Tips And Tricks For A Quick and Piece of cake Filter Change - Fuel Filter Basics

Don't let this happen to yous!

Clean fuel is key to a healthy diesel engine. Fuel filter replacement is one of the major maintenance items that is often neglected or overlooked entirely. Diesel fuel fuel filters also serve a dual purpose, filtering out both debris and h2o. When filters get chock-full, they tin permit water to bypass them, contaminating the truck'due south injection system. Waiting until the filter element is completely plugged before changing can too lead to fuel starvation that will non just cause functioning loss, but also potentially damage injectors, injection pumps, and lift pumps. The bottom line is: Bad things happen when filters are left unchanged.

The adept news is, however, changing a fuel filter is something everyone tin exercise. All that's needed are the new filter (or filters if you own an '03 or newer Ford), a catch pan or bucket, and a couple of basic handtools. This calendar month'due south basic grooming lesson is non meant to exist an spread-out guide to changing your specific filter, rather a primer demonstrating the ease and basic procedure for near trucks. Exist sure to consult your owner's manual for your truck'southward specific filter change intervals (typically around 15,000 miles) and filter office numbers. Diesel fuel filters aren't always cheap, just nosotros propose purchasing factory replacement units, as some of the more cheap alternatives don't always provide the protection sensitive high-force per unit area fuel systems require.

After you've read this and decided information technology's fourth dimension to change your fuel filter, a slap-up resource for footstep-by-stride instructions for the offset- timer is the Cyberspace. While it may seem obvious to some, make-specific forums, Google, and YouTube are chock-total of how-to stories and instructional videos. With their help at that place is no reason to shy away from performing a filter modify at home, saving a costly trip to the dealer and keeping your fuel organisation in tip-elevation shape.

Both 5.9L and half-dozen.7L Cummins fuel filters are located on the driver side of the engine, below the intake manifold.

Cummins

On Cummins engines, the fuel filter type and way has changed slightly over the years, so for our purposes nosotros're going to draw those found on the common-rails engines. Both 5.9L and 6.7L filters are located on the driver side of the engine, below the intake manifold. The major departure lies in how they are oriented, with the 5.9L filter beingness accessible from the topside of the engine and the 6.7L from nether the truck.

To change the filter, the first footstep is draining the fuel. Located on the bottom of the filter housing is a h2o drain valve. Attach a hose to this nipple and route it to a catch pan, and so open the valve and bleed the fuel. With the filter drained y'all tin now remove the housing. On the 5.9L, the cap is removed and the filter lifts upward and out, however, on the 6.7L you lot first need to unplug the water-in-fuel sensor before lowering the canister and filter out through the bottom of the vehicle. The filters are reinstalled in the reverse order; make sure to replace and lubricate the canister O-ring. To prime the system, bike the key without starting the truck 10 to 20 times.

All the Cummins-equipped Rams utilize a cartridge-way filter, with the five.9L being accessible from the elevation. A 1 1⁄8-inch socket is used to remove the filter cap.

The Duramax fuel filter is located on the passenger side of the engine compartment, nearly the firewall and side by side to the bombardment. Due to its location, guys with larger hands need to think skinny in order to get a grip on the filter. Removing the plastic fenderwell liner is the easiest way to expose the filter, since it is but held on with almost xiv plastic snap fasteners and takes mere minutes to remove. Making the Duramax fuel filter unique is its integrated water-in-fuel sensor, which besides houses the water drain petcock. This sensor needs to be unplugged from the vehicle'south wire harness before spinning the filter off, and once removed, a special wrench is required to remove and install the sensor.

Replacement filters will provide two new O-ring seals: one for the sensor bulkhead and one for the filter'south sealing surface, both of which should exist lubricated with a petroleum-based lubricant before being installed. Once the new filter is fastened to the truck, it's time to prime number the filter. On the Duramax, priming is done by first opening the relief valve (achieved with a ½-inch nut driver or flat-head screwdriver) and then manually depressing the primer pump located on top of the filter housing. This process takes a bit of time, then patience is key. Once all the air is bled from the filter, the relief valve should be closed and the process is complete.

This is the Duramax fuel filter's manufacturing plant location. Every bit you can come across, it tin be tough to accomplish from the tiptop.

While some people resort to pliers to remove the fuel-in-water sensor, there'due south a special tool that makes the job much easier and doesn't take chances destroying the delicate plastic.

On this relocated filter you can clearly meet the relief valve and the primer pump.

The Power Stroke family unit of engines is the most unique when it comes to not only fuel filter type and placement, but also quantity. While the Duramax utilizes a single sealed spin-on-blazon filter and Cummins uses a single cartridge, Fords equipped with 6.0L, 6.4L, and 6.7L engines receive 2 cartridge filters (7.3L engines use a single cartridge.) The primary filter is located along the driver framerail at about the midpoint of the chassis, and brake lines and wire harnesses can obstruct depending on year. On '03 and newer models, the secondary filter is located on top of the engine.

Thankfully, changing the filters is a relatively straightforward task. The first step is to drain the filter using the water drain valve. While the procedure is the same, the actual drain valve is different on each engine model. With the fuel tuckered, the canister cap can exist removed and the new filter installed. Brand certain to supersede the old O-rings with the ones provided. On the vi.0L and 6.4L engines, the secondary filter is changed in much the same way. Simply remove the plastic cap and replace the filter element and O-ring.

As a departure from the previous cartridge-mode secondary filter, the 6.7L uses a sealed cartridge, which is replaced as a unit. Replacement requires a setscrew to be loosened and the 2 quick-disconnect fuel lines to be removed. With those steps complete, the unit only lifts out for disposal. For a quick way to know if the filter has e'er been changed, look for a tertiary nipple, which is present only on the original manufactory filter.

Priming the fuel arrangement simply requires the key to be cycled 10 to 20 times without starting the engine. This will allow the vehicle's low-force per unit area fuel pump to fill the new filters with fuel and purge the system of air.

If you're lucky plenty to own a half dozen.0L, 6.4L, or 6.7L Power Stroke, you'll find a secondary fuel filter, similar to this one, under the hood.

Seen here is the primary fuel filter on a 6.0L-equipped F-550 four-wheel drive. Mounted near mid-chassis on the driver side, this truck's filter is partially obscured by the front driveshaft. Likewise notation the water drain is a plug, which is removable with a hex bit.

On 6.4L-equipped trucks, the water drain valve became more user friendly—and information technology got even easier on vi.7Ls.
