Tools Required

• 36mm socket
• 6mm Allen wrench
• 24mm socket or 1/2" drive ratchet
• Strap wrench or large Channellock pliers
• 13mm socket and ratchet

Step-by-Step Guide

Step 1: Drain the fuel

Place a tub or bucket beneath the fuel pump, which is located under the driver's door on the frame rail. Locate the allen plug on the side of the fuel pump. Using the 6mm Allen wrench, remove the allen plug and drain the fuel/water completely.

Step 2: Remove the primary fuel filter cap

Using a 36mm socket, remove the primary fuel filter cap along with the O-ring. Install the new primary fuel filter into the cap and the supplied O-ring into position on the end cap. Insert the new filter and cap section into the fuel pump, using the 36mm socket to tighten the cap securely. Reinstall the allen plug.

Step 3: Remove the secondary fuel filter cap

Using a 24mm socket or 1/2" square drive ratchet, remove the black top cap of the secondary fuel filter, located in the engine compartment. Remove the fuel filter from the housing and the O-ring from the lid. Using a turkey baster, drain the excess fuel from the housing.

Step 4: Install the new secondary fuel filter

Insert the new secondary filter into the housing and install the new O-ring onto the lid. Reinstall the black top cap, using the 24mm socket or 1/2" square drive ratchet to torque the bolt.

Step 5: Prime the fuel system

Before starting the engine, turn the ignition to the "Run" position three separate times for 30 seconds each time. This will prime the fuel system and bleed out any air.

Tips

• It is recommended to replace the fuel filter every 10,000-15,000 miles for the health of the fuel system.
• It is not mandatory to drain the fuel bowl to replace the filter, but it is a good opportunity to remove any accumulated water.
• Coat the O-rings with diesel fuel before placing them in the groove of the fuel filter.
• After draining the filter for 24 hours, you can place it in a lidded coffee can or leak-proof plastic bag for safe disposal.
• It is a good idea to cycle the key without starting the truck to energize the fuel pump and check for leaks.

Common Issues

• Some people have found that the upper secondary fuel filter does not have a clamp to hold it in place.
• It can be difficult to get the secondary fuel filter out of its housing. Applying grease to the outside of the new filter may help with future extractions.
• Be careful not to over-tighten or cross-thread the allen plug.
• Failing to properly prime the fuel system can cause serious damage to the injectors.

Average cost of a fuel filter replacement

The average cost for a fuel filter replacement is between $70 to $221, including parts and labor. The parts alone can cost between $45 and $106, while labor costs can be anywhere from $91 to $114.

The cost of a fuel filter replacement varies depending on the type of filter and the cost of labor. For instance, a fuel filter kit for a Ford F250, F350, F450, F550, or F600 Super Duty Pickup can be purchased for $87.79, while the Motorcraft FD4624, which includes filters for both the fuel filter and the fuel/water separator, is available for $58.

It is important to note that the fuel filter is an essential component of a vehicle's fuel system, helping to remove contaminants and impurities such as rust and dirt. A clogged fuel filter can cause problems with starting the car, stalling, excessive vibration while driving, and rough slow-speed cruising. Therefore, it is recommended to change the fuel filter periodically as part of routine maintenance.

Symptoms of a bad fuel filter

The cost of changing a fuel filter for a diesel F350 varies depending on where you get it done. A Ford dealership may charge around $250, while online retailers sell fuel filter kits for as low as $44.95. You can also find the fuel filter on Amazon for $58. If you're looking to save some money, you can buy the fuel filter separately, not as part of a kit.

Now, onto the symptoms of a bad fuel filter:

Hard Starting

Difficulty in starting your engine could be one of the initial signs of a malfunctioning fuel filter. As the fuel flow is restricted due to clogging, it may require excessive cranking to start the engine. While there might be other reasons for this issue, checking the fuel filter is a good place to start troubleshooting.

Engine Hesitation

A clogged fuel filter can cause the engine to hesitate or stumble under various conditions, such as starting from a stop, accelerating, or driving uphill. The insufficient fuel flow through the obstructed filter results in a "bucking" sensation, which can be dangerous when making quick driving decisions.

Misfires and Decreased Power

A partially clogged filter allows varying amounts of fuel to pass through, leading to misfires and reduced engine power. This issue may come and go as you drive, and you may also notice jerking or stuttering sounds from the engine.

Check Engine Light Comes On

Although the fuel filter is not directly linked to the engine computer, a blocked filter can trigger various trouble codes, including a lean running condition and a mass airflow sensor fault. Getting a proper diagnosis is crucial before replacing any expensive parts of your emissions control system.

Stalling

A clogged fuel filter may allow just enough fuel to start the engine but not sufficient for acceleration and cruising. As a result, the engine may stall when you start driving and then restart, only to stall again when you accelerate or drive at higher speeds.

Engine Won't Start

If the fuel filter is completely clogged, no fuel will be able to pass through, rendering the engine unable to start. No matter how much you crank the starter, the engine won't catch, and your vehicle will remain inoperable until the faulty fuel filter is addressed.

Power Varies at Different Speeds

In some cases, a vehicle with a dirty fuel filter may perform adequately at higher speeds but experience driveability issues at lower speeds. The higher fuel pressures generated during high-speed operation can overcome the obstruction in the filter. However, when you slow down, the smooth operation is lost, and you may experience symptoms such as engine hesitation or stalling.

Rough Engine Idle

A faulty fuel filter can cause the engine to idle roughly, with stuttering or vibration as it struggles to get enough fuel. The tachometer may also indicate erratic needle movement at the low end of the range.

It is important to note that while a clogged fuel filter can cause these issues, there might be other underlying problems as well. Therefore, it is always recommended to consult a professional mechanic for an accurate diagnosis and repair.

Safety of driving with a fuel filter problem

The safety risks of driving with a fuel filter problem are significant and should not be ignored. Here are some reasons why:

Engine Performance and Damage

A clogged or faulty fuel filter can lead to a series of issues with your engine's performance, including inconsistent power, poor acceleration, and engine misfires or stalling. The engine might sputter or hesitate, especially at high speeds, and you may experience a lack of power. These problems can make it unsafe to drive, especially when overtaking or merging. In addition, driving with a compromised fuel filter can cause the engine to work harder, leading to reduced fuel efficiency and potential engine damage over time.

Fuel Contamination

The primary job of the fuel filter is to filter out impurities from the fuel before it reaches the engine. A non-functioning or faulty fuel filter means these impurities can reach the engine, compromising the quality of combustion and leading to impure exhaust fumes. This can also cause a decline in the overall health of the engine.

Safety Concerns

Driving with a compromised fuel system can pose direct safety risks. From unexpected stalling on highways to decreased responsiveness during overtaking, the dangers are very real. A bad fuel filter can lead to unpredictable vehicle behavior, which can put you, your loved ones, and other road users at risk.

Fuel Pump Issues

A clogged or faulty fuel filter can cause your fuel pump to work harder, leading to unusual noises and potential failure. The fuel pump will try to compensate for the restricted fuel flow, placing undue pressure on the pump motor, which can lead to premature fuel pump failure.

Environmental Concerns

Without a functional fuel filter, the chances of unburnt fuel increase, leading to more harmful emissions in the exhaust. This is not just an environmental concern but could also be a reason for failing emission tests in regions where they are mandatory.

Cost Implications

While the average cost of a fuel filter replacement, including labor, can range from $50 to $150, waiting too long and letting a bad filter damage other parts of the vehicle will be much more expensive. A failing fuel filter can cause severe engine problems and reduced vehicle performance, leading to costly repairs.

In conclusion, while it is technically possible to drive with a bad fuel filter, it is not advisable due to the safety, performance, environmental, and cost implications. It is important to prioritize the immediate replacement of a faulty fuel filter to ensure optimal vehicle performance and your safety on the road.
