Dodge Neon fuel filter replacement
From Mechanical Database
All Dodge Neons have the same filter, location and changing procedure.
- Raise the rear passenger side of the Neon with a jack or a lift. If a jack is used, the car should be secured with jack stands.
- Crawl underneath (ahead of the rear tire), and locate the gas tank. It will have many fuel lines protruding form it. Follow them toward the front of the car about 8-10", and the fuel filter will be spotted. The fuel filter is barely visible due to the splash shield covering it.
- Remove this metal shield by removing the 3 bolts that hold it on. You will notice an odd looking contraption called a fuel filter. It is shaped like an oil filter, but a lot smaller, and has 3 tubes extending from it.
- The fuel pressure must be relieved before attempting to remove the old filter.
- Locate the Schraeder valve in the engine bay on the fuel rail. This is a test port and looks very similar to the air valve found on the tires.
- Obtain a water bottle or something of the sort to contain the gasoline that comes out.
- Take a nail or anything thing and sharp to press into the Schraeder valve.
- Once pressed gasoline will come out, contain it, and try to avoid letting it get all over the engine compartment.
- The inlet and outlet tubes and the other tube are permanently attached to the filter (as you will see when look at your new one). You must remove the first 2 tubes from the gas tank. The tubes use quick-connect fittings and if you look closely at them, you will see how they work. You may need a pair of pliers to remove them. The tabs are light blue colored and remove by applying pressure to both tabs at the same time, allowing the tube to slide off. The blue-colored plastic-connectors should also be removed if new ones are included with the filter.
- The last tube connects forward of the other two and removes in the same manner.
- There is one bolt now holding the filter itself to the frame rail. Remove this bolt.
- Apply a thin coat of engine oil to the fuel filter nipples before connecting to the new filter. This makes the insertion process smoother, and prevents damage to the o-ring seals inside.
- Bolt the new filter to the frame.
- Connect the new filter's tubes in the same order/way the old ones came off. The fittings are in different sizes, to prevent from them getting mixed up. Be sure to align the tabs on the connectors so that they properly lock onto the tubes. A loud audible click will be heard when a proper connection is made.
- Once you are SURE the fittings are all connected securely, get into your vehicle and prime the fuel pump. This is done by turning the key as if you're about to start the engine, but without activating the starter. Hold the key in the last position for a few seconds and repeat this 5 times. This will help build up some pressure. Afterwords, start the engine, this may take a bit of cranking.
- If the vehicle will not start there is a chance that one of the connections is not sealed properly, and the vehicle should be inspected for fuel leaks.
- If it does start, leave the car in idle and go back to the work area to make sure there is no fuel leaking, as a safety precaution.
- If there are no leaks, turn the engine off, and go back to replace the splash shield.
