When called the the dealer to have my fuel filter changed at 30k miles, I was told the 01 maxima does not have a fuel filter. I found this quite strange and called another dealer. The second dealer told me it does have a fuel filter, but it's inside the fuel tank and doesn't need to be replaced until 100k miles. Anyone know what the real answer is? Thanks!

Thanks JJS!

 

jjs' link has good info but the dealership was right in that nissan says it can go 100k. the problem is that they say the spark plugs can go that long too. i cant remember the member's name but he had the fuel filter replaced in his 5th gen around 60k and reported better fuel fileage and better response if i remember correctly. i will look into replacing around the same interval. the filter itself can be had for around 15 bucks but the install shouldnt be hard just tedious to get everything out correctly.

 

Courtesy Nissan's site says that the fuel filter is considered a 'replacement part,' so it says it 'probably never' needs to be changed as part of one's maintence routine.

It's a pain to replace from what I hear. Here's some instructions, if you wish to try it yourself:

Fuel Pump, Fuel Level Sensor Unit and Fuel Filter

REMOVAL:
1. Release fuel pressure from fuel line.
2. Remove rear seat bottom.
3. Remove inspection hole cover located under the rear seat.
4. Disconnect electrical connector.
5. Remove the quick connectors.
6. Remove the six bolts.
7. Pull out the fuel level sensor unit and fuel pump.
- Do not damage the arm of the fuel level sensor and fuel tank temperature sensor.
8. Remove flange of fuel level sensor unit and fuel pump.
- Using a screwdriver, remove the snap fit portion.
9. Push fuel level sensor flange.
- Using a screwdriver, remove the snap fit portion.
10. Pull up the fuel level sensor.
11. Remove fuel filter from chamber.
- Using a screwdriver, remove the snap fit portion.
12. Remove pressure regulator clip, then pull out pressure regulator.
13. Remove fuel pump, then push down the fuel pump.
14. Remove packing from fuel pump.
15. Remove the pump support rubber from the fuel pump.


INSTALLATION:
Install in the reverse order of removal paying attention to the following.
- Install the fuel filter and fuel pump with the tabs aligned, make sure a click sound of secure engagement is heard.
- Securely connect the harness connector of the fuel pump.
- Install the pressure regulator O-ring as follows.
CAUTION:
- When replacing, always use a new O-ring, packing and clip.
- Handle it with bare hands. (Do not use gloves.)
- Visually check the O-ring, mounting parts and mating parts for foreign materials and flaws.
- Before installing, apply new engine oil.
- To avoid damage, do not apply an excessive force (pulling or starching).

- Install the pressure regulator as follows.
1. Insert the clip to the groove of the regulator.
2. With the clip installed, insert the regulator straight by matching the fuel filter protrusion and the clip notch.
3. Make sure that the fuel filter protrusion and clip notch are securely engaged.

Peace.

 

I have done it and its really not hard. I do agree with the do it slow comment. As you WILL get gas everywhere if you rush and dont pay attention. I also recommend doing it when the fuel gauge is under 1/4. I DO recommend changing WAY earlier than 100K, as at 28K mine was el crappo!

 

I would add to Step 1 : Remove fuel pump fuse. Try to start car until the engine will not turn over. That's it.
