Your fuel accumulator is usually found right near the fuel pump in the engine bay, and often near the fuel filter. It is a cylindrical object with two housings inside it, with one for a diaphragm filling the entire circumference, and one for a heavy spring. You can usually find it easily by following the fuel lines, because it will have a fuel line on both ends and some will even have two lines on one end. Of course, finding it is important because it will eventually require replacement.

And it will require replacement because it is not designed to work forever and the components inside it will eventually wear out. The most common problem is the diaphragm, which can become torn either by the spring, or just through wear and tear, and this will cause a fuel leak so that the pressure in the lines cannot be maintained. The spring is also at great risk of wear and tear, because even a slight loosening in it over time will cause the same loss of pressure. Most problems will require the accumulator to be replaced completely, so you need to be on the lookout for certain symptoms.

Those symptoms include the engine being difficult to start when it is warm, because the fuel has all been allowed to go back to the fuel tank or, even worse, has been allowed to leak into the atmosphere. If the engine takes a long time to start when you have recently used it, then this is a good clue. You may also find that the engine runs roughly while cold because the accumulator is not smoothing out the flow of fuel, so your engine is not getting one constant flow, but a flow that stops and starts. Each problem will become worse as the accumulator breaks down further, so you should be investigating it at the first sign of trouble.

The fuel delivery system is a complex beast, and this is because it does more than simply supply fuel to the engine from the fuel tank. It also performs a number of tasks that are designed to help the engine with efficient running, and to help get more power from it, which means there are a number of parts involved. One of those parts is the fuel accumulator, which seems like a very boring part but is actually responsible for the smooth running of your vehicle!

    The importance of your fuel accumulator cannot be understated because it ensures your engine has a smooth supply of fuel. It achieves this by maintaining pressure in the fuel lines when you turn the engine off, so that for a period of time there will be fuel in the lines all the way up to the engine. While the engine is running, the accumulator helps to smooth out the way the fuel is moving, so your engine has a constant supply, rather than a stop and start supply.

      How To Replace Fuel Injectors
      Fuel injectors spray fuel directly into your engine’s cylinders during the intake stroke when a piston moves down to allow air and fuel to fill the cylinder chamber. When injectors are malfunctioning, leaking, or have failed completely, they will cause rough engine performance, poor idle, reduced power and economy, and exhaust that’s rich enough in unburned fuel to damage expensive exhaust parts such as oxygen sensors and catalytic converters.

    Great Deal!
    Product is a quality OEM Part with a direct fit. Installation was easy, and replacing this part solved my problem. Product was also priced very well, half the cost of local auto parts stores. Will be making more purchases from CARiD in the future.
