Make sure the fuel selector switch is in the right position for the proper tank. Double check that the tanks have not been reversed according to the selector switch. You could be pumping out of the wrong tank

As long as the fuel pump is running you must have a restriction in a fuel line.
good luck

My gas tank leaks. How do I go about replacing it? It seems to have three fuel lines to the tank. One is a small diameter line and the other two are larger, I am assuming one of these might be a return...


if you take and clamp off the hoses and remove them from the tank,then support the fuel tank,remove the fuel tank holding straps then lower the tank,disconnect the wiring and make sure there is nothing else connected to the fuel tank,remove fuel tank transfer any components to the new tank and re-install.

Fuel leaks from rear tank to front.


The leaking from one tank to another was covered by a recall from Ford. Not sure if they still foot the bill for installation of the required check valves. These are still available from the dealership. The rear one is the hardest to install. The check valve can be installed without pulling the rear tank. As for your front sender I would clean all of the connections to the sender and make sure it has a decent ground. If it still only reads at the 1/4 tank level you will have to replace the sender to rectify the problem.

Remove fuel pump from tank ford windstar 98


To gain access to the fuel pump, it is necessary to remove the fuel tank.
  1. Depressurize the fuel system and remove the fuel tank from the vehicle.
  2. Remove any dirt that has accumulated around the fuel pump module attaching flange, to prevent it from entering the tank during service.
  3. Turn the fuel pump module locking ring counterclockwise using a locking ring removal tool or a brass drift and remove the locking ring.
  4. Remove the fuel pump module.
  5. Remove the seal gasket and discard it.

To install:
  1. Put a light coating of grease on a new seal ring to hold it in place during assembly. Install it in fuel tank ring groove.
  2. Insert the fuel pump module into the fuel tank, then secure it in place with the locking ring. Tighten the ring until secure.
  3. Install the tank in the vehicle.
  4. Install a minimum of 10 gallons of fuel and check for leaks.
  5. Install a pressure gauge on the throttle body valve and turn the ignition ON for 3 seconds. Turn the key OFF , then repeat the key cycle five to ten times until the pressure gauge shows at least 30 psi.
  6. Check for fuel leaks at the fittings.
  7. Remove the pressure gauge.
  8. Start the engine and check for fuel leaks.

2 issues.\1st is the truck has dual fuel tanks and


The only way the empty tank could leak is that the switch that controls the two tanks is pumping fuel into your empty tank. This is a common problem with the Ford trucks. In fact Ford had a recall on these to replace the switch for this very problem.
Problem 2: The F-250 you have probably has a full floating axle in it. Remove the wheel. Remove the brake drum. Remove the 8 bolts on the end of the axle stub. Remove the axle. Then you will need to remove the large axle lock nut and the lock ring under it. Then remove one more axle nut. Carefully remove the hub and dont let the outer bearing drop to the floor as it might damage it. Flip the hub over and remove the old wheel seal. Check the bearings. If o.k. put them back in the hub. Install the new wheel seal. Then reverse the disassembly procedure to place it all back together. When finished refill the differential. And be sure to clean the oil from the brake drum and replace the brake shoes if they are contaminated so badly that you can't get them clean again. No special tools needed. Just a good all around assortment to accomplish this task. If you need to purchase tools it would be a good investment anyway. Tools never go out of style. They have uses over and over and pretty much pay for themself.
