My 1 ton Ford van has steel braid fuel lines which push onto the fuel filter, and lock on the little upset made onto the filter inlet, and outlet. The lines move back and forth about a quarter inch, but won't pull off. How do you unlock whatever is holding them on?

Instructions

• Open the hood to access the engine compartment. Locate the fuse panel behind the battery. Open the relay cover and locate the fuel pump relay. The cover will have a diagram to pinpoint the exact relay.
• 2Pull the relay out of the fuse panel and place it to the side. Start the car and allow it to idle until it stalls out. This will depressurize the fuel system.
  
• 3
  
• Locate the fuel filter underneath the car directly under the rear driver side door. The filter will be a foot in front of the fuel tank.
  
• 4Unscrew the outlet side with an open-end wrench. Use a second wrench to hold the stationary nut on the filter; this will prevent the filter from turning. Pull the fuel line away from the filter.
  
• 5Squeeze the clip on the inlet side by hand and pull off the inlet pipe of the fuel filter. Pull the fuel line away from the fuel filter.
  
• 6Unbolt the filter from the mounting bracket to release the filter. Replace with the new filter. Tighten the mounting bracket with a socket wrench.
  
• 7Push the inlet line onto the fuel filter by hand. The line will lock in place.
  
• 8Screw the outlet line onto the fuel filter by hand. Tighten with a wrench to ensure the line is secured. Use a second wrench to prevent the filter from turning.
  
• 9Insert the fuel pump relay into the fuse panel. Close the fuse panel cover back onto the fuse panel.
  
• 10Turn the ignition to the "run" position and hold for three seconds. This will engage the fuel pump to prime the line. Turn the key off and repeat again. Attempt to crank the car to circulate the fuel into the fuel line.
  
• 11Allow the car to idle for five minutes. Inspect for any fuel leaks before turning off the car.
  

You will need to remove the gas tank and replace the fuel level sensor inside the fuel tank.
The level sensor is part of the electric fuel pump "module" Here is how to change that part.

• 1. Start the van's engine. Open the fuel cap and remove the fuel pump relay from the engine's fuse box. Look for the engine to stall, signaling that the fuel pressure is gone.
  
• 2Disconnect the van's negative battery cable.
  
• 3. Unbolt the fuel tank's straps and lower the tank just enough to access the fuel pump flange. You can have a second person lower the tank, but it might be easier to use a floor jack with a wood block.
  
• 4Remove the small locking pin on the pump's electrical connector with needle-nose pliers, and disconnect the electrical connector. Press the retainer tabs on the fuel lines and disconnect them from the pump.
  
• 5Unscrew the pump's locking ring with a strap wrench or a similar hand-made tool that can grip the large ring and turn it.
  
• 6Pull the water pump out of the tank, then remove and discard the O-ring from the fuel tank.
  
• 7Pry back the locking tabs connecting the inlet filter to the pump reservoir using a thin screwdriver and remove the filter. This is only needed if this filter is in good condition and you must transfer it to the new pump.
  

Installation

• 8Lubricate the O-ring for the filter with engine oil and connect it to the outlet of the filter. Push the filter onto the pump reservoir's inlet and make sure the locking tabs engage.
  
• 9Install a new O-ring onto the seating hole on the fuel tank.
  
• 10Insert the pump module into the tank, tilting it at an angle and making sure you don't damage the filter or the pump float. Make sure the module is properly seated.
  
• 11Screw the retaining ring into position on the pump module.
  
• 12Reconnect the fuel lines to the pump using their quick-connect fittings and the electrical connector with its locking pin.
  
• 13Connect the tank back to the van using its straps and strap bolts.
  
• 14Reconnect the fuel pump relay and negative battery cable
  

Change the Fuel Filter the process is

1

Park the van on a flat, level surface. Ensure the parking brake is set.

2

Open the hood to locate the fuse panel. The fuse panel is located by the battery. Find the relay for the fuel pump and pull it out by hand.

3

Start the van and allow it to idle until it stalls out. This will depressurize the fuel system.

4

Locate the fuel filter under the van. The filter is located by the driver door mounted along the frame rail.

5

Disconnect the inlet fuel line with the quick-disconnect tool. This tool can be purchased at any automotive-parts stores. Place the tool over the connection and pull it toward the filter. This will release the fuel line from the filter. Repeat to release the line on the outlet end. Place a piece of masking tape over the inlet line to help remember which line is which. The inlet line is the line coming from the fuel tank into the filter. The outlet line is the line that runs to the engine from the filter.

6

Unbolt the filter from the bracket assembly. Slide the filter from the bracket.

7

Slide the new filter to the mounting bracket. Tighten the bracket with a socket wrench. Ensure the arrow is pointing toward the front of the van. The arrow designates the direction of the fuel flow.

8

Push the inlet line onto the filter. The line will lock in place. Ensure the tape is removed before installing. Connect the outlet line to the filter. It will lock in place also.

9

Insert the fuel pump relay back into the fuse panel. This will pressurize the fuel system.

10

Turn the ignition to the "start" position and allow the fuel pump to prime itself and push fuel through the lines. Attempt to start the van; it may not start right away. Once the van has started allow it to run for five minutes and observe for leaks.

Hello there, here are a few key notes to assist you:

• Open the hood for access to the engine compartment. Depressurize the fuel line by pulling the fuel pump relay. The relay is located in the fuse panel under the hood behind the battery.
• Start the truck and allow it to stall. The fuel system is depressurized. Insert the relay back into the fuse panel.
• Locate the fuel filter by tracing the fuel lines coming out of the fuel tank. The filter will be located a foot from the tank under the truck on the driver side.
• Unscrew the inlet and outlet lines by loosening the fuel line with a line wrench. Hold the filter in place by holding the nut on the filter with a second line wrench.
• Pull the filter out of the mounting bracket by sliding it out and away from the bracket.
• Slide the new filter into the mounting bracket. Ensure the arrow on the filter is pointing toward the front of the truck, as it designates the direction of fuel flow.
• Screw the inlet and outlet lines onto the filter by hand. Tighten with a line wrench. Use a second line wrench to hold the filter still while tightening.
• Start the truck by turning the ignition to the "Start" position. Hold the key in this position for two seconds to allow the fuel pump to push fuel through the lines. Repeat this until the truck starts.
• Allow the truck to idle while inspecting the filter for any leaks. Inspect around the filter and the fuel lines.

Good luck...

Follow the steps care fully

Open the hood and relieve the fuel system pressure. On the fuel rail, right before the first fuel injector, locate the Schrader valve-similar to a tire air valve-on the inlet fuel line. Using a small screwdriver, depress the stem inside the valve while covering the valve with a shop rag to catch the squirt of fuel.

Raise the back of the vehicle using a floor jack and support it safely on jack stands.

Locate the fuel filter along the frame rail-passenger side-of the vehicle, near the fuel tank.

Unplug the quick-connect fuel inlet line on the back of the filter by pressing the lock tabs. Push the connector towards the filter and then pull to disconnect the fuel supply line.

Disconnect the outlet fuel line from the filter-the line going toward the engine-by using a backup wrench to hold the line nut while disconnecting the lock nut on the filter with a tube wrench.

Remove the filter from its mounting bracket and install the new filter in place, making sure the arrow on the side of the filter case points toward the engine.

Install the outlet fuel line. Tight the lock nut finger tight, then hold the fuel line nut with the backup wrench and tight the lock nut with the tube wrench. Make sure not to over tighten the nut to prevent fuel leaks.

Press the fuel supply line fitting against the small tube at the back of the filter until the lock tabs snap in place.

Lower the vehicle, start the engine and check for leaks.

Go to the end of the driver door (just a reference point). Look under the body of the van. You will see the fuel filter (large round tubular shaped object) with a fuel inlet and outlet. you have to have a special tool (you can rent or buy at Autozone) to remove the fuel line. With the tool it is very easy. Replace with a new filter and snap your fuel lines back on. Make sure the arrow showing which way the fuel flows is pointing toward the front of the vehicle. Hope this has helped you.

For 1995 Ford Truck E150 1/2 ton Van 5.8L EFI 8cyl the Fuel Filter is located under vehicle, driver side, below seating area, mounted on frame in fuel line.

Hope helps (remember comment and rated this).

Fuel filters and elements are serviced by replacement only. Some vehicle manufacturers recommend fuel filter replacement at 30,000 miles (48,000 km). Always replace the fuel filter at the vehicle manufacturer's recommended mileage.
The fuel filter replacement procedure varies depending on the make and year of the vehicle and the type of fuel system. Always follow the filter replacement procedure in the appropriate service manual. The photo sequence below shows a typical procedure for relieving fuel pressure and removing a fuel filter.
Removing a Fuel Filter on an EFI Vehicle
Disconnect the negative cable at the battery.
Loosen the fuel tank filler cap to relieve any fuel tank vapor pressure.
Wrap a shop towel around the Schrader valve on the fuel rail and remove the dust cap from the valve.
Connect the fuel pressure gauge to the Schrader valve.
Install the free end of the gauge bleed hose into an approved gasoline container, and open the gauge bleed valve to relieve the fuel pressure.
Place the vehicle on the hoist and position the lift arms according to manufacturer's recommendations. Then raise the vehicle.
Flush the fuel filter line connectors with water, and use compressed air to blow debris off and away from the connectors.
Follow the recommended procedures for disconnecting the fuel inlet connector.

Installing Fuel Filters
In-line fuel filters are installed in the fuel line. In carbureted engines, the in-line gasoline filter is usually installed between the fuel pump and the carburetor. In vehicles with a fuel injection system, the location of the fuel filter is determined by the manufacturer. An arrow on the filter shows the direction of fuel flow.

• To install a new filter, begin by wiping the male tube ends of the new filter with a clean shop towel.
• Apply a few drops of clean engine oil to the male tube ends on the filter.
• Check the quick connectors to be sure the large collar on each connector has rotated back to the original position. The springs must be visible on the inside diameter of each quick connector.
• Then install the filter in the proper direction and leave the mounting bolt slightly loose.
• Install the outlet connector onto the filter outlet tube and press the connector firmly in place until the spring snaps into position.
• Grasp the fuel line and try to pull this line from the filter to be sure the quick connector is locked in place.
• Then, do the same with the inlet connector.
• Now tighten the filter retaining bolt to the specified torque.
• Once everything is connected, lower the vehicle, start the engine, and check for fuel leaks at the filter. NOTE THIS IS FOR A 3/4 TON 5.8L
  

On these vehicles, the fuel filter is located on the fuel line to the carburetor. Special care should be taken when removing and installing the fuel filter, not to bend or distort the fuel line in any way.

1. Remove gas cap to relieve any pressure that may be present in the fuel system.
2. Remove the air cleaner bonnet assembly.
3. Using a backup wrench on the return line fitting on the top of the fuel filter, remove the fuel line with a flare nut wrench.
4. Using a backup wrench on the fuel filter inlet fitting, remove the fuel line from the fuel filter with a flare nut wrench.
5. Using a backup wrench on the fuel filter outlet fitting, loosen the fuel line and remove the fuel filter from the engine with a flare nut wrench.

To Install:

1. Apply a drop of engine oil to all the fuel line nuts and flared ends.
2. Position the fuel filter with flow arrow on the filter directed towards the fuel line going to the carburetor.
3. Finger-tighten the fittings at the fuel filter outlet, inlet and return line into the top of the filter.
4. Using a backup wrench on the fuel filter fittings, tighten the fuel lines in the following sequence:
   1. Tighten the outlet and inlet line nuts to 15-18 ft. lbs. (20.0-24.0 Nm)
   2. Tighten the nut on the return line at the top of the filter to 6-9 ft. lbs. (15-18 Nm).
5. Inspect the fuel lines and carefully adjust if they are interfering with the carburetor, air pump, or fuel filter housing.
6. Start the engine and check for fuel leaks at all the connections. Retighten if necessary.
7. If removed, install the air filter bonnet assembly.
