Toyota 4Runner 1996-2002: How to Replace Fuel Filter
The fuel filter in the Toyota 4Runner should be replaced as a maintenance item. Read on to learn how to replace it yourself.
This article applies to the Toyota 4Runner (1996-2002).
Although the fuel filter doesn't need to be replaced as often as some of your other filters, such as the air filter, you still need to replace it at some point. The more clogged the fuel filter gets, the worse your Toyota 4Runner will drive. The fuel filter is the gate between the fuel tank and the engine. It is designed to filter the fuel going to the engine. Overtime and if you've used a dirty batch of fuel, it could get clogged, thus decreasing the amount of fuel reaching the engine, which results in hesitation when stepping on the gas and sometimes your car may not even start if it's really clogged. If you think you're ready for a new fuel filter, read on to learn how to replace it yourself in the Toyota 4Runner.

Step 1 – Disconnect negative battery terminal
Disconnect the negative battery terminal, then wrap it in a towel to avoid any contact with metal. This should help relieve the fuel pump of pressure.
Step 2 – Remove fuel filter
Before removing the air filter, some forum enthusiasts like to remove the gas cap to depressurize the system. You should still expect some fuel leaking from the filter when you remove it. Locate the fuel filter under the driver's door, along the frame rail. Then, use your wrench to remove the two fuel line nuts on each side of the filter. Pull the lines off, then remove the two bolts holding the filter in place.
Step 3 – Install new filter
Make sure the new filter is facing the right way, similar to the old one. Then tighten the two bolts to hold it in place. Install the two lines, then tighten their nuts. Finally, close the gas cap and connect the negative battery terminal.
