Replacing Fuel Pump In '21: Diy Guide For Your Car

Changing a fuel pump can be a challenging task, but with the right tools and precautions, it can be done safely and effectively. A fuel pump is an essential component of a car's fuel system, transferring fuel from the tank to the engine, where it is aerosolized and combusted to power the vehicle. While fuel pumps are durable, they may eventually need to be replaced due to wear and tear, contamination, or electrical faults. Before attempting to replace a fuel pump, it is crucial to consult a vehicle-specific repair manual and ensure you have the necessary tools and safety equipment. The process typically involves relieving the fuel system pressure, accessing the fuel tank, disconnecting the old pump, and installing a new one, but it can vary depending on the vehicle model.

Drain the fuel tank

To drain the fuel tank of a 201, you will need to place a large pan under the drainage plug, or the small bolt screwed directly into the gas tank. Make sure you have the appropriate containers to catch the fuel.

The drainage plug is usually located near the bottom of the fuel tank, on the same side of the car as the gas tank filler. It is often found underneath the passenger-side seat.

Once you have located the drainage plug, use a spanner or socket wrench to remove it. The fuel will then begin to drain into the pan. This process can take several minutes per gallon, so be sure to keep an eye on it to prevent any spillages.

If your car does not have a drainage plug, you can use the fuel lines to drain the tank. To do this, turn the car on and off repeatedly to force the fuel out of the tank, using the electric fuel pump.

Once the tank is empty, replace the drainage plug and refill your car with gas.

Disconnect the battery

Disconnecting the battery is an important step when changing the fuel pump on your 201. It is a safety precaution to prevent any accidental sparks that could cause an explosion, as you will be working with flammable liquid.

To disconnect the battery, locate the negative terminal, which will be marked with a minus (-) sign. You may need to remove a plastic cover to access the terminal. Once located, use a wrench or socket to loosen the nut that secures the cable to the terminal. Be careful not to touch any metal parts of the wrench or socket with the battery terminal, as this could cause a spark.

After the nut is loosened, carefully remove the cable from the terminal. Ensure that the cable does not touch any metal parts of the car, including the battery terminal, as this could also cause a spark. You may want to cover the disconnected terminal with tape or a plastic bag as an extra precaution.

Now that the battery is disconnected, you can proceed with the rest of the fuel pump replacement process, which includes relieving the fuel system pressure, removing the fuel tank, and disconnecting and reconnecting various components. Remember to reconnect the battery once you have finished the replacement process and before starting your car.

Remove seats and clutter from the trunk

To remove the seats and clutter from the trunk of your car, follow these steps:

Firstly, locate the rear seats of your car that need to be removed. This will give you access to the trunk and the fuel tank. You may need to fold down the rear seats or remove them completely, depending on the car model. If the seats need to be removed, you can refer to a car manual or a YouTube tutorial for the specific make and model of your car.

Next, clear out any clutter or unnecessary items from the trunk. Take everything out and divide the items into categories: trunk essentials, items that belong in your home or garage, and items to throw away or donate. Some essential items to keep in your trunk include a portable air compressor, a trash bag or small trash can, and an emergency kit. The emergency kit can include items such as a portable phone charger, water, and non-perishable food.

To maximise space, utilise vertical storage solutions such as velcro strips or hooks to secure small, loose items like umbrellas or flashlights. This will also prevent items from moving around while driving.

Additionally, consider using organisers or clear storage bins to keep similar items together. This makes it easier to locate specific items and maintain a neat appearance. Label the bins with their contents, so you always know what's inside.

Finally, remember to schedule regular deep cleaning sessions for your trunk. Remove all items, vacuum, and address any stains. This is also an opportunity to reassess the items you keep in your trunk and rotate seasonal items.

Disconnect fuel lines and clips

Disconnecting the fuel lines and clips is a challenging task during a fuel pump replacement. There are various types of fuel line styles, and the process for disconnecting them differs for each. Here is a step-by-step guide on how to disconnect the fuel lines and clips for a 201x model vehicle:

First, locate the fuel lines and clips. These are usually found near the fuel pump, which is typically located inside the fuel tank. Next, identify the type of connector used on your fuel lines. Common types include push-type, push-and-lock, pinch-type, spring-style retainer, hose and clamp style, and horseshoe-type connectors.

For push-type connectors, you may need to push from both directions to release it. If it's a one-sided connector, simply push it down and pull it off. Push-and-lock connectors require you to push the locking tab through and then release the safety latch to disconnect. Pinch-type connectors have retainers on each side that you need to pinch together to disconnect.

Spring-style retainer fittings have a black ring that serves as a release tool. Pull the ring back toward the fitting and then remove the fitting. If you have a hose and clamp-style fitting, use pliers to pinch the clamp together, slide it back, and pull the line off.

Horseshoe-type fittings have a clip that holds them in place. Use a screwdriver to carefully pry the horseshoe clip up and out of the fitting. Finally, when disconnecting the fuel lines, be cautious not to break them. If any part of the line breaks and remains in the fitting, use a release tool and insert a screw or bolt that fits to pull out the fitting.

Remember to take your time and be cautious when working with fuel lines, as they contain flammable liquids. Always refer to your vehicle's service manual or online tutorials for specific instructions and safety precautions.

Reassemble the fuel system

Reassembling the fuel system is the final step in changing a fuel pump. Here is a detailed, step-by-step guide on how to do this:

Firstly, reconnect the fuel lines and quick clips. You may want to replace the quick clamps with hose clamps at this stage. Ensure you remember which fuel line goes where. Next, put the foam gasket and access panel back on. Then, put the styrofoam cubby back in, followed by the seats.

After this, reconnect the green clip under the dashboard, and reconnect the battery. Tighten the gas cap. Finally, start the car and check that it works.

Some additional notes: you may want to do steps 20-23 from the previous guide before step 17, so that if there is an issue, you can quickly access everything. It may also be best to do this with an almost empty gas tank. Wear a respirator or breathing apparatus to avoid inhaling harmful fumes. Take the time to vacuum up all the crud and collect spare change from under the seats.
