The fuel filter in a Chevrolet S10 pickup truck is located in the engine compartment, mounted in the fuel line in front of the carburetor. The exact location of the fuel filter depends on the model year and engine configuration of the S10. For example, for the 1991 Chevrolet S10 with a 2.8L V6 engine, the fuel filter is located in the engine compartment, directly below the power steering pump. It is a challenging location to access. Some S10 models may have two fuel filters, with the second one located on the lower frame rail under the bed of the truck. When replacing the fuel filter, it is important to relieve the pressure in the fuel system and to use the appropriate tools and safety precautions.

Fuel filter location in 1982 S10 v6 2.8L
The fuel filter on a 1982 S10 V6 2.8L pickup is located where the fuel line enters the carburettor. It is situated in the engine compartment, directly underneath the power steering pump.
To replace the fuel filter, you will need to purchase a new fuel filter, anti-seize, a rag, a pan or shallow bucket, and proper wrenches. You may also need a small flathead screwdriver and penetrating oil. It is recommended to drive the truck up on ramps or jack it up and safely secure it with properly rated jack stands. The fuel system is always pressurised, so you must relieve the pressure. This can be done by pulling the fuel pump relay (or fuse), which is located in the glovebox or under the hood. Once it's pulled, turn the key to the run position, and you should not hear the fuel pump prime.
When you have relieved the pressure, unbolt the fuel lines slowly. It is recommended to place a rag over the area to prevent spraying and catch any fuel that drains. There is one bolt that secures the filter to the frame.
To install the new fuel filter, follow the reverse process of removal. Use anti-seize on the line threads and where the nuts rotate on the lines. Plug the relays back in (or fuse), and turn the key to the run position. Do not start the engine. You should hear the fuel pump prime. Once this is done, check to make sure there are no leaks. If there are no leaks, start the truck and let it run to ensure there are no leaks. If there are no leaks, you are done.

Tools required to replace the fuel filter
The fuel filter on an S10 pickup is usually located in the engine compartment, either by the brake master cylinder or just below and behind the power steering pump. However, some models have the fuel filter located under the truck, ahead of the fuel tank, attached to the inner side of the frame rail.
Now, to replace the fuel filter on an S10 pickup, you will need the following tools:
- Fuel filter
- Anti-seize or waterproof grease
- Rag
- Pan or shallow bucket
- Proper wrenches, including a line wrench or a flare end wrench
- Small flathead screwdriver
- Penetrating oil
- Jack and jack stands (if the truck is lowered)
It is important to relieve the pressure in the fuel system before starting the replacement process. This can be done by pulling the fuel pump relay or fuse and turning the key to the "run" position. Once the pressure is released, you can proceed with replacing the fuel filter.
Additionally, some GM vehicles require special tools to release the fuel lines, so it is recommended to refer to the specific make and model of your S10 pickup for exact tool requirements.

Steps to replace the fuel filter
Firstly, ensure you have all the necessary equipment. This includes a fuel filter, anti-seize, a rag, a pan or shallow bucket, proper wrenches, and a small flathead screwdriver. You may also need penetrating oil, jack stands, and a jack or ramp, depending on the height of your truck.
Secondly, relieve the pressure in the fuel system. This can be done by pulling the fuel pump relay or fuse. The relay is typically located in the glove box or under the hood. Once pulled, turn the key to the run position and ensure you do not hear the fuel pump prime, which sounds like a whine or hiss.
Thirdly, remove the old fuel filter. This may involve crawling under the truck and using wrenches to loosen the filter connections. Be cautious, as there may still be pressure in the lines. It is recommended to use a line wrench or a well-fitting regular wrench.
Fourthly, install the new fuel filter. Follow the direction of flow marked on the filter or in the filter directions. Use anti-seize on the line threads and where the nuts rotate on the lines to prevent rusting and make future replacements easier.
Finally, plug the relays back in and turn the key to the run position without starting the engine. Listen for the fuel pump prime and check for any leaks. If there are no leaks, start the truck and let it run for a while to ensure there are no issues.
Please note that these steps are based on guidance for a 1995 2.2L S10 truck, and the process may vary slightly for different models or years of the S10 pickup. Always exercise caution when working on a vehicle, especially when dealing with the fuel system, as there is a risk of fire.

Relieving pressure from the fuel system
The fuel filter on an S10 pickup is located in different places depending on the model of the vehicle. For a 1991 Chevrolet S10 pickup, the 2.5/151 4-cylinder fuel filter is located under the hood/engine compartment by the brake master cylinder. The 2.8/173 6-cylinder fuel filter is located under the hood/engine compartment on the driver's side, following the fuel line from the throttle body along the front of the engine, just below and behind the power steering pump. The 4.3/262 6-cylinder fuel filter is located under the truck, ahead of the fuel tank, attached to the inner side of the frame rail.
Now, to relieve pressure from the fuel system of an S10 pickup, there are several methods that can be employed. Here is a step-by-step guide:
- Remove the gas cap: This is a simple method that can help relieve some pressure.
- Turn the key to the "Run" position without starting the engine: This will activate the fuel pump and relieve some pressure. You should be able to hear the fuel pump whine for about 3 seconds.
- Locate the Schrader valve: The Schrader valve is located on the fuel rail, usually on the passenger side of the car. It is similar to a valve stem on a car tire and has a small black plastic cap. Unscrew the cap to expose the valve stem.
- Depress the valve stem: With the cap unscrewed, press down on the valve stem. This will release a small amount of fuel, so be cautious and do not perform this step while smoking.
- Use a bucket and loosen the fuel filter: Place a bucket under the fuel filter and loosen it to release the pressure. This method instantly relieves the pressure but can be messy.
- Remove the fuel pump relay or fuse: By pulling the fuel pump relay or removing the fuse, you can relieve pressure. Turn the key to the "Run" position, and you should not hear the fuel pump prime (a whining or hissing noise).
- Start the engine and let it run out of gas: This method involves starting the engine and removing the fuel pump relay or fuse. The engine will run until it stalls due to a lack of fuel. Be cautious, as this method can result in fuel spillage.
It is important to note that some people suggest not worrying about the pressure, as the volume is not significant. However, it is always recommended to take precautions and relieve the pressure before performing any maintenance or repairs on the fuel system. Additionally, make sure to have rags or absorbent materials handy to soak up any fuel drips or spills.
