The pump on my car is capable of 60-65 psi but this pressure is present at the pump only if I pinch the fuel line downstream from the pump. If you have had this car for sometime and the cabin filter has not been changed it is probably very clogged up. I checked the fuel lines on top of the engine I do not see any wet areas. In order to gain access to it, you must remove a cover plate which is behind the pa … ssenger side rear seat. After you change the filter reconnect the pump and replace cover. This can potentially stress the pump a little bit.
It is not uncommon for fuel filters to be located in the fuel tank. Lotsa states here out west pump 10% gasohol. Follow the transmission oil lines and they will lead you to a removable kick panel on the drivers side. The pump on my car is capable of 60-65 psi but this pressure is present at the pump only if I pinch the fuel line downstream from the pump. It is a little hard to take out. The fuel pump on your Subaru Impreza needs little or no service at all.
For these reasons, I think that a dirty filter, by increasing the pressure at the pump, by creating a condition where the pump strains at lower revs, will make it run harder and hotter and shorten its life. They diagnosed rust in fuel system. Either way, please post back with numbers. So have a rag ready and protect your eyes. This can potentially stress the pump a little bit. As the filter is clogged more, the pressure at the pump may increase some, but the flow decreases a lot as the pressure regulator will bypass less gas to the tank. Jack You explanation intuitively makes sense, but is not entirely correct.
Just this week one of my co-workers was complaining that her car was sluggish and she brought it into the shop. Suggested replacing all steel fuel lines, fuel rail, fuel pump fuel filter. Make sure both front seats are moved all the way forward. Is this a pending problem? Auto trans, dipstick located at left rear of engine compartment, under the brake master cylinder, buried under one or more rubber heater hoses. Took to dealer, injector in cylinder 2 diagnosed as bad. If this is an answer to my post s , read again. Faulty auto parts can either decrease the driving quality or impair the overall efficiency of your car or truck, contributing to increased gasoline consumption, inferior overall performance, or greater exposure to unexpected automobile or component breakdown.
I think the filter on my '95 at 135,000 is original. You should change the filter on your Impreza at least once a year or every 20,000 miles, whichever comes first. For the same reason a moderately dirty filter will increase the pressure at the pump while maintaining a constant pressure at the injectors if the regulator is good. You may also find the nearest subaru dealers service or parts department able to assist you. Thanks for reading Justin Hello, This is a great blog. Do you wait until your air or oil filters are affecting performance to change them? On a fuel injected car you really should change it on a regular interval. I was wondering if you can help with what seems to be a common subaru problem.
Manual trans, dipstick is larger, and located on right side passenger side of engine compartment, behind engine, about halfway between rear e … dge of engine and the firewall. The plate is screwed on with four Phillips Head screws. Do a half turn on the three screws and pop the cover off. But I buy aftermarket O2 sensors General and air filter Canadian Tire. The fuel filter is the black can with rubber fuel lines connecting to it.
What can I do to prevent a re-occurrence? Many thanks Z Hello J. The dripping freeze has stopped but this cold weather thing is still going on. When that filter gets to be a restriction, the pump suffers and has to work increasingly harder. It is on the drivers side, front strut pillar. Found brown gunk in gas return line.
You might need a plair of battery pliers to get the fuel hoses to move before removing them. Take off the hoses from the 3 ports, remove the 10 bolts. I said the only benefit I could see to the in-tank filter was that it may filter the fuel before entering the pump and hence protect the pump from crud and grit. 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. With clean filters, pressure regulator relieves the exccessive pressure and bypasses a significant flow back to the tank. I have a '95 Impreza and as far as I know its in the same spot on all Impreza's until about '04 or '05.
