Does my 1974 dodge dart with a 318 motor have a fuel return line on it fuel sending unit?

Hey Jim,I see that it is showing 2 types at auto part stores.You can see the return line on the one with it,the way to find out is when you change you will see.Not good to buy in advance,may have to order.
  1. Usually a pump with a return will have a separate connection to go from the pump back to the cell. If yours has that connection ,I would put the return line back to the cell on it.
    A return line is nothing more than excess fuel being returned to the cell.

How much to replace a fuel pump in 97 buick lesabre

The fuel pump is inside the fuel tank. To replace it you must remove the fuel lines, fill and vent hoses, and the electrical connector at the fuel tank. Then the two straps holding the tank in place must be released and the tank will come down. A lock ring holds the sending unit and fuel pump in place and must be removed by sliding it counterclockwise, then the sending unit and pump will come out as an assembly. Often the sending unit lines are too corroded to be reused, or are too corroded to release the fuel lines. In that case I cut the steel lines at the sending unit with side cutters, which allows me to take the lines down and position them where I can pick the rust out from the connector sockets and, eventually unlock the fuel lines. The sending unit must be replaced; and I just order complete assemblies ready to drop into the tank. You'll also want to replace the o-rings on the fuel lines.

Fual tank removel

This task is not so easy for a do it yourselfer. This car must be raised on a hoist, then wiring,fuel lines have to be disconnected, and fuel in the tank must be drained or recovered. . Then the tank straps have to be removed. With the tank supported it can now be removed.
Don`t try this at home !!! Take vehicle to a repair shop- labour to remove and reinstall should be about $200 - without parts or further repairs-example fuel lines..

How do you replace a GMC Yukon Denali fuel pump? And where is it located on the Denali?

Fuel Pump
Removal & Installation
To Remove:

  1. Remove the fuel tank.
  2. Disconnect the fuel lines.
  3. Using the J 45722 or equivalent, remove the sending unit lock ring.


  4. Remove the sending unit and seal.
  5. Discard the seal.
    Drain the fuel from the fuel sender assembly
    into an approved container in order to reduce the risk of fire and personal
    injury. Never store the fuel in an open container.

  6. Clean sealing surfaces.

To Install:

In order to reduce the risk of fire and
personal injury that may result from a fuel leak, always replace the fuel sender
gasket when reinstalling the fuel sender assembly.

  1. Install a NEW seal.
    The fuel pump strainer must be in a
    horizontal position when the sending unit is installed in the tank. When
    installing the sending unit, assure that the fuel pump strainer does not block
    full travel of the float arm.

  2. Install the sending unit into the fuel tank.
  3. Using J 45722 or equivalent, install the sending unit lock ring.
  4. Connect the fuel lines to the sending unit.
  5. Install the fuel tank.

1989 Saab 900 low level fuel light

You don;t say whether the fuel gauge is reading accurately, or whether it's always on empty. If the gauge is always showing empty, it's most likely a problem with the sending unit in the fuel tank. Check the resistance across the two terminals of the sending unit.

On a C900, the fuel sender level unit is separate from the fuel pump and located on the right side top of the tank, accessible by removing the trunk floor lift up panel (the pump is located on the left side top of the tank.
Possible problems are: electrical line off or broken, float not working (it's fairly delicate); or gauge not working.

Test the resistance of the sending unit with the lines disconnected, the resistance should be 2.6 to 3.8 ohms full tank, 63.3 to 67.5 ohms empty tank; and test for voltage across the top of the sender unit, if no voltage, that's likely the problem!

If the gauge is otherwise reading accurately (showing 'full' for a full tank, etc) then the problem is likely a gauge malfunction and can be simply replaced.

Good luck!
