Replace the fuel filter that you think has not been replaced for a long time. The current mileage is 160,000 km. Before starting work, I removed the fuse just in case to release the fuel pressure. It is quicker to remove the intake pipe than to struggle in a small space. Place a waste cloth under the filter in case of gasoline overflow. The fuel filter used is Monotaro. Two copper washers are also included. First, loosen the flare nut on the lower side. A flare nut wrench of 14mm is required as it is fairly tight. Gasoline will leak, so tighten it lightly. After loosening the upper union bolt, loosen and remove it with 2 bolts and 1 nut on the bracket, 10 mm. It is easier to have a universal joint and a deep socket. The figure which removed the whole bracket. It smells so bad because it leaks a lot of gasoline. The plastic bracket to which the mysterious hose is connected has crumbled. Old and new fuel filters. I like black like genuine. Insert a new copper washer above and below the union bolt and tighten it tightly. Start the engine, check that there are no […]
Let’s replace consumables as much as possible for preventive maintenance. This is a new fuel filter. First, release the fuel pressure. Let’s remove the fuel cap. You should hear a “psss” sound when you remove it. If you don’t hear it, may have leaked pressure between the fill port and the tank. Next, release the fuel pressure from the fuel pump to the injector. The most common method is as follows.1. Pull out the fuel pump fuse.2. Remove the fuel pump relay.Then the pump will not turn, so if you start the engine in that state the fuel will not go to the injector and it will stall in a few seconds and the fuel pressure will release. But Figaro doesn’t work this way. About step 1,there is a fuse, but it also serves as a power supply for the engine ECU, so it is no good. As you can see, step 2 is troublesome because you have to remove the air cleaner, and there is a possibility that the outside coupler will crack due to aging. So there is the easiest way. Unplug the fuel pump coupler. The place is the coupler shown in the image that appears after […]
Replace 300ZX fuel filter to improve idling malfunction. Since it’s work on the fuel line, of course fire is strictly prohibited. This is the genuine fuel filter we were preparing. I also wanted to replace the hoses, but I couldn’t make it in time. First, work to reduce fuel pressure. Check the position of “FUEL PUMP” in the fuse box. Start the engine and remove the “FUEL PUMP” fuse that you just checked. It should stall after a while, if for some reason it didn’t stall, you must stop the engine. Remove the fuel cap. Then crank it several times. OK if the engine does not start. Remove the negative of the battery. Prepare a towel and aluminum vat and remove the filter. Fortunately, there was no struggle such as the hose not being pulled out as heard in the rumor, and it was not tough. The fuel was a little spilled, but it was okay. By the way, the fuel that came out of the filter. I could not disassemble the filter because there were no tools, but it may have been quite dirty. Installation complete. The material on the out side was different from the one that was […]
