  Q: How to handle the fuel tank when removing and installing the fuel pump and sending unit assembly on Volvo 740?

  A:

  On all vehicles, there's the fuel tank, which has the Fuel Pump and sending unit assembly. To remove and install, disconnect the negative battery cable and properly relieve the fuel system pressure. For vehicles with the 2.9L 6 cylinder engine or 2.3 and 2.4L 5 cylinder engine, tilt the rear seat forward and remove or fold back the trunk compartment carpet over the right hand wheel well panel, disconnect the fuel pump electrical connections taking note of the color markings on the hoses. Detach the quick-connect couplers for the fuel delivery and return hoses, raise and safely support the vehicle on jack stands, and fully drain the fuel tank, making sure that a dry-chemical fire extinguisher is handy in case of an explosion because of the explosive nature of fuel vapors. At the trunk, remove the panels over the filler hose and it may be necessary to remove the spare tire on some vehicles. Roll back the carpet and take off the access panel cover, disconnect the fuel filler pipe connection and take off the circlip holding the fuel filler pipe if fitted. At the fuel tank, label and disconnect all fuel lines to the tank, all electrical connectors to the tank. On some models it may be necessary to remove the driveshaft. Position a floor jack beneath the tank using a large piece of wood as a cushion, raise the jack until it just touches the tank and then remove any shields or protective covers on the tank. Loosen and remove the tank retaining bolts, lower the jack slowly and check for any obstructions. For installation, lift the fuel tank to the correct position, install and tighten attaching bolts, remove the floor jack, fasten the electrical connections making sure they are in the right position, install the protective panel in the trunk, replace the spare tire if necessary and the carpet. Finally, drop the vehicle, connect the negative battery cable, start the ignition key ON and look for the leaks.
