XenonZcar.com - Z31 Fuel Filter Replacement
You should replace the fuel filter on your Z every 30,000 miles or 2 years. A clogged fuel filter can result in lost power and lower fuel economy.
Equipment Needed:
- Phillips screwdriver
- Nissan fuel filter part #16400-Z31002 or equivalent
- Towel
Procedure:
- Start the engine and let it idle.
- Remove the floor mat from the hatch area (where the toolkit is located).
- Disconnect the blue wiring harness, this will cut off the fuel pump (the car will stall).
- Try to start the car a few times to remove any remaining fuel pressure.
- Turn off the car.
- The fuel filter is located on the passenger side of the engine.
- Loosen the fuel hose clamps (2) and the filter retaining clamp screw.
- Make sure you note the flow direction of the old filter before removing it (fuel goes in the bottom and out the top).
- Wrap a rag around the filter to absorb any remaining fuel.
- Hold the filter with one hand and remove the hoses starting with the top hose with the other.
- To remove the filter pull it out of the retaining clamp.
- Insert the new filter making sure to note the proper flow direction (Out should be up).
- Reconnect the hoses starting with the bottom one. Make sure to tighten the hose clamps sufficiently.
- Complete the job by tightening the clamp around the filter.
NOTE: After you have replaced the fuel filter, start the car and look for any leaks. If there are none, proceed to drive the car a short distance and then look for leaks again.
