Step 1: Locate the Fuel Filter
1. Open the hood of your 1997 Toyota 4Runner.
2. Locate the fuel filter. It's usually found on the driver's side of the engine compartment, near the rear of the engine.
3. The fuel filter is a cylindrical-shaped component with two fuel lines connected to it.
Step 2: Relieve Fuel Pressure
1. Before removing the fuel filter, you must relieve the fuel pressure in the fuel line to prevent fuel from spraying out.
2. To do this, locate the Schrader valve on the fuel injector rail.
3. Use a flat-head screwdriver to depress the valve for a few seconds to release the fuel pressure.
Step 3: Disconnect the Fuel Lines
1. Once the fuel pressure is relieved, use a wrench to loosen and disconnect the fuel lines from the fuel filter.
2. Be careful, as there may be some residual fuel in the lines that can spill out.
3. Have some rags ready to catch any spilled fuel.
Step 4: Remove the Fuel Filter
1. Unscrew the fuel filter from the mounting bracket using a wrench.
2. Be careful not to drop the fuel filter, as it may still contain some fuel.
Step 5: Install the New Fuel Filter
1. Screw the new fuel filter onto the mounting bracket until it's snug.
2. Hand-tighten the fuel filter first, then use a wrench to tighten it further.
Step 6: Reconnect the Fuel Lines
1. Reconnect the fuel lines to the fuel filter.
2. Use a wrench to tighten the fuel line connections until they are snug.
Step 7: Start the Engine
1. Once the new fuel filter is installed and the fuel lines are reconnected, start the engine.
2. Let the engine run for a few minutes to check for any leaks or issues.
NOTE: After changing the fuel filter, it's recommended to drive your 1997 Toyota 4Runner for a short distance to allow the fuel system to circulate and adjust to the new filter.
