How to Extract Fuel from a Tank with a Filter Screen?
2 Answers
For vehicles with an intake injection fuel pressure regulator on the injector rail, remove the return pipe and connect a self-prepared hose from the rail's return pipe to a fuel bucket. Start the engine, and fuel will flow out through the hose. Below are relevant details: Rail Vehicles: For vehicles where the intake injection pressure regulator is not on the rail, you can remove the rail fuel pipe and connect a self-prepared hose using an appropriate hard pipe. Connect a wire from the battery's positive terminal to the fuel pump fuse, and fuel will flow out through the self-prepared hose. Direct Injection Vehicles: For direct injection vehicles, connect the self-prepared hose to the high-pressure fuel pump's inlet pipe and connect the fuel pump fuse or the fuel pump wiring (for models with a fuel pump module), and fuel will flow out. An 8mm horizontal hose can be used for the self-prepared hose, and an 8mm outer diameter iron pipe or hard plastic pipe can be used for connecting the hard pipe.
I frequently work on car maintenance, and it's quite common to encounter fuel tank screens when siphoning fuel. The screen is there to prevent dust and debris from entering the fuel line, so you mustn't damage it by force. From my experience, using a manual fuel siphon pump—like those made of plastic or metal—and slowly inserting the tube through the fuel filler neck works best. Before starting, ensure the engine is off, work in a well-ventilated area, and keep away from fire sources, as gasoline is highly flammable and dangerous. When siphoning, gently probe with the tube, avoiding direct contact with the screen. If the screen is too dense or awkwardly positioned, causing poor fuel flow, try alternative methods, such as checking if your car model has a dedicated siphon port or consulting professional tools. Safety is paramount—damaging the screen can lead to costly repairs and engine issues. I've tried this a few times myself: first, check the user manual to confirm the screen type, wear gloves for protection, and take it slow—you'll eventually get the fuel out. In short, DIY with caution, and if unsure, seek professional help to avoid making things worse.
