How often should we change fuel filter for Nissan Teana


hi Drkmaniir.
Changing out your car's fuel filter may not be at the top of your routine auto maintenance list like oil changes and tire rotations. Heck, you may not even know what a fuel filter is.
But mechanics say periodically replacing fuel filters is a good idea because it helps keep your fuel pump and engine running smoothly.
The fuel pump is designed to catch particles, debris or impurities in the gas tank before the fuel reaches the pump, to ensure only clean gasoline reaches your engine.
"They get overlooked a lot and then can go unchanged for quite awhile with no problem," says Frank Satriano, owner of Coachman Automotive in Clearwater, Florida. "Some cars have them in the gas tank and never get serviced, so it just depends on the car and what the manufacturer recommends."

It's important to note that many newer vehicles come with a non-serviceable filter located in the fuel tank, so you'll want to check your owner's manual to see whether it needs to be replaced.

Why you should replace your fuel filter

Like any filter, debris will clog it up over time. This causes the fuel pump to work harder, which can in turn lead to it breaking down. Engines can also be damaged from contaminated fuel.
"Today's vehicles are equipped with more state-of-the-art fuel injectors, which have very tight clearances," says Katy Kreitzer, service manager of Kreitzer's Automotive Service in Enola, Pennsylvania. "If debris enters the fuel injector, it can clog the fuel passages and damage the injector. This may also result in a dripping of fuel instead of a fine spray mist that is required for efficient combustion."
According to Ford Motor Co., you may want to think about changing the filter if the car is difficult to start, idles rough or stalls, has sluggish acceleration, decreased fuel economy or has a tank of bad gas.

"Thirty thousand miles is a good idea for a ballpark interval."Bob Waeiss, owner of Integrity Automotive in Carmel, Indiana, says the old best practice would be to replace the filter every 30,000 miles but that's no longer the norm, he says."As clean as most fuels are today, you could push that off to 60,000 or 90,000 miles," Waeiss says. "Replacing a fuel filter for the first time at or above 100,000 miles may cause a fuel pump failure. Not sure why, other than over time the filter becomes restricted and the pump has to work harder to push the fuel through the line. When a new filter is installed, the pump can't handle the free flow, and it stops pumping."

However, Kreitzer says prices for a new fuel filter typically costs between $100 and $150, which includes parts and labor.According to Auto Service Costs, the average cost for a mechanic to install a new fuel filter is between $53 and $165, while ordering the part itself can cost around $14 to $60.

Where is the fuel filter located on a 2001 Hyundai elantra


That fuel filter is in the fuel tank, attached to the fuel pump. Not a very difficult job. Remove the rear seat cushion, then remove the access panel to the pump. Remove the gas cap to relieve any pressure. Remove the ground wire and fuel lines, then remove the filter.

Where is fuel filter located on 1996 lexus es 300, and how to replace it?


the fuel filter is located in the engine compartment on the driver's side. You have to take off the air vent connected to the air filter to get better access. Then, unscrew the bolts on the top and on the bottom of the filter and unscrew the screws on the metal belt wrapped around the filter to release it. Excess petrol will spill out. Once this is done you can put the new filter in place and you are finished. Replacing the fuel filter in and of itself is very easy but the location on this particular model makes it much more difficult and tedious.

prev.gif next.gif Fuel Filter The fuel filter is part of the fuel tank module. (in the fuel tank)

It's kind of difficult to drop a fuel tank and replace the fuel tank module due to the weight and danger of gasoline catching fire or exploding.

1987 Cutlass Supreme not turning on. Think fuel system?


Fuel Filter REPLACEMENT Gasoline Engines The fuel filter is located behind the fuel inlet connection on the carburetor. On 1976–87 vehicles fuel filters incorporate a check valve and are not interchangeable with earlier years. Replace the fuel filter every 15,000 miles (24,135 km), or sooner if engine flooding is a problem. Fig. 1: Hold the large fuel inlet nut on the carburetor while using a flare wrench to loosen the line connection 86681247.jpg
  1. Using an open–end wrench (preferably a line or flare nut wrench), loosen the fuel line connection from the larger fuel filter nut. You will have to hold the other nut with a wrench to keep it from turning. Most of the time these units are quite difficult to remove. It is a good idea to apply a lot of penetrating oil to the threads and then tap the nut lightly.
  2. Once you have the fuel line disconnected from the carburetor, remove the larger nut from the carburetor with a box–end wrench or socket.
  3. Remove the filter element and spring from the carburetor.
  4. Check the element for blockage by blowing through the fuel inlet end. If the element is good, air should pass through easily.
  5. Once you have checked and/or replaced the filter, reinstall the carburetor nut and the fuel line. Be careful not to strip the threads. Fig. 2: Install the new spring and filter in the order they were removed 86681248.jpg

I cant locate the fuel filter on my 2005 1.5 petrol almera??? where is it???


the early models had the fuel filter mounted in the engine bay against the firewall. follow the fuel lines from the motor to the firewall. if there is no filter there then it is the late model and the filter is part of the fuel sender unit, this is mounted in the fuel tank and includes the fuel pump. this type is difficult to replace, and sometimes requires replacment of the entire sender unit.
Best way to tell is to call a nissan spare parts dept witn you VIN number and ask if this filter is replacable.

Fuel does not seem to be reaching engine -- difficult to start, idles rough, engine does not respond to acceleration


You either have a clogged filter or fuel pump is bad. The filter is the cheapest to replace. You can do both yourself with common tools. Post if you need instructions.
