Flatbed driving can be one of the more difficult aspects of trucking. But with the Peterbilt 579 making this task seem effortless and providing a delightful driving experience both on and off-highway, this task becomes one you’ll look forward to every time.

The new Model 579 delivers up to 7% fuel savings compared to similar spec vehicles through its EPIQ package, and features a discreet sleeper to allow it to be reconfigured into another application at resale time.

How to Change the Fuel Filter

Procedures for installing or changing a Peterbilt 579 diesel truck’s fuel filter vary slightly depending on its manufacturer and engine manufacturer; for more specific instructions please refer to your owner’s manual. However, here are some general guidelines that can help make this task successful: Drain out old filter by loosening its drain plug (usually using an allen or hex wrench), once all fuel has drained from it you can take steps such as taking off cap to allow excess fluid out before pulling out dirty filter, installing new one and tightening by hand until manufacturer specifications require tightening (usually using torque wrench).

1.       Remove the Fuel Filter

While some aspects of changing out a fuel filter may vary from vehicle to vehicle, all truckers should take certain general steps when changing it out. It is crucial that any air bubbles be cleared from the system and that diesel is primed before use to prevent “vapor lock.”

Next, it is necessary to drain the dirty fuel filter by unplugging its drain plug with a hex tool or socket and taking steps to dislodge it from its housing. After doing this, remove and install a clean one into its place while also cleaning its cap and seal surface on its housing.

2.       Unscrew the Fuel Filter Cap

Peterbilt’s 2023 Model 579 truck represents their relentless focus on increasing uptime, fuel efficiency and driver comfort to new levels. Its sleek design and innovative features make it the most efficient Class 8 truck on the market today.

On the exterior, the Model 579 appears narrower and its hood lower than previous models. Its stainless steel grille is both stylish and long-term durable while its fenders boast “valleys” near its body which help reduce drag.

The 579 is equipped with an exceptionally comfortable sleeper area that features a 42-inch wardrobe, 22-inch flatscreen TV, workstation and SmartLINQ technology for automated tracking of engine and emission parameters.

3.       Remove the Filter

Your truck may require you to loosen a drain plug before you can gain access to its filter. Use either a hex tool or allen wrench to loosen it and allow fuel to drain into a pan, after which time you can remove its dirty filter and install a new cap with new O-rings that help prevent leaks.

Once the filter cap and housing have been cleaned, install your new filter using a torque wrench, following manufacturer specifications to tighten its cap securely.

4.       Clean the Filter Cap

Once the old filter has been removed, it is imperative that the cap and sealing surface of its housing be thoroughly cleaned. Use a pry tool or flathead screwdriver to take this step; use an O-ring removal tool on both caps to unfasten their O-ring before cleaning both parts with soapy water before installing a new O-ring from your new filter – one of the main causes of diesel fuel cap leaks can be improperly installed O-rings.

Once the new filter has been installed, carefully tighten its cap by hand or use a

torque wrench to ensure that it conforms to manufacturer specifications.

5.       Install the New Filter

Fuel filters remove dirt and debris from fuel before it enters your engine, helping protect against potential issues with injectors or gum up other parts. Regular replacement will ensure optimal performance while also protecting against potential damages to parts.

Once installed, reconnect any lines that had become disconnected during installation of the new fuel filter and apply thread sealant where needed. Also be sure that your filter cap fits securely; use a torque wrench if necessary for this step.

Before installing the O-ring on the filter cap and sealing surface on the housing, it’s advisable to wipe down both. Finally, place it against the ridge around the cap so it sits flush against it.

6.       Tighten the Filter Cap

Filter caps should fit securely and should snap into place easily, using a wrench to tighten them to manufacturer specifications – over or under tightening can result in leaks.

Verify the rubber fuel filter gasket to ensure it has not been cut, nicked, or twisted and is still fitting securely into its baseplate. If any damage occurs to this piece of rubber, replace it immediately.

Once you’re finished, reinstall the drain plug and bleed any air bubbles to prime your diesel fuel system before filling your tank and driving safely! Looking for more trucking tips? Read up here.
