Where is the fuel filter on a Chrysler Neon?
The Neon does not have a separate, user-serviceable fuel filter on the outside of the vehicle; the filtration is integrated into the fuel pump module inside the fuel tank, and access is via a panel under the rear seat or trunk floor depending on the model year.
In more detail, Chrysler designed the Neon with an in-tank fuel filter that's part of the fuel pump assembly. There is typically no inline filter along the under-vehicle fuel lines to inspect or replace. Service activity usually means addressing the entire fuel pump module rather than a standalone filter component, and the exact access method can vary by year and body style.
The following quick facts summarize the Neon’s fuel filtration setup and related service implications.
- Location: The filter is inside the fuel tank, attached to the fuel pump module. There is no separate external inline filter to locate or replace.
- Access method: Access is provided through a panel under the rear seat cushion (or, in some trunk-floor configurations, a panel in the floor behind the rear seat). You must remove the panel to reach the pump module.
- Replacement considerations: If filtration is an issue, most repairs involve replacing the entire fuel pump module, since the filter is not serviceable as a standalone part. Depending on year and model, this may require lowering the tank and proper safety precautions.
Because the filter lives inside the fuel tank, routine external inspection isn’t possible in the way it is for some other cars. If you’re experiencing fuel-delivery symptoms—such as erratic performance, stalling, or starting problems—diagnose the pump module, wiring, and fuel pressure rather than attempting an external filter replacement.
Accessing the fuel pump module on a Neon
To reach the filter/pump module, locate the access panel beneath the rear seat or in the trunk floor, depending on your Neon’s year and body style. Remove the panel, disconnect electrical connectors, and follow the service manual for removing the pump assembly. Always work with the fuel system depressurized and in a well-ventilated area.
Safety and best practices
Relieve fuel pressure before opening any lines, disconnect the battery to prevent sparks, and use appropriate safety gear. Dispose of any spilled fuel properly and avoid open flames or smoking nearby during service.
Replacement considerations by generation
Across the Neon’s production span (1994–2005), the design relied on an in-tank filter within the pump module. There is no standardized external filter to replace separately, so if a filter-related issue arises, technicians typically replace the pump module as a unit. Always consult the specific year/service manual for the exact procedure and tank-access instructions.
Summary
The Chrysler Neon stores its fuel filtration inside the fuel tank as part of the fuel pump module, with access via a panel under the rear seat or trunk floor. There is no conventional external fuel filter to locate or replace, so addressing fuel delivery issues generally means inspecting or replacing the pump module in accordance with the vehicle’s service guidance.
