Parts Required:

Fuel filter

Hot Tip:

Relieve fuel pressure before beginning

Performance Gain:

Restore good fuel flow

Complementary Modification:

Replace fuel pump

In modern Volvo automobiles the fuel pump is electric and located inside the fuel tank. The fuel pump creates positive pressure in the fuel lines, pushing gasoline to the fuel rail, where the engine control module controls flow to the engine via a programmed fuel injection map. In tank fuel pumps have many benefits. The fuel is submerged in fuel keeping it cool, preventing vapor lock and electrical issues. The fuel pump delivers a constant flow of gasoline to the fuel rail at a regulated pressure and volume. The fuel pump draws fuel from the fuel tank and pushes it through the fuel filter, mounted outside of the fuel tank.

A dirty or restricted fuel filter can cause poor engine performance and hard starting problems. If you suspect this is your issue you should replace your fuel filter.

Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

It is best to replace your fuel filter with the fuel pressure relieved. This reduces the amount of possible spilled fuel and fuel vapors. When replacing, work in a well-ventilated area. Working outdoors is a good choice. Do not use incandescent work lights or power tools. Fuel and fuel vapors are highly combustible. To relieve fuel pressure, remove the fuel pressure test cap and activate the Schrader valve. See our tech article on fuel pump replacing.

The fuel filter (red arrow) is mounted to the right of the muffler (green arrow) and next to the charcoal canister.

Start by cleaning the threads on the fuel filter clap fastener (red arrow).
Figure 2

Start by cleaning the threads on the fuel filter clap fastener (red arrow). Then apply a penetrating oil to the fastener. Let it sit for 10 minutes. Then remove it using a 12 or 23mm socket.

Next, check that the clamp (red arrow) is free and the filter can move back and forth.

Place a drain pan (green arrow) under the fuel filter.
Figure 4

Place a drain pan (green arrow) under the fuel filter. The front fitting (red arrow) points down and will leak fuel when the line is removed.

Push the fuel line toward the filter and hold it (green arrow).
Figure 5

Push the fuel line toward the filter and hold it (green arrow). Then using a trim panel tool push the fuel line collar toward the fuel line (red arrow). This action releases the friction style fuel line clamp. While holding the fuel line end in with the trim panel tool, slide the fuel line off the filter.

Now remove the rear fuel line the same way you did the front (red arrow).
Figure 6

Now remove the rear fuel line the same way you did the front (red arrow).

Pull the fuel line (red arrow) away from the fuel filter and allow the remaining fuel to drain into the drain pan.
Figure 7

Pull the fuel line (red arrow) away from the fuel filter and allow the remaining fuel to drain into the drain pan.

Slide the fuel filter out of the clamp to remove it.
Figure 8

Slide the fuel filter out of the clamp to remove it. Be careful as any excess fuel will spill out. When installing the new filter, be sure the arrows (green arrow) point toward the front of the vehicle.

Once the fuel filter is installed into the clamp, press the fuel lines onto the fuel filter (red arrow) until they stop.
Figure 9

Once the fuel filter is installed into the clamp, press the fuel lines onto the fuel filter (red arrow) until they stop. Center the fuel filter in the clamp and tighten it. Check for fuel leaks and wipe up any spilled fuel.
