How to Change Fuel Filter on 6.7 Cummins

Although 6.7 Cummins engines are known for being reliable, improper maintenance could still result in head gasket issues and fuel filter replacement is one way you can help ensure optimal performance from your truck. To stay ahead of potential issues and keep it in prime condition, invest in new filters today.

Step one of installing a fuel filter involves draining its contents. Each filter housing contains a nipple with an integrated water drain valve; connect a hose directly to this nipple and drain all fuel directly into a catch pan.

Removing the old filter

Switching out your fuel filter regularly on your 6.7 Cummins is an inexpensive and straightforward preventative maintenance procedure, that can help guard against fuel injector problems or engine failure. Fuel filters remove impurities that damage injection pumps or common rail, keeping your system cleaner than before.

To change a fuel filter on a 6.7 Cummins truck, a cylindrical canister must be located beneath it near the firewall, with fuel lines attached. In order to do so safely and without spillage of any sort, safety glasses and gloves must be worn and an overflow pan placed beneath to catch any droplets of fluid that might leak during this process.

Step one in changing a filter involves draining all fuel through the water drain valve on the bottom of the housing and replacing both filter and O-rings, including any necessary silicone grease to reduce wear and tear and increase flow rates. As part of step two, lower housing before installing new filter. During these processes lubricate O-rings with fuel injector oil or silicone grease for optimal results – it will reduce wear-and-tear and improve fuel delivery rates.

Draining the fuel

Fuel filters remove impurities from diesel fuel, prolonging engine lifespan and performance while helping meet emission standards, contributing to cleaner exhaust emissions. They should be considered an integral component of your 6.7 Cummins’s fuel system and should be regularly replaced for maximum effectiveness.

To empty your 6.7 Cummins fuel filter, loosen and disconnect the two quickdisconnect fuel lines attached to it. After these have been disconnected from the filter, open its drain valve and drain away any leftover fuel through its drain hole. Use only quality filters when draining.

Air in your 6.7 Cummins’ fuel can create serious problems. It can cause metal-onmetal contact in the injection system and lead to injector damage, leading to soot production, loss of power and potentially thousands of dollars worth of repairs or replacement components. Air can easily be prevented with installation of a FASS Fuel Filtration System; our systems filter up to 2 Micron debris so only pure diesel enters your injection system.

Removing the filter housing

Filter housings on 6.7 Cummins engines are cylindrical canisters which house both fuel filters and lines. Held together with 14 plastic snap fasteners, it can be removed easily in just minutes.

Change your fuel filter regularly before it becomes clogged and causes issues with your engine, and also prime it after installing a new one; this can be accomplished by cycling off and on your key several times without starting the engine.

The 6.7 Cummins fuel filter can be found on the driver side of your vehicle and should be changed every 15,000 miles or every year to keep impurities out and ensure diesel meets emission standards. It should also provide protection from engine-damaging injection pumps.

Installing the new filter

Install the new filter by tightening its bolts or nuts, being mindful to wear safety glasses and gloves during this process to avoid fuel spillage, and having a drain pan handy to capture any potential leaks that may occur.

The 6.7L Cummins fuel filter can be found on the driver’s side of your engine compartment and is housed within its cylindrical canister with fuel lines attached. Additionally, this part includes a water-in-fuel sensor – making its replacement an essential task to maintaining engine performance. Changing it on this truck may prove tricky but is essential to its optimal running.

With just a few tools and some patience, you can change the fuel filter on your Dodge Ram 2500/3500 truck in under 5 minutes. This simple maintenance procedure should be performed regularly to help avoid expensive tow bills; just remember to cycle the key several times after removing the old filter to ensure all air has been removed from your system.
