Replacing Fuel Pump In 2000 F150: Step-By-Step Guide

If your 2000 F150 is having trouble firing up or is experiencing strange idling, it could be that your fuel pump is on its last legs and needs to be replaced. The fuel pump is located inside your fuel tank and delivers fuel to the engine. You can either attempt to replace the fuel pump yourself or take your car to a mechanic or dealership.

If you choose to replace the fuel pump yourself, you will need to remove your truck bed or fuel tank. Removing the fuel tank requires siphoning gas and using a car jack and several stands, while removing the truck bed involves disconnecting the bed and tailgate lighting, removing wire harnesses, and lifting the bed off the truck.

Once you have accessed the fuel pump, you will need to disconnect the fuel lines and electrical connectors before removing the old pump and installing the new one. Finally, you will need to reassemble your car by putting the truck bed or fuel tank back in place and reconnecting all the necessary components.

Removing the fuel tank

This step requires siphoning gas and using a car jack and several stands. You will be spending a lot of time underneath your vehicle and you will need to remove all lines that connect the fuel tank to the truck. The biggest difficulty with this option is that some of the connections might be very rusty and tough to loosen.

Clear your fuel tank

Before removing your fuel tank, you need to empty it. In order to do this, siphon the gas out using a clear hose and an air pump.

Elevate your truck

Use a standard jack to elevate your truck. Place it in the grooves along the frame of your truck. For trucks that are already lifted, you may have enough room to work without having to jack up your truck.

Remove the heat shield

Once your truck is safely and securely raised, grab your impact wrench and crawl under the truck. You will find that the heat shield is protecting the fuel pump. You will also notice two sets of bolts. One set holds the heat shield in place. The second set holds the fuel tank in place. First, locate and remove the bolts that hold the heat shield. Be careful not to remove the bolts for the tank straps before removing the heat shield. After removing the bolts, the heat shield will start to drop as you remove it. Place your knee against it so it doesn't fall on you as you wiggle it free. Once it is free, put it aside.

Remove the fuel tank

Grab two floor jacks and place them underneath the fuel tank to support it as you remove its bolts. Be sure that the jacks are raised just enough to support the tank. It's a good idea to insert some soft padding between the jack stand and the tank to prevent damage.

Use an impact wrench to remove the four long bolts from the fuel tank. Once both straps are loosened, lower the straps and twist them off. Don't force them or you will wind up ruining the mounting point. Set the two straps and the bolts to the side.

Now your fuel tank should be supported only by the jack stands. Ask somebody to slowly lower the stands while you hold the fuel tank. The front end won't drop right away because it is connected to the fuel fill line. You will need a 1/4 inch hex socket to remove this connection. Once the fuel fill line is disconnected, your assistant can lower the jack stands further and you should be able to pull the fuel tank out from under the truck.

Elevating your truck

To elevate your truck, you will need to use a standard jack. Place the jack in the grooves along the frame of your truck and raise it to a height of at least 18 inches above the ground. If your truck is already lifted, you may not need to jack it up. This step is crucial to ensure you have enough space to work underneath the vehicle safely.

Once the truck is securely raised, grab an impact wrench and crawl under the truck to locate the heat shield, which protects the fuel pump. You will also notice two sets of bolts. One set holds the heat shield in place, while the other set secures the fuel tank. Be careful to only remove the bolts for the heat shield at this stage. After removing these bolts, the heat shield will start to drop, so place your knee against it to prevent it from falling on you as you wiggle it free. Once the heat shield is removed, set it aside.

Now, grab two floor jacks and place them underneath the fuel tank to support it while you remove its bolts. Make sure the jacks are raised just enough to support the tank, and consider using soft padding between the jack stand and the tank to avoid any damage. Use your impact wrench to remove the four long bolts from the fuel tank, and then lower and twist off the straps without forcing them to avoid damaging the mounting point. Set the straps and bolts aside.

With the straps removed, the fuel tank will now be supported only by the jack stands. Slowly lower the stands while holding the fuel tank, as the front end is still connected to the fuel fill line. You will need a 1/4 inch hex socket to disconnect this line. Once the fuel fill line is disconnected, you or your assistant can lower the jack stands further, and you should be able to pull the fuel tank out from under the truck.

Removing the heat shield

To remove the heat shield, you will need an impact wrench. Crawl under the truck and locate the heat shield, which is protecting the fuel pump. You will notice two sets of bolts. One set holds the heat shield in place, and the other set holds the fuel tank in place. Be careful to only remove the bolts for the heat shield, which will be aligned with the heat shield strap. After removing these bolts, the heat shield will start to drop, so place your knee against it to stop it from falling on you as you wiggle it free. Once it is free, put it aside.

The heat shield is attached to the truck with bolts that hold the heat shield strap in place. You will need an impact wrench to remove these bolts. Once the bolts have been removed, the heat shield will start to drop, so it is important to place your knee against it to stop it from falling on you. You can then wiggle it free and put it aside.

When removing the heat shield, it is important to be careful not to remove the bolts for the tank straps before removing the heat shield. This will ensure that the fuel tank remains securely in place while you are working.

The heat shield is located under the truck and can be accessed by crawling under the vehicle. It is in place to protect the fuel pump, which is a critical component of the vehicle's performance.

Removing the old fuel pump assembly

To remove the old fuel pump assembly from your 2000 F150, you have two options: removing the fuel tank or removing the bed. Here's a step-by-step guide for both methods:

Option 1: Removing the Fuel Tank

Step 1: Remove fuel from the tank.

Use a clear hose and an air pump to siphon the gas out of the tank. This step is important for safety reasons.

Step 2: Elevate your truck.

Use a standard jack to lift your truck to a height of at least 18 inches above the ground. Place the jack in the grooves along the frame of your F150. If your truck is already lifted, you may not need to do this step.

Step 3: Remove the heat shield.

Crawl under the truck and locate the heat shield protecting the fuel pump. Use an impact wrench to remove the bolts holding the heat shield in place. Be careful not to remove the bolts for the tank straps. Once the bolts are removed, slowly wiggle the heat shield free and set it aside.

Step 4: Remove the fuel tank.

Place two floor jacks underneath the fuel tank to support it while you remove its bolts. Use an impact wrench to remove the four long bolts from the fuel tank straps. Lower the straps and twist them off gently to avoid damaging the mounting point. Now, slowly lower the jacks while holding the fuel tank. The front end will be connected to the fuel fill line, which you can disconnect using a 1/4 inch hex socket. Once the fuel fill line is disconnected, carefully pull the fuel tank out from under the truck.

Option 2: Removing the Bed

Step 1: Remove the bed.

Use an impact wrench to remove the six bed bolts. You may need the help of two strong friends to lift the bed off the truck. If you don't have help, you can use bed hooks, two ropes, and a chain hoist to lift the bed.

Step 2: Disconnect the fuel filler cap.

Remove the three 7mm bolts holding the filler cap in place and let it hang down.

Step 3: Remove the filler neck clamp.

Crawl under the truck and locate the clamp connecting the filler neck to the bed. Loosen the clamp to free the filler neck.

Step 4: Disconnect the bed and tail lights.

Slide underneath the truck bed and disconnect the wire harness for the bed lighting. You will find it in the left rear corner of the bed. Pull on the two connectors until they come loose. Be careful of falling dirt! Next, remove the two taillight plugs located at each corner of the bed.

Step 5: Lower the bed.

With the help of your friends or using the appropriate tools, lift the bed off the truck and pull the truck forward. Lower the bed onto a soft surface or sawhorses.

Locating and Removing the Old Fuel Pump Assembly

Step 6: Locate and clean the fuel pump module.

Whether you removed the fuel tank or the bed, you will now find the fuel tank behind the cab. Look for the round fuel pump module bolted on top. Before removing the module, disconnect the fuel outlay, relay lines, and evaporative hoses. Use a plastic brush to clean off any dust or dirt from the module and the tank to prevent it from falling into the tank.

Step 7: Remove the old fuel pump assembly.

Use an 8mm wrench to remove the six bolts attaching the fuel pump module to the tank. The module may be stuck to the rubber seal, so carefully use a flathead screwdriver to pry it up if necessary. Lift the assembly out of the tank. The fuel pump module consists of several parts, including the fuel pump, fuel sender, and strainer. If you know which specific part is faulty, you can replace just that part. However, if the pump is old, it is advisable to replace the entire unit with a new one.

Installing the new fuel pump assembly

Now that the old unit is out, you can install the new one. Drop the new fuel pump assembly into the fuel tank, aligning it with the mark you made earlier with your Sharpie. Replace the screws and tighten them. Reconnect the outlay and relay lines, as well as the evaporative hoses.

If you removed the bed, you will need to reinstall it and reconnect the lights, gas fuel filler cap, and neck clamp. If you removed the fuel tank, put it back in and reconnect all the straps and bolts. Don't forget to reattach the fuel fill line.

Now, you have successfully installed a new fuel pump.
