Fuel not getting to fuel tank - 1989 Ford Econoline

no year, huh? some years have a check valve , there,....
this forum is for usa cars, is car USA car?
the tanks just dont like siphoning. (check valve)
the FSM covers this , in the fuel section under bad pump.
1998 to 2006, ill guess, 06

i have the FSM and does not cover. bad fuel, no drain plug.

it shows how to get fuel lower, in filler neck
the tank has check valve at it its metal neck.
so inserting a hose in filler, will hit this check valve.
and all you get out , is 1/2 fuel.
id use the tank out procedure.
then empty all fuel, after step 5.
quote:

1. Disconnect the negative battery cable.
2. Relieve fuel pressure in fuel feed line.
3. Due to absence of fuel tank drain plug, drain fuel tank by pumping fuel out through fuel tank filler.
4. Use hand operated pump device to drain fuel tank.
5. Remove fuel tank.

tip tank to drain the remainder. out

here is one more way. (IDEA!)
do 1-4
then tip car to left. Jacks then stands at frame.
then remove the filler hose on tank
remove that pesky check valve. from neck last.

and pump out the rest.

It's inside the fuel tank. Access is on top. Remove tank. 2 straps hold it in place.

Removal

1. Relieve fuel system pressure as described under Fuel System Pressure Relief.
   

1. Drain fuel from the fuel tank as described.
   

1. Raise vehicle on hoist.
   

1. Remove the exhaust system as required. Refer to Section 09-00.
   

1. NOTE: The connections for the rear fuel supply return and vapor tube (9S278) to the fuel pump module are on top of the fuel tank and are inaccessible. They must be disconnected with the fuel tank partially lowered from the vehicle.
   
   Disconnect fuel tank to filler pipe hose (9047) and vent hoses connecting the fuel tank filler pipe (9034) to fuel tank. Disconnect one end of the vapor crossover hose at the rear over the driveshaft (4602).
   

1. Place a safety support under the fuel tank. Remove the bolts from the fuel tank support straps (9092). Take care not to deform the fuel tank or fuel tank support straps. Fuel tank capacity and/or fuel pick-up may be adversely affected.
   

1. Partially remove the fuel tank and disconnect the rear fuel supply return and vapor tubes at push connect fittings using Fuel Line Disconnect Tool Set T90T-9550-S. Disconnect electrical connector from the fuel pump module.
   

1. Remove fuel tank from the vehicle.
   

Hi, the fuel pump is located in the fuel tank and to get to it you have to lower the fuel tank from the car, make sure you have used all the fuel up as it will be to heavy to handle if the fuel is left in it,
you need to make sure the car is high enough off the floor to get the fuel tank lowered enough to get the tank lowered.

if your doing this yourself then make sure you have some good axle stands to put the car on before you do any work under neath,

check under the back seat to see if their is an access panel to the tank but im pretty sure their isnt check first just in case im wrong but from what i remember you need to lower the tank down to get to the pump.

FUEL PUMP IN FUEL TANK.YOU HAVE TO REMOVE GAS FROM FUEL TANK THEN REMOVE GAS TANK TO GET PUMP OUT.

Below are the proper steps to removing your vehicle's fuel tank..



Disconnect the negative battery cable.
Relieve the fuel pressure
Remove the rear seat cushion.
Remove the plastic grommet from the floor pan.
Detach the fuel pump electrical harness.
Disconnect the fuel lines from the fuel pump by compressing the tabs on both sides of each nylon push connect fitting and easing the fuel line off of the fuel pump.
Raise and safely support the vehicle securely on jackstands.
Remove the muffler mount.
Remove the heat shields.
Remove the fuel tank cover.
Remove the drain plug and drain the gasoline into a approved container.
Disconnect the fuel lines and remove the fuel filter and base.
Loosen the fuel tank filler pipe clamp at the fuel tank.
Support the fuel tank using a hydraulic jack and a block of wood or other suitable device.
Remove the two fuel tank support strap bolts and position the straps out of the way.
Partially lower the fuel tank to access the fuel tank filler pipe vent tube and disconnect the vent tube and filler pipe from the tank.
Disconnect the fuel vapor tube from the tank.
Lower the tank from the vehicle.
Installation is the reverse of the removal procedure.

I believe this is a manual fuel pump and you may have lost the prime, no fuel in hose to tank. If the hose from rear frame to tank has a break or hole, it will **** air and not fuel from tank. If this is not the case, possible clogged fuel hose, tubing, or pickup tube in tank assuming you have turned the engine over serveral times and there is enough fuel in tank. Some tanks do not pickup from very bottom because of water laying in bottom of tank from condensation.

1. Properly relieve the fuel system pressure.
   
2. Drain the fuel tank.
   
3. Support the fuel tank.
   

1. Remove or disconnect the following:
2. Negative battery cable
   

• Filler neck from the tank
  
• Shield from tank and tank straps
  
• Fuel lines and vapor hose from pump
  
• Electrical connection from fuel pump
  
• Fuel tank
  
• Fuel pump/sending unit assembly by turning the locking ring (located on top of the fuel tank) counterclockwise using a spanner wrench
  
• Fuel pump from the fuel lever sending device
  

To install:
Install or connect the following:

• Fuel pump in tank with new seal around opening
  

NOTE The fuel pump strainer must be in a horizontal position when the fuel sender is installed in the tank. When installing the sender assembly, make sure that the fuel pump strainer does not block full travel of the float arm.

• Tank and connect fuel lines and vapor hose
  
• Tank to the frame. Torque the fasteners to 33 ft. lbs. (45 Nm).
  
• Shield
  
• Fuel filler neck and clamp
  
• Negative battery cable
  

1. Refill the tank.
   
2. Run the engine and check for leaks.

ok i'm going to guess that you have a gasoline engine with a side tank like in a pickup truck. if you have a diesel let me know, things might be a little different. here's the step by step for a gas side tank. before you start, disconnect the battery negative cable.
1. drain the fuel from the tank (they don't tell you how, just get as much out as you can)
2.raise and safely support vehicle (get it high enough that you can get under it to work on it)
3.loosen the fuel neck hose at fuel neck and disconnect filler neck from tank
4.support tank and remove tank support straps and insulator strips
5.remove frame mounted bracket
6.lower fuel tank shield
7.lower fuel tank enough to gain access to fuel and electrical connections
8.disconnect fuel feed and vapor hoses
9.disconnect electrical connectors
10.remove fuel sender assembly and seal ring
now to install new tank
1.install NEW seal ring and install sender
2.raise tank enough to connect fuel feed /vapor hoses and electrical connector
3.raise tank fully
4.install fuel tank shield
5.connect fuel tank filler neck and tighten clamp
CAUTION tighten fuel strap fasteners in steps, alternating between straps, until proper torque is reached. failure to properly follow this step can cause bottom of tank to deform. fuel gauge may read improper level if this occurs
6.install fuel tank brackets and insulator strips
torque nuts to 115 in-lbs
7.install fuel tank filler cap
8.connect battery negative cable
9.turn ignition switch off and on and check for leaks
it's pretty much the same for rear tank, just different location, may have off-road shield in back and torque spec is 47 ft-lbs, not 115 in-lbs. you still have to alternate when you torque straps or you risk deforming tank. hope that helps

I have never seen a fuel filter in the gas tank, fuel pump yes. To get to anything in the tank the tank has to be removed from the vehicle.

you have a tank switching valve under the truck that may be bad,also check the fuel lines coming out of the tank they could be cracked and sucking air instead of fuel
