Your car is fuel injected and the system has residual pressure, even when the engine is off. You … didn't ask but it is recommended that you change the transmission fluid yearly. If your car has never had the belt replaced it needs it now because regardless of miles, 10 years is about the limit. The gas cools the pump and if run dry it could have burned up. When that filter gets to be a restriction, the pump suffers and has to work increasingly harder.
Fortunately, changing your Impreza's fuel pump is a very simple task following these steps. Still on the first filter after 123,000 miles, and going strong. Undo this clip and the rest is intuitive. The system should now be bled ready for the car to start. I replaced my spark plugs, which was a vain effort though probably about time to, anyway. Because of the lighting patterns of composite headlamps, you could drive for a long time and not realize that you have only one headlamp.
Put the new filter in place don't clamp it yet and attach the two hoses, slide the clamps up and tighten them back down. Clean fuel is essential to an engine because large particles can sometimes be in the gasoline. You may see it as a bit of loss of perormance, you may not, but over time a filter will clog. I think it is the same for a fuel pump. It is right behind the windshield washer fluid tank. Also to sometimes hold those additional hoses you removed from the guide out of the way and to offer words of encouragement, and to admire you afterward. You explanation intuitively makes sense, but is not entirely correct.
Unlike a carb, most fuel injection systems pump the gas through a regulator and back to the tank, so the pump cycles the gas constantly. There is an access door next to the lever, but it looks pretty small to be of much help. If you drive in dusty or sandy conditions, you should change your filter more frequently. Though I do not recall servicing this exact vehicle model my experience with previous subaru's is that the fuel filter is located in the engine compartment on the battery side, close to the firewall and beneath the brake master cylinder. If you know that the pump is bad I can give you instructions on changing it.
As you start to get crud accumulating in the filter the pressure required to push the gas through the filter increases. I've underlined and numbered three passages in your post. I opened the gas cap to release the pressure, then stuffed packing paper around the filter to catch the bit of gas that leaked out of the hoses. In tank fuel filters should not be confused with fuel pump strainers. America under-hood, the fuel filter is pressurized, so protecting your eyes, with a cold engine, and a rag to soak up the fuel, disconnect the fuel lines, unclip from the bracket, and remove.
It's best to rotate the hose back and forth around the filters pipe to break it loose, then pull it off. I'm no fuel pump expert, but I have some doubts about each of these statements. So it's most unlikely but possible. Look for the fuel line coming from the fuel tank and you … should find the filter. If the fuel filter was changed recently, clear the codes and test drive the vehicle. There is a short period of time when the vehicle is first started, after the filter has been changed, when the cylinders may not get the fuel charge they should.
Cheers mate, take care and Safe Travels! Check with the transmission hot, idling in Park. One tube lets fuel in to be filtered and the other lets it back into the main fuel line that goes to the engine. You will see a domed cover held on by 4 screws. This directly effects the fuel volume and pressure as it's mostly being pissed back into the tank instead of downstream to the engine. I would imagin my filter is just discusting I've owned my subie for 10months and I've got 100,000k on it. You will need to pop those hoses out of the guide, but then you can wait till you have removed the old filter to pop that guide off of it and transfer it to the new filter. It's tuff to get at if that is where it is.
Turn the key on so the fuel pump will come on and fill and pressurize the system. It's around the outside of the body of the filter and lifts up and away to un-clip. Undo the bolts, and the filter is in there After replacement bleed the system by squeezing the rubber bul … b located in the fuel line on the left hand side of the engine squeeze until positive pressure is felt in the bulb. While the gas station tanks are much better these days, there is still a certain amount of crud in their tanks and eventually in yours. Thanks so much, the end of this month I plan on doing this as part of my winter prep, and I'm totally new to subarus so this is gonna help a ton. I would also check the connector for the fuel pump on top of the sender unit before trying to get to the relay. If the fuel filter is in line you will stumble across it at some point.
