In the world of diesel engines, the 7.3-liter Power Stroke is an iconic workhorse known for its reliability and performance. To keep this powerhouse running at its best, regular maintenance is key. One essential task every Powerstroke owner should be familiar with is changing the fuel filter. In this comprehensive guide, we will walk you through the process of how to change the fuel filter on a 7.3 powerstroke step by step, ensuring your engine gets the clean fuel it deserves.
Where is the Fuel Filter Located?
One of the primary reasons for avoiding the 7.3L Powerstroke diesel engines produced between 2001 and 2014 is the issue of fuel filter housing leaks. This concern is particularly relevant due to the design of the 7.3L Powerstroke engine, where the fuel filter is typically situated near the front of the engine within the valley. This placement is consistent across various models of the 7.3L Power Stroke engine and often includes a drain valve and tube system. These features enhance the convenience and efficiency of routine maintenance, allowing for the easy removal of water and sediment from the housing without the need for complete disassembly
How To Change The Fuel Filter in a 7.3 Powerstroke
Tools and Parts Needed:
Before you begin, gather the necessary tools and parts for the job. Here’s what you’ll need:
- New fuel filter
- O-ring
- Cap gasket
- Rags
- Drain bucket
- Oil filter wrench or pliers
- Brass drift with a blunt tip (optional)
Step 1: Preparing the New Fuel Filter
Start by unpacking your new fuel filter. Slide the provided O-ring onto the filter. Ensure that the O-ring is fully seated, creating a secure seal.
Step 2: Locating the Old Fuel Filter
The fuel filter on the 7.3-liter Power Stroke engine is conveniently located in the center of the engine valley. This central position makes it easily accessible for replacement.
Step 3: Protecting the Work Area
To minimize mess, wrap rags around the fuel filter, especially near the cap area. Keep in mind that the fuel spillage you’ll encounter during this process is simply overflow from the bowl and not pressurized. Place a drain bucket nearby to catch any fuel that may spill during the filter replacement.
Step 4: Fuel Draining Procedure
4.1. Locating the Fuel Filter Housing Drain Tube:
Based on your engine model the drain tube can either run vertically along the front of the passenger side or be situated along the side of the engine.
4.2. Connecting a Drainage Hose:
Once identifying the tube, attach a piece of fuel line into it measuring 7.95mm or 8mm in diameter, with a length of approximately 25 to 33 inches. Make sure the hose reaches down to the floor, and place a pot to collect the drained fuel.
4.3. Initiating the Fuel Draining Process:
Next, you will find a yellow-colored lever often called as drain valve which you need to rotate clockwise direction by 90 degrees. You will find that lever or the drain valve on the backside of the round fuel filter housing, and there’s a metal tube that comes out beneath the filter housing. Keep a close watch on the container’s or pot’s level, as you will be draining approximately 2 to 3 pints of fuel.
Step 5: Removing the Old Fuel Filter
With the old filter removed, take a moment to inspect the fuel bowl. Look for any excessive debris or contaminants that may have accumulated over time. Pay close attention to the fuel heater element. Ensure it’s not corroded or rusty, as a damaged heater can lead to electrical issues down the line.
Step 6: Removing the Old Seal
The old cap gasket seal can often be stuck in place. Carefully remove it and discard it. If it’s stubborn, a gentle yank may be necessary.
Step 7: Installing the New Fuel Filter
Now, it’s time to install the new fuel filter. Place the new filter into the housing, ensuring it’s seated properly. Before inserting the new seal, make sure to clean the rim of the housing. The seal should be positioned with a flat bottom and angled inward when installed. This may seem unusual, but it’s the correct orientation.
Step 8: Reattaching the Cap
Carefully screw the cap back onto the housing. Be cautious not to overtighten it; simply ensure it’s snug and secure. There’s no need for excessive force.
Step 9: Checking for Leaks
Clean the area surrounding the filter thoroughly. Next, cycle the key a couple of times before starting the engine. This step helps you detect any potential leaks before the engine is running. Once the engine is running, closely monitor for leaks as it idles.
When To Change Fuel Filter In Your 7.3 Powerstroke
1. Regular Maintenance Intervals:
Replacing the fuel filter on your 7.3 Power Stroke should be a part of your regular maintenance routine. Most experts recommend changing the fuel filter every 15,000 to 20,000 miles. This interval can vary slightly depending on driving conditions, fuel quality, and the specific year of your engine.
2. Fuel Quality and Contaminants:
If you frequently fill up at gas stations with questionable fuel quality or have reason to suspect that your fuel source may contain contaminants, you should consider replacing the fuel filter more often. Low-quality or contaminated fuel can lead to a quicker buildup of debris in the filter, reducing its efficiency.
3. Loss of Engine Power:
A noticeable loss of engine power or a decrease in fuel efficiency can be an indicator that your fuel filter is clogged or nearing the end of its lifespan. If you experience these symptoms, it’s advisable to inspect and replace the fuel filter promptly.
4. Rough Engine Performance:
A rough-running engine, including symptoms like misfires, stalling, or hesitation during acceleration, can be caused by a restricted fuel flow due to a clogged fuel filter. In such cases, replacing the filter can often resolve these issues.
5. Difficulty Starting the Engine:
If you find that your 7.3 Power Stroke engine is becoming increasingly difficult to start, especially in cold weather, a clogged or partially blocked fuel filter may be the culprit. Replacing the filter can improve starting performance.
6. Warning Lights or Error Codes:
Modern vehicles, including those equipped with 7.3 Power Stroke engines, often have onboard diagnostic systems that can trigger warning lights or error codes related to fuel system issues. If you receive such warnings, it’s essential to have the system diagnosed promptly, and replacing the fuel filter may be part of the solution.
7. Follow Manufacturer Recommendations:
Always consult your vehicle’s owner’s manual for manufacturer-specific recommendations regarding fuel filter replacement intervals. Manufacturer guidelines can vary, so it’s crucial to follow the specifications provided for your particular model year.
How Much It Would Cost To Replace Fuel Filter Of 7.3l
A basic fuel filter for a 7.3-liter diesel engine might cost anywhere from $10 to $30, depending on the brand and quality of the filter. Labor costs for installation can vary significantly, but it’s generally advisable to get a quote from a local mechanic or repair shop for the most accurate estimate. Labor costs could range from $50 to $150 or more, depending on where you live and the shop’s pricing.
