            Fuel Accumulator Products

            Are you familiar with the fuel accumulator? This isn't a much mentioned part of the fuel system, but it helps in maintaining good residual pressure in the assembly. The accumulator is a simple chamber with a diaphragm and spring. As fuel flows through, the diaphragm extends against the spring. When the engine stops, the pressure of the spring against the diaphragm, and therefore the fuel, ensures that the residual pressure is kept. This is important to make re-starting efficient and to eliminate the problems that usually occur upon engine switch off-the heating of the fuel lines caused by the increase of temperature under the hood. Other than this function, the fuel accumulator also reduces the fuel pump noise as the engine runs, all while ensuring that the fuel flow is smooth. While this component is helpful, it can also cause problems when it is damaged. If its diaphragm is ruptured, you will experience driving problems caused by fuel pressure loss. Don't put up with the problem and replace a damaged fuel accumulator at once. Check out your needed replacement here at Auto Parts Warehouse! Our wide selection of parts will help you with all your needs, whether for replacement or upgrade.

            How to Find a Good Fuel Accumulator

            Fuel from the tank doesn't flow straight to your engine in a snap. It streams to different fuel system parts to control the flow. Some of these parts work under high pressure to maintain smooth process from one part to the next. A key component in the chain is the fuel accumulator.

            Read on to know the function of a fuel accumulator, and discover some useful hints if you need to replace your stock part.

            Select the exact type of fuel accumulator

            Almost all fuel accumulators are designed the same way; they are built with 2 chambers inside a cylindrical housing divided by a diaphragm. But if you want to be sure that you'll get the right one, the best advice is to look for the specific type for your car's make, year, and model. Aftermarket websites provide good quality replacements. All you have to do is key-in the details to find the specific type of replacement that is fit for your car.

            Since fuel hoses are connected to and from the fuel accumulator, it is important to check if it fits correct and tight. This will determine if leaking may occur overtime, that's why you have to check it before you purchase.

            A fuel accumulator that fits your budget

            You can find a cheap one around $78, and that price is already from a good brand. The regular price of a fuel accumulator is around $100-$200. However, if you want to get a premium quality, you will need to put out around $400 for that one. You should always look for the trusted because they offer the best quality and value for your money. They also provide limited warranty for their products.

            A helpful buying tip

            • All vehicles that have "Continuous Injection System" or CIS use a fuel accumulator, and it's not a rare car part.

            How to Safely Replace Your Fuel Accumulator

            The fuel from the gas tank that flow to your car engine must have no unnecessary restrictions. Otherwise, the engine will receive inadequate fuel amount and might not start properly. If you keep on cranking the ignition switch, it will only worsen the situation. This fuel accumulator replacement guide will show you how you solve this problem in just ten easy steps.

            Difficulty level: Moderate

            Tools checklist:

            • Jack
            • Jack stand
            • Wrench
            • Ratchet
            • Screwdriver
            • Pliers
            • Socket with extension

            Step 1: Park the car on a clean, level surface and engage the parking brake.

            Step 2: Lift the rear of the car until you have space to work comfortably. Place the jack stands underneath the car's solid frame.

            Step 3: Locate the fuel filter's metal line and remove it using a wrench. Watch out for fuel leaking when removing the metal line.

            Step 4: Check the current fuel accumulator located across the fuel filter. The accumulator is held by a retaining strap. Unbolt the strap using the socket with extension arm. Pull the accumulator loose and you will see there are pressure lines attached to it and some insulators as well.

            Step 5: Disconnect the current fuel accumulator from the pressure lines. Beware; fuel might spray while performing this. Remove the fittings on the accumulator because it will be attached to the new one.

            Step 6: Take the new fuel accumulator and attach the fittings and the insulators from the old one.

            Step 7: Place the new filter in place of the old one and reconnect the pressure lines. Reattach the metal line from the fuel filter as well but don't tighten the connection yet.

            Step 8: Reattach the retaining straps and begin to tighten the fuel lines afterwards.

            Step 9: Disengage the vehicle from the jack stand.

            Step 10: Turn on the engine and check for any fuel leaks. Make the adjustments if necessary.
