    if it is the fitting then you will need to replace it by replacing that section of will need a flearing tool and a special crimping tool to put the proper end on the filter side the other side you can just put flear nuts and a union to connect the two lines maybe able to get the tools at your local parts store or from a specialty toos can also buy from snap-on tools but verry expensive from snap-on

How to change 2003 kia optima sedan fuel filter

The fuel filter location varies with engine size on the Kia Optima. The 1.5-, 1.6- and 2.4-liter engines have the fuel filter located under the car in the front left corner of the fuel tank. The 1.8-liter engine has the fuel filter located on the driver's side firewall. All the filters have the same replacement procedure. There are actually two filters on the Kia Optima. A filter called a strainer is attached to the intake side of the fuel pump inside the fuel tank.

To change the filter follow this procedure:-

•Lift the hood and remove the cap on the fuse and relay box located on the driver's side fenderwell. Look at the bottom of the cap for the location of the fuel pump relay within the box. Pull the fuel pump relay out and lay it sideways in the box.

Start the engine. It is not likely to start and even if it does it will only run for a second since the fuel pump relay has been removed, which disabled the fuel pump. This procedure will drop the fuel pressure in the fuel line. Raise the rear of the vehicle with the floor jack and support it by the frame with the jack stands. This is for engines 1.5, 1.6 and 2.4.

Remove the fuel lines on both ends of the fuel filter. Use the scribe--a long pointy needle--to lift the white retainer straight up located in the center of the connector. This releases the fuel line from the fuel pump. Do the same to the other side of the fuel pump.

Remove the bolt in the center of the fuel pump retainer bracket using a 10 mm socket. Pull the fuel pump out of the bracket.

Insert the new fuel pump into the retainer bracket. Make sure that the inlet side faces the fuel line to the fuel tank and the outlet toward the fuel line to the engine. Install the fuel pump and bracket and tighten the bolt.

Place a white retainer clip that came with the filter into the holes in each of the connectors. Just push it in enough to snap the bottom ends of the clip in place. The clip should now be standing straight up with just the bottom tips in the connectors. Push each of the fuel lines into the filter one at a time. Holding the fuel line tightly into the filter, push the white retainer clip down to lock the fuel filter and fuel line together. Lower the car and replace the fuel pump relay. Start the car and check for leaks.

NEVER SMOKE WHEN WORKING AROUND OR NEAR GASOLINE! MAKE SURE THAT THERE IS NO ACTIVE IGNITION SOURCE NEAR YOUR WORK AREA! 1970-83 Carbureted Engines The fuel filter is located on the right inner fender in the engine compartment. It is a disposable cartridge type.
  1. Using a pair of pliers, expand the hose clamp on one side of the filter, and slide the clamp further down the hose, past the point to which the filter pipe extends. Remove the other clamp in the same manner.
  2. Grasp the hoses near the ends and twist them gently to pull them free from the filter pipes.
  3. Pull the filter from the clip and discard.
  4. Install the new filter into the clip. Push the hoses onto the filter pipes, and slide the clamps back into position. Start the engine and check for leaks. Fig. 1: Fuel filter - 1970-79 85851035.gif
    Fig. 2: Fuel filter - 1980-83 85851036.gif
1984-86 Carbureted Engines The fuel filter is located on the inside of the frame above the left rear spring front shackle. Changing the filter is VERY awkward. Since it is in-line and below tank level, fuel will pour from the fuel lines when they are disconnected from the filter. The only way of preventing this, is to siphon all of the gasoline from the tank before replacing the filter. Another possible method is to clamp and plug the fuel line, but this is not recommended because of the danger of leaking fuel or damage which could occur to the fuel line when clamped. It would, therefore, be a good idea to run the tank almost dry before changing the filter. Once the tank is dry, disconnect the fuel lines at the filter, unbolt the old filter and install a new one. Reconnect the fuel lines, fill the tank, start the engine and check for leaks. Fig. 3: Fuel filter - 1984-86 85851037.gif

Fuel Injected Engines WARNING
Never attempt to remove the fuel filter without first relieving the fuel system pressure!
  1. Release the fuel pressure from the fuel line as follows:
    1. Remove the fuel pump fuse at the fuse box.
    2. Start the engine.
    3. After the engine stalls, crank the engine two or three times to make sure that the fuel pressure is released.
    4. Turn the ignition switch OFF and reinstall the fuel pump fuse.
  2. Loosen the hose clamps at the fuel inlet and outlet lines then slide each line off the filter nipples.
  3. Remove the fuel filter.
  4. Replace the fuel filter. Always be sure to use new hose clamps. Fig. 7: Fuel filter - 1986-88 VG30i 85851038.gif

How do you change fuel injectors


For a 2003 it is on the frame rail under the drivers side door. Don't bother taking off the black holster that holds the fuel filter/injector onto the frame rail.
1 )Simply unscrew the nuts on both sides of the fuel filter/injector. It will be under pressure. Wear safety goggles. A couple of cups of fuel will spill.
2) Look at the fuel line on the engine side. Notice the clip holding in the line. Remove the line from the clip.
3) Remove the fuel lines from the filter starting with the side toward the engine. This side has more play/laxity in the line.
4) Slide out the fuel filter/injector from the black holster.
5) Slide in the new fuel filter/injector with the flow directional arrow pointing toward the engine.
6) Attach the fuel line to the filter starting with the tank side first. Don't force it and thread out the fittings.
7) Attach the engine side fuel line. The fitting would come together by hand screwing the male into the female end. I did have to use a wrench to gently start it.

Take care.

How do I change the fuel filter on my 2000 Excursion? New filter has plastic clips

You need a small pocket screw driver and pinch the opposite end of the clamp to remove. Normally they come with new clips as the old ones break off. And if the filter has been on a long time the clips can actually wear out and can leak fuel if you don't replace also have to remove the one or two mounting bolts holding it on.

Need to change fuel filter on 98' Mercury mountaineer all wheel drive, but do not know how on this kind.Engine size is 5.0

The fuel filter will be located under the driver side door tucked inside the frame rail. The filter should have 2 or 3 plastic clips you can pinch the end of the clips together and pull the clips right out.

I suggest replacing the clips because they get brittle and break easy. after you remove the clips you pull the fuel lines off. there will be pressure on these lines you can release the pressure by pushing the fuel valve stem located on your fuel injection rails underneath the hood either way you will have gas all over so dont do it while your engine is hot or near any flames, sparks or anything that will ignite the gas. (If you do not release the pressure be careful not to get gas in your eyes as it will spray for a secound or two).
After you remove the lines there may be a bolt on the outside of the frame rail you have to remove to remove the filter if not it will have a clamp around it and you just loosen it and slide it out. However on some models like mine there are not any plastic clips there are metal ones on the outside that clip onto the filter and the fuel line.

With ones like this there are metal retaining clips on the inside of the line as well it will take alot of force to pull them off and you will notice how there are two or three little metal pieces sticking out of the line, with a small screwdriver try to bend them back in if you cannot you will have to buy new ones from a autoparts store (orliley autoparts or advanced auto parts have them, the dorman part number is 800-017), they are called retaining clips, without them the lines will leak like crazy and you will not be able to drive, if you give up the new lines are available at the dealer for about 100 apiece and are about 6 hours of dealer labor to put in, so be carefull

Fuel filter at foer escape 2001 4w chenging

start the engine  open the hood and remove the system fuse 
the engine will stall, the pressure is now relieved 
the fuel filter is in front of the fuel tank, driver side 
wear gloves/saftey glasses and have a fire extinguisher available (who knows!) the filter will have 2 hoses attached at either end. white/yellowish clips attach these hoses. feel for the top of the clip and push the 2 ends in and down. you may have to use a screw driver to pry the bottom of the clip as well. pull the bottom of the clip down, it will not come out of the coupling completely. repeat for both lines, pull lines firmly off of filter. unscrew filter from hose clamp. approx 6-10 oz of fuel will spill from lines and filter. you should use a pan. install new filter, in same direction as last. insert new clips into coupling, discard old. clip on "out" side may be reused if an R clip. tighten clamp on filter, attach hoses. push in clips to lock. inspect for leaks, wipe entire area clean of fuel. insert fuse and attempt to start. Cycle the ignition to run and off three times before starting to pressurize the fuel line. Good luck and hope this helps.
