Replacing Fuel Pump 692026: Step-By-Step Guide For Your Briggs Engine

The Briggs & Stratton 692026 fuel pump is used to propel fuel from the gas tank into the engine. It is typically mounted on the carburettor, near the fuel tank, or between the tank and carburettor. If you are experiencing issues such as jerking or sputtering, or losing power when accelerating, your fuel pump may need replacing. The replacement part for the 692026 pump is the 799056, which has a round shape, as opposed to the rectangular shape of the 692026. This new shape may make it challenging to find a suitable mounting location. However, with some creativity and minor modifications, it is possible to install the replacement pump successfully.

Identify the location of the fuel pump

The fuel pump is located on the engine shroud and tucks behind the air cleaner assembly. The fuel pump is rectangular in shape and attaches to the motor shroud.

The replacement part is round and almost twice the size of the original fuel pump. The replacement part does not fit in the original spot and requires a longer fuel line. The mounting holes of the replacement part also do not match the original pump.

Check for hairline cracks and other damage

To check for hairline cracks and other damage, you'll need to perform a thorough inspection of the fuel pump. Here are some detailed steps to guide you through the process:

• Visual Inspection: Start by carefully examining the exterior of the fuel pump for any signs of damage. Hairline cracks, also known as craze lines, are typically superficial and affect the enamel or protective coating of the component. These cracks may be challenging to spot, so it's recommended to use a flashlight to enhance visibility. Shine the light directly on the fuel pump and look for any fine cracks or lines on its surface.
• Check for Leaks: During your visual inspection, pay close attention to any signs of leaks or fluid seepage. Even minor hairline cracks can lead to fluid leakage, so look for any wet spots, stains, or dripping fluids.
• Feel for Irregularities: Use your fingers to gently feel the surface of the fuel pump. Run your fingertips along the entire component, feeling for any irregularities, rough patches, or raised areas. Sometimes, hairline cracks can create a slightly raised edge or texture difference that can be detected by touch.
• Performance Indicators: Aside from visual and tactile inspections, consider the performance of the fuel pump. If you notice a sharp, stabbing pain when you bite down, this could indicate a hairline crack. Additionally, if the fuel pump is not functioning optimally, such as struggling to build pressure or exhibiting unusual noise, it could be a sign of damage.
• Comparison with a New Part: If possible, compare the suspected damaged fuel pump with a new, undamaged one. This side-by-side comparison can help you identify any deviations or discrepancies that may be indicative of hairline cracks or other damage.
• Use a Magnifying Glass: If you have access to a magnifying glass or a jeweler's loupe, use it to conduct a more detailed inspection. Magnification can help you detect even the finest hairline cracks that may not be visible to the naked eye.
• Consult a Professional: If you're unsure or unable to identify hairline cracks, don't hesitate to consult a small engine repair specialist or a Briggs and Stratton authorized service center. They have the expertise and equipment to thoroughly inspect the fuel pump and identify any signs of damage.

Remember, hairline cracks can develop due to various factors, including normal wear and tear, exposure to corrosive fluids, or mechanical stress. Therefore, it's essential to conduct regular inspections and address any damage promptly to ensure the proper functioning and longevity of the fuel pump.

Disconnect the fuel hoses

To disconnect the fuel hoses, you will need a pair of needle-nose pliers. This is to loosen the clips that hold the hoses in place.

Before disconnecting the hoses, ensure that you have turned off the fuel valve at the base of the tank, where the fuel line is attached. If your equipment does not have a fuel valve, you can stop the flow of gas by clamping the fuel line with a fuel line clamp.

Once the fuel supply is closed, you can then proceed to disconnect the fuel hoses using the needle-nose pliers. It is important to be cautious when performing this task, as you are working with flammable fuel. Ensure that you are in a well-ventilated area and take the necessary precautions to avoid any accidental ignition sources.

After disconnecting the hoses, you will need to remove the mounting screws and carefully disassemble the pump to access its internal components for further inspection and possible replacement.

Remove the screws and disassemble the pump

To remove the screws and disassemble the pump, follow these steps:

First, with the fuel valve closed or the line clamped, remove the mounting screws. You can do this by using a screwdriver to loosen the screws and then removing them by hand or with a screwdriver, depending on the type of screw head.

Next, disconnect the fuel hoses. Fuel hoses can usually be disconnected using needle-nose pliers to loosen the clips. Be careful not to damage the hoses as you disconnect them, as this could lead to fuel leaks.

Once the hoses are disconnected, you can remove the screws holding the pump together and carefully disassemble it. Take note of how the pump is assembled so that you can put it back together correctly if needed.

After disassembling the pump, inspect the body for any cracks or other damage. If there are any issues, the pump body may need to be replaced. Soaking metal parts in an all-purpose parts cleaner can help remove any built-up grime or debris.

Finally, check the hoses for any signs of wear or damage, such as cracks, softening, or hardening. Replace any faulty parts to ensure the pump functions correctly.

Remember to refer to the specific model of your Briggs and Stratton fuel pump when disassembling and reassembling, as there may be variations in the part configuration.

Reassemble the pump with a new gasket kit

To reassemble the pump with a new gasket kit, follow these steps:

Firstly, ensure you have the correct gasket kit for your Briggs and Stratton fuel pump. The gasket kit for the 692026 model is 393397. This kit includes two tiny springs and the large pump spring.

When reassembling, carefully handle the two small springs, as they are very delicate and can easily be lost or damaged. These springs sit on opposite sides of the diaphragm. You will see small posts that they sit on to locate them. The large spring should be placed towards the diaphragm.

Take care when sandwiching the pump together, ensuring that nothing falls out of position. You may wish to apply a small amount of grease to the springs to help keep them in place.

Finally, refer to a diagram or manual to ensure all parts are correctly positioned and secured before operating your equipment.
