installation instructions for your new fuel filter.

It is important to note that you will need a special tool, a 5/16" Fuel Filter Remover, to complete this task. This tool can usually be rented or purchased at a local auto parts store. Additionally, always exercise caution when working with gasoline as it is toxic and flammable.

How to disconnect the inlet and outlet lines from the filter

To disconnect the inlet and outlet lines from the filter of your Ford E-150, follow these steps:

First, ensure your van is parked on a flat, level surface and engage the parking brake. Open the hood and locate the fuse panel near the battery. Open the panel and remove the fuel pump relay, which should be labelled.

Next, start the van. Once it stalls, the pressure in the fuel lines will be released. Remove the keys from the ignition and reinstall the relay.

Now, locate the fuel filter underneath the van, along the frame rail. You can find it by tracing the fuel lines to the driver's door.

To disconnect the inlet and outlet lines, you will need a quick-disconnect tool. Place the tool over the inlet fitting and pull it toward the filter to release the line. You can use a piece of masking tape to mark the inlet line. Then, pull the outlet line off the filter using the quick-disconnect tool.

Once the lines are disconnected, you can slide the filter off the mounting bracket by loosening the retaining bolt with a socket wrench.

Removing the old filter from the mounting bracket

To remove the old fuel filter from the mounting bracket of your Ford E-150, follow these steps:

Firstly, ensure your van is parked on a flat, level surface and engage the parking brake to prevent any accidental rolling. Next, open the hood and locate the fuse panel near the battery. Open the panel and remove the fuel pump relay, which should be labelled. Now, start the van to depressurise the fuel system. Once the van stalls, the pressure in the fuel lines will be released. Remove the keys from the ignition and reinstall the relay.

At this point, you can find the fuel filter underneath the van. Trace the fuel lines to the driver's door—the filter is located along the frame rail. Place a quick-disconnect tool over the inlet fitting and pull it towards the filter to release the line. You can now slide the filter off the mounting bracket. Loosen the retaining bolt with a socket wrench and slide the filter away from the bracket.

You are now ready to mount the new filter to the bracket.

Installing the new filter and tightening the bracket

Now that you have removed the old fuel filter, you can install the new one. First, mount the new filter onto the bracket. Ensure that the arrow on the new filter is pointing towards the front of the van, as this indicates the direction of fuel flow.

Next, tighten the bracket with a socket wrench. Once the new filter is securely in place, you can reattach the fuel lines. Remove the masking tape from the inlet line and push it onto the fuel filter. You should hear it lock into place once it is pushed far enough. Repeat this process for the outlet line.

Now that the new fuel filter is installed, start the van and let it idle for about five minutes. During this time, carefully observe the fuel filter and surrounding area for any signs of leaks. If no leaks are detected, turn off the engine and re-install the fuel pump fuse.

Note that the van may not start immediately, as the fuel pump needs to be primed. To do this, turn the ignition key to the "start" position and let the pump run for about five seconds. Once the pump is primed, turn the key again, and the van should start.

Re-installing the relay and priming the fuel pump

Once you have finished replacing the fuel filter, you will need to re-install the relay and prime the fuel pump.

First, locate the fuse panel near the battery in the engine compartment. Re-install the relay by opening the panel and plugging the fuel pump relay back in.

Next, start the van to depressurise the fuel system. Once the van has stalled, the pressure in the fuel lines will be released. Remove the keys from the ignition and turn the ignition switch to the OFF position.

Now, you will need to prime the fuel pump. Do this by turning the ignition key to the "start" position and letting the pump run for five seconds. Then, turn the key once the pump is primed, and the van will start.

Safety Warning: Use caution when working with gasoline as it is toxic and flammable.
