How do i change the fuel filter on a 1992 Ford F 250 7.3 Liter diesel.

fuel filter problems come in slowly as in loss of power. It it just died and will not start I would be looking elsewhere for the problem. A good place to start would be the fault codes to check for cam/crank position sensor faults, immobiliser operation,timing belt condition. If you ran the fuel too low it may have air in the system that will have to be bled out. Best have an accredited diesel shop specialist look at it.

2006 f350 6.0 diesel hesitates, stutters under light load

These trucks have a history of epg valve problems . Sure sign is thick black smoke , Also you are suppose to drain water from filter case with a 6mm Allen wrench . Its on frame rail under drive seat . That filter is often over looked to . If the water hasn't been drained every month it destroys the injectors . My bet is the fuel filters . One filter underneath an one on top of motor .

My 2005 F-250 is reading water in fuel. Where is the valve to remove the water?

You can locate the horizontal fuel-conditioning module (HFCM) mounted to the frame rail underneath the driver's seat. Place a drain pan under the HFCM. Turn the fuel drain lever outwards and let the HFCM drain into the pan until clean fuel is observed coming from the module, then close the drain lever.

I have heard of people having to do this 2 or 3 times over the course of a week to get the light to remain off.

It may be a good idea to replace the filter element while you are in there as follows:

  1. Remove the fuel-filter lid from the HFCM with an adjustable wrench turned in a counterclockwise direction. Place the lid aside. Pull the old fuel filter from the HFCM and clean the filter mating surfaces with a clean rag.

  2. Insert a new filter element into the HFMC until it is fully seated. Remove the old "O" ring gasket from the fuel-filter lid and discard it. Stretch a new "O" ring gasket (included with a new fuel filter) over the lid and work it into the groove. Lubricate the gasket with clean diesel fuel applied with your finger. Tighten the cap in a clockwise direction onto the HFCM with an adjustable wrench. Remove the drain pan from under the vehicle.

  3. Open the hood and remove the fuel-filter housing lid on top of the engine with an adjustable wrench turned in a counterclockwise direction. Lift the old fuel-filter element from the housing and clean the filter mating surfaces with a clean rag.

  4. Push a new filter element into the housing until it is fully seated. Replace the "O" ring gasket on the lid in the same fashion as the HFCM fuel-filter lid and lubricate with diesel fuel. Screw the lid back on and tighten with an adjustable wrench. Close the hood.

Where safety goggles and gloves and good luck.

Where is the fuel filter located on a 2006 Ford Freestar

Hello there:
if you have your filter great or if not use FRAM G8018 from WalMart for around $8 and then get the fuel line removal tool from Pepboys or autozone for $7. Tool should be 5/16" fuel line disconnect.

  • No need to raise the vehicle.
  • Due to the amount of fuel,that could come out I would use battery powered work light, not 110V AC for safety reasons.

  1. Pull relay #53 from fuse panel under hood. This disconnects fuel pump.
  2. Start engine and let it die. Restart again.
  3. Filter is located under passenger side center seat.
  4. sometimes more fuel will come out than expected. so make sure to Use a clean oil drain pan, or coffee can to catch the excess fuel .
  5. Use tool to disconnect fuel lines. Loosen single screw/clamp. Note the direction of filter.
  6. Replace filter, tighten clamp screw, reconnect fuel lines.
  7. Replace relay. turn the key to the on position for 45 seconds to get the fuel back in the lines
  8. Test by starting car, shut it down, look for leaks. If no leaks start car again, let idle and inspect for leaks again.
Hope this is very helpful for you.
Best regards Michael

2006 ford F-250 super duty water in fuel light came on after hard freeze

I don't have any specific info on the the Ford, but I've had a VW diesel for years.

Best bet would be to add some Power Service or other fuel conditioner. Might also change the fuel filter to be sure you don't have water there. The filter might have a petcock or drain at the bottom also. You would just open that and collect a cupful or so of whatever comes out. Will likely be a mix of fuel and water.
