The fuel filter on the Mazda 3 plays a huge role in the operation of the car engine. Its main task is to trap various particles of dirt, water and rust. Such contamination appears when refueling fuel, especially if it is of poor quality. The fuel filter requires timely replacement, which increases engine life and has a positive effect on the operation of the vehicle as a whole.
Necessary
- - spanner key;
- - open-end wrench.
Instructions
Step 1
The signal to replace the fuel filter on the Mazda 3 is the special behavior of the transport at high speeds. When driving, jerks begin to be felt. Over time, they are felt even at minimum speed. Before replacing the fuel filter, release the pressure from the power supply system, and then be sure to disconnect the negative terminal from the battery.
Step 2
If your car's stereo has a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery.
Step 3
The fuel filter on the Mazda 3 is located in the engine compartment of the vehicle. As a rule, it is attached to its rear bulkhead. To make it easier for yourself to access the filter, remove the air cleaner cover. It must be assembled with an air outlet.
Step 4
Wrap the spigot connections that are to be undocked with a rag. This is to ensure that residual fuel pressure does not spill out when the connector is released. Also prepare old newspapers in advance, which will be useful in the future for collecting spilled fuel.
Step 5
Secure the nut to the fuel filter to prevent it from turning. Then, using a second wrench, loosen the hollow bolt located on the union connection of the fuel inlet line. Now from the fuel filter on the Mazda 3, carefully disconnect the pressure line and remove the sealing washers, which will need to be discarded, as they cannot be reused.
Step 6
Now loosen the union nut of the outlet line socket. It is located at the bottom of the filter. Then disconnect the line. Loosen the two tie bolts and remove the fuel filter from the bracket clamp. If necessary, remove the bracket itself.
Step 7
Place a new fuel filter in the retaining clip and lightly tighten the bolts. Be sure to check the correct installation of the filter, while focusing on the arrow, the direction of which must coincide with the direction of fuel flow.
Step 8
Connect the fuel line to the filter from its lower side, remembering to replace the sealing washer before that. Screw on and lightly tighten the flare nut, then attach the pressure line to the top of the filter and tighten the hollow screw. In this case, the filter must be kept from turning. Fully tighten the lower connector flare nut and the retaining clamp pinch bolts.
Step 9
After installing the filter, connect the negative wire to the battery, then, after turning on the ignition, check all the components of the power system for fuel leaks.
