  Q: Where is the fuel filter located and how often should it be replaced on Volvo 780?

  A:

  The fuel filter is located underneath the vehicle near the fuel tank or the driver's side of the firewall and it is recommended to change the fuel filter every 60,000 miles (96,000 km) or immediately, if there are evidences of dirt in the fuel system. To start off, relieve the pressure on the fuel system and disconnect the negative battery cable. Raise and safely support the vehicle and remove the fuel filter cover, if equipped. Have a container to catch residual fuel when loosening the fuel lines. Put a suitable container in place and loosen the fuel filter connections. For vehicles having threaded type fittings, remove the lines from the filter with the correct size wrenches. If it has quick-connect fittings, use a 17mm wrench to push down on the retaining tab on the fitting and remove the line, repeat on the other line. Remove the clamp holding the fuel filter to the bracket. For installation purposes, transfer the bracket to the new filter, taking note of the direction on the fuel filter before installing it to the bracket. Connect the fuel lines to the filter, for threaded type fittings, install the lines, make sure to get the copper seals in the correct position, and fasten to the correct torque. For quick-connect fittings, push the fittings onto the ends of the filter until it is heard to click into place. Finally, install the fuel filter cover if equipped, lower the vehicle and reconnect the negative battery cable.
