Loosen the fuel tank cap
To do this, locate the fuel tank cap on your 1987 Chevy Silverado. It is usually located on the driver's side of the vehicle, near the fuel filler door. Once you have located the fuel tank cap, use a wrench or a pair of pliers to loosen it. Turn it counterclockwise to loosen the cap. You may need to apply some force to loosen it, but be careful not to strip the threads or damage the cap.
Once the fuel tank cap is loosened, you should be able to relieve the vapour pressure in the fuel tank. You may hear a hissing sound as the pressure escapes, which is normal. Wait until the hissing sound stops and the pressure is fully relieved before proceeding to the next step.
Make sure to keep your face and body away from the fuel tank cap as you loosen it and relieve the pressure. This is a safety precaution to avoid any potential exposure to fuel vapours, which can be harmful. Always work in a well-ventilated area when performing maintenance on your vehicle's fuel system.

Remove the water-in-fuel sensor assembly
To remove the water-in-fuel sensor assembly, you will need a wrench, deep socket, or pliers. First, drain the remaining fuel out of the fuel filter and dispose of it. Then, with your chosen tool, remove the water-in-fuel sensor assembly from the bottom of the filter. If the water in the fuel sensor assembly is damaged, you will need to replace it with a new one. You cannot reuse it.

Lubricate the new gasket
Lubricating the new gasket is an important step when replacing the fuel filter of a 1987 Chevy Silverado. Before installing the new gasket, you should lubricate it with clean engine oil. This will ensure that the gasket is properly sealed and will prevent any leaks. It is important to note that you should not fill the new filter with fuel. Instead, you will prime it after installation.
To lubricate the new gasket, you can use a small amount of clean engine oil. Apply the oil to the surface of the gasket, ensuring that it is evenly distributed. You can use your finger or a small brush to spread the oil and make sure that the entire surface is coated. This will help to create a tight seal and prevent any leaks.
If the new fuel filter comes with an o-ring for the water-in-fuel sensor assembly, it is important to lubricate this as well. The o-ring should be lubricated with clean engine oil before installing it. This will help to ensure a proper seal and prevent any leaks in the sensor assembly.
By taking the time to properly lubricate the new gasket and o-ring, you can help ensure a successful fuel filter replacement. This will keep your Chevy Silverado running smoothly and prevent any potential issues caused by leaks or improper seals. Following these steps will help you maintain the performance and longevity of your vehicle.
