Where is the fuel filter located on a 2018 Dodge Journey?

The fuel filter on a 2018 Dodge Journey is not a separate serviceable unit you replace under the hood. It is integrated with the fuel pump module inside the fuel tank, and access for replacement generally requires dropping the fuel tank or accessing a pump assembly via an internal rear-area panel.

In context, this means there isn’t an easily replaceable inline filter mounted in the engine bay. If the filter needs replacing, it is typically done by replacing the fuel pump module, which can involve tank work and professional service.

How fuel filtering works on this model

Chrysler’s design for newer vehicles commonly places the fuel filter inside the fuel pump assembly within the tank. This setup reduces maintenance items you can replace outside the tank and concentrates fuel filtration at the pump module. For the 2018 Journey, there is no traditional external fuel filter you would change like in older trucks or cars.

Location specifics

Here are the key facts about where the fuel filter is located and how it is serviced on the 2018 Dodge Journey.

There is no separate, serviceable inline fuel filter under the hood; the filter is part of the fuel pump module inside the fuel tank.

Access to the pump module is not via a simple hood panel; it requires accessing the fuel tank area, which may involve removing a cover or lowering the tank in many cases.

Replacing the filter typically means replacing the entire fuel pump module rather than swapping a standalone filter, and it usually requires professional service.

These points emphasize that routine DIY filter maintenance isn’t part of the Journeys’ service routine; if fuel issues are suspected, a trained technician should diagnose fuel delivery or filtration concerns.

Access and service considerations

Because the filter lives inside the fuel tank as part of the pump assembly, working on it involves tank access, fuel-system safety protocols, and proper handling of fuel lines and electrical connectors. If you’re experiencing symptoms such as poor fuel pressure, rough idling, or decreased performance, consult a dealer or qualified mechanic rather than attempting tank-level work yourself.

What to do if you’re diagnosing fuel issues

Start with non-invasive checks before considering pump-module replacement. Check for obvious signs like fuel smells, leaks, or trouble codes related to the fuel system. Ensure the vehicle is in a safe location, the battery is disconnected when necessary, and you follow all safety procedures for fuel systems. For most owners, professional diagnostics are recommended to confirm whether the issue is with the pump module or other components of the fuel system.

Summary

For a 2018 Dodge Journey, there isn’t a separate, user-serviceable fuel filter under the hood. The filtration element is integrated into the fuel pump assembly inside the fuel tank, and access typically requires tank work or specialist service. If filtration or fuel delivery issues arise, plan for professional diagnostics and, if needed, replacement of the entire pump module rather than a standalone filter.

Where is the fuel filter located?

The fuel filter is typically located along the fuel line underneath the vehicle, often near the fuel tank or along the frame rail. However, in some modern vehicles, it is integrated inside the fuel tank and is not a separate, serviceable part. To find the exact location, it is best to consult your vehicle's owner's manual.

Common locations

Underneath the vehicle: Look for a cylindrical canister along the main fuel line that runs from the fuel tank to the engine.
Along the frame rail: This is a common location, often on the driver's side of the vehicle.
Inside the fuel tank: Some newer cars have a fuel filter that is part of the fuel pump assembly inside the gas tank. This is often a non-serviceable part, meaning it is replaced only when the fuel pump is changed.
Under the hood: In some cases, the fuel filter may be located in the engine compartment within the fuel line.

Tips for finding your fuel filter

Check your owner's manual: This is the most reliable way to find the exact location for your specific make and model.
Trace the fuel line: Follow the metal or rubber fuel line that runs from the fuel tank toward the engine. The filter will be inline somewhere along this path.
Look for a canister: The filter is often housed in a small, metal or plastic canister with fuel lines connected to both the inlet and outlet sides.

Where is the fuel filter located in a 2018 Dodge Journey?

The fuel filter is positioned in the line leading from the gas tank to the engine and prevents containments from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining.

What is the most common problem with Dodge Journeys?

The most common problems with the Dodge Journey include electrical system failures (especially with the keyless entry and remote start), engine overheating due to coolant issues, and premature brake wear. Other frequent complaints involve water leaks, particularly in the interior, and transmission problems like slipping or hard shifting, particularly in certain model years.

This video discusses common Dodge Journey problems, including electrical, engine, and transmission issues: 52sOBD InsightsYouTube · Aug 2, 2024
Electrical problems

Remote keyless entry: Intermittent or complete failure of the keyless entry system is a frequently reported nuisance.
General electrical issues: Owners report problems with the Totally Integrated Power Module (TIPM), dead batteries, and malfunctioning power accessories.
Airbag malfunctions: This can include spontaneous deployment or failures, often indicated by a flashing airbag light.

Engine and cooling system issues

Overheating: Particularly in models from 2009-2016, the engine can overheat due to a clogged coolant port in the thermostat housing.
Oil consumption: The 2.4-liter engine can consume a significant amount of oil.
Other engine complaints: Some models have experienced stalling, and the 3.6L engine can have issues with the oil cooler or radiator neck.

Brake problems

Premature wear: Owners report that brake pads and rotors wear out faster than expected.
Other issues: Problems include noisy brakes, sticking brake pedals, and ABS or ESC warning lights.

What are the symptoms of a clogged fuel filter?

Symptoms of a clogged fuel filter include difficulty starting the engine, rough idling, stalling, and poor acceleration. Other signs are decreased fuel economy, engine misfires, and potential fuel pump noise or failure due to the increased strain. A check engine light may also illuminate, though the specific codes are often generic.

Common symptoms

Difficulty starting: The engine may crank but not start, or it may start and then immediately die.
Rough idling: The engine may vibrate or shake while idling because it's not receiving a consistent flow of fuel.
Stalling: The vehicle may stall, especially when slowing down, at idle, or when under load.
Poor acceleration and power loss: The car may hesitate or feel sluggish when you press the gas pedal, especially when accelerating or climbing hills.
Engine misfires: The engine may sputter or misfire because some cylinders aren't getting enough fuel.
Decreased fuel economy: The engine has to work harder to pull fuel through a clogged filter, burning more gas.
Fuel pump issues: A clogged filter can cause the fuel pump to strain, leading to unusual whining or buzzing noises and potentially premature failure.
Check engine light: The check engine light may come on, and diagnostic codes may indicate a lean fuel mixture or a misfire.
