The fuel filter’s sole job is filtering the fuel from the gas tank before it reaches the engine for combustion. Dirty fuel is the leading cause of fuel filter failure. As dirt builds up within the filter, it eventually clogs and won't allow gas to pass through. Volvo recommends changing the fuel filter every 60,000 miles. On the 1998 Volvo V70 Turbo, the fuel filter mounts under the car on the passenger side near the fuel tank, and it can be changed right at home in less than 30 minutes.

Instructions

  1. 1

    Raise the bonnet and locate the fuse centre at the top of the engine compartment on the driver’s side. Take the cover off, and remove the number two fuse on the bottom row with a pair of needle-nosed pliers. The fuse—marked with a small “2” by it—is the fuel pump fuse.

  2. 2

    Remove the gas cap then start the engine, allowing the car to run until the engine stalls. Try to start the engine four additional times, waiting three seconds between attempts. If the car fails to start, that indicates the fuel pressure has been depleted.

  3. 3

    Loosen and remove the negative cable from the battery with a socket wrench.

  4. 4

    Raise the car on the rear driver’s side, with a car jack just forward of the tire. Place a jack stand underneath the frame rail to the left of the car jack. Lift the jack stand’s support arm until it makes full contact with the frame rail then lock the support arm.

  5. 5

    Locate the fuel filter underneath the car near the fuel tank. The fuel filter is shaped like a small beer can.

  6. 6

    Clean the dirt off the fuel filter and both fuel lines with a shop rag to lessen the likelihood of dirt getting into the fuel lines once they’ve been removed.

  7. 7

    Position a metal catch pan under the fuel filter, and remove the right fuel line first. The quick-connect fitting can be removed with a 17mm line wrench. Place the wrench between the quick-connect fitting and the fuel filter. Press down on the top of the quick-connect fitting while pulling it off the fuel filter. Repeat the same process to remove the fuel line on the left.

  8. 8

    Remove the bolt from the retaining clip securing the fuel filter to the frame with a socket wrench. Slide the old fuel filter out of the clip, and then install the new fuel filter in the retaining clip. Reinstall the retaining clip’s bolt and tighten the bolt until it is snug.

  9. 9

    Push the fuel lines back onto the new fuel filter. The quick-connect fittings will click into position. Check the fuel lines by pulling on them gently to make sure the quick-connect fittings engaged properly.

  10. 10

    Remove the jack stand and lower the car. Put the gas cap back on, and install the fuel pump fuse. Reconnect the negative cable securely to the battery. Turn the ignition forward to “on," and wait eight seconds before you start the engine. Check the repair area for leaks with the engine running. Shut the bonnet, and take the V70 for a test drive.

Tips and warnings

  • Starting the engine may take a few attempts. This is normal because of the low fuel pressure.
  • Do not leave the metal catch pan in direct sunlight even if has a small amount of fuel in it. Any gas that may have spilt on the ground should wiped up with a towel and disposed of properly. Never attempt to perform any repair to your car involving gasoline if you're in a closed-off environment. Gas fumes are very hazardous and highly combustible.
