Fuel filter replacement method is as follows: 1. Remove the vehicle key and disconnect the fuel pump fuse or power supply. 2. Remove the rear seat cushion and the cover on the fuel pump. 3. After removing the retaining ring, the fuel pump assembly can be taken out. 4. Replace the corresponding parts of the old fuel filter with the new fuel filter assembly. More information about the Highlander is as follows: 1. The Highlander features a stylish and noble appearance, elegant and grand. Triangular headlights, a hexagonal front grille design, integrated Toyota emblem, thick chrome decorations, fog lights embedded with chrome accents, and a slightly forward-leaning front design give the entire front face a fashionable and three-dimensional look. 2. The interior design of the Highlander is simple and elegant, with numerous buttons on the center console, but the layout is reasonable and operation is convenient.
Back when I was learning car repair from my master in the workshop, replacing the gasoline filter required locating it first. Typically, the filter is installed near the chassis or fuel tank, so you need to lift the car with a hoist. Before starting, you must disconnect the battery's negative terminal and remove the fuel pump fuse to let the engine shut down and release pressure. Otherwise, gasoline might spray out when disconnecting the fuel lines, which is extremely dangerous. Prepare the new filter and wrenches, and pay special attention to the direction of the fuel lines when removing the old part—mark them with a pen. The arrow on the new filter must align with the fuel flow direction, and the clips must make a 'click' sound to confirm they're locked. After finishing, check for leaks and avoid reinstalling the interior trim panel for a couple of days to monitor the situation, as gasoline leaks are no joke. This job takes about two hours if you do it yourself, and safety measures must not be skipped.
Last time at the repair shop, I watched the mechanic replace the fuel filter. The procedure was actually quite standardized. First, they connected the car to a diagnostic scanner to check fuel pressure data, ensuring complete system pressure release. When locating the filter, special tools were required to disconnect the quick-release couplings - regular wrenches could easily damage the plastic clips. During removal of the old filter, oil-absorbent pads were placed underneath to prevent gasoline from dripping onto the exhaust pipe. Before installing the new filter, a thin layer of engine oil was applied to the sealing ring for better airtightness. Finally, after starting the engine for inspection, the mechanic specifically asked me to squat nearby and check for gasoline odor, saying this was the most direct inspection method. The entire process took only about half an hour, but it couldn't be done properly without a vehicle lift.
