The fuel filter on an 87 El Camino is likely located on the left side, inside the frame, just ahead of the left rear wheel. It is a metal can with an input and output line that threads into the can. Some El Caminos may require a removal tool to release the couplings in the lines on the filter, while older models may have inverted flare nuts or lines that can be removed with a 5/8 wrench. Additionally, there may be a clamp holding the filter to the frame.

What You'll Learn

The fuel filter is likely on the left side, inside the frame
The fuel filter on your 1987 El Camino is likely located on the left side, inside the frame, just ahead of the left rear wheel. This is a common location for the fuel filter on many vehicles, including the 1987 El Camino.
To access the fuel filter, you may need to remove a clamp that holds it in place. In some cases, a removal tool may be required to release the couplings in the lines on the filter. Older models may have inverted flare nuts or lines that can be removed with a 5/8" wrench.
It is important to note that the fuel line on your 1987 El Camino may be pressurised. Always take the necessary precautions when working on any fuel system, such as removing the gas cap and having a rag ready to absorb any excess gas.
To locate the fuel filter more specifically, you can follow the line from the TBI (Throttle Body Injection). This should lead you directly to the fuel filter. Additionally, the fuel filter is usually located on the frame rail just forward of the fuel tank, so you can start your search in that area.
By following these instructions and locating the fuel filter on the left side, inside the frame, you can proceed with any necessary maintenance or repairs on your 1987 El Camino's fuel system.

It's ahead of the left rear wheel
The fuel filter on your 87 El Camino is located on the left side, on the inside of the frame, just ahead of the left rear wheel.
To access the fuel filter, you will need to locate it and identify the type of couplings in the lines on the filter. Some El Caminos require a specialized removal tool to release these couplings, while older models may have inverted flare nuts or lines that can be removed with a 5/8" wrench. In some cases, there may also be a clamp holding the filter to the frame, which you will need to remove.
Once you have identified the type of couplings and any clamps, you can proceed to remove the fuel filter. It is recommended to have a rag ready to catch any excess gas that may spill during the removal process. Additionally, you may want to take off the gas cap beforehand to reduce the pressure in the fuel system.
After successfully removing the old fuel filter, you can install a new one. Ensure that you route the input and output lines properly into the new filter, threading them into the metal can. Tighten the connections securely, following the specific requirements of your model, and reattach any clamps or couplings that were previously holding the filter in place.
By following these steps and paying close attention to the specific requirements of your 87 El Camino, you should be able to successfully locate, access, and replace the fuel filter ahead of the left rear wheel.

Some require a removal tool to release couplings
The fuel filter on an 87 El Camino is likely on the left side, on the inside of the frame, just ahead of the left rear wheel. Some require a removal tool to release couplings in the lines on the filter. If you are unable to locate the fuel filter in this position, follow the line from the TBI to find it.
The removal tool will be needed to release the couplings in the lines on the filter. This is because some El Camino models have couplings that need to be released with a specific tool. The tool is designed to fit into the coupling and allow it to be released safely and without damage. Without the tool, it may be difficult or impossible to release the couplings, as they are designed to be secure and tight.
The tool required for this task is likely a specialty tool designed specifically for releasing fuel filter couplings. It may be a handheld tool with a specific shape or mechanism that fits into the coupling and allows for its release. Alternatively, it could be a tool that attaches to a drill or another power tool to provide the necessary force and precision to release the couplings safely.
Some older El Camino models may not require a removal tool for the fuel filter couplings. Instead, these older models may have inverted flare nuts or lines that can be removed with a standard wrench. A 5/8" wrench is typically needed for this task. Additionally, there may be a clamp holding the filter to the frame, which can also be removed with a wrench or similar tool.
When replacing the fuel filter on an 87 El Camino, it is important to take the gas cap off beforehand and have a rag ready to catch any excess gas that may spill. This process should be similar to that of the Camaro, as the two vehicles share certain characteristics. Overall, replacing the fuel filter on an 87 El Camino is a straightforward process that can be completed in a short amount of time with the correct tools and knowledge.

Older models have inverted flare nuts/lines
The 1987 El Camino is equipped with a fuel filter that is typically located on the left side of the vehicle, positioned on the inside of the frame, just ahead of the left rear wheel. For older El Camino models, the fuel filter is secured in place with inverted flare nuts and lines. These inverted flare nuts require a different approach for removal compared to newer models.
To access and remove the fuel filter on older El Camino models with inverted flare nuts, you will need a 5/8" wrench. Start by locating the fuel filter on the left side of the vehicle, as mentioned earlier. Place the wrench on the inverted flare nut and loosen it by turning it counterclockwise. Be gentle and apply firm but controlled force to avoid damaging the nut or stripping the threads. Once the nut is loosened, you can proceed to remove the fuel filter.
It's important to note that there might also be a clamp holding the filter to the frame. If this is the case, you will need to loosen and remove the clamp before you can take out the filter. Make sure you have a rag or towel handy to catch any excess gas that may spill during the removal process. Safety should always be a priority when working on your El Camino, so ensure you are in a well-ventilated area and take the necessary precautions to avoid any accidents.
After successfully removing the old fuel filter, it's crucial to install a new one properly. Position the new fuel filter in the same location, ensuring it is securely fastened in place. Tighten the inverted flare nut with your wrench, but be careful not to overtighten it. Reattach any clamps that were previously holding the filter in place. Finally, check for any leaks and ensure that the fuel filter is securely installed before starting your El Camino.
By following these steps, you can safely replace the fuel filter on older El Camino models with inverted flare nuts/lines. Remember to consult a professional mechanic or a trusted repair guide if you have any doubts or concerns during the process.

It's usually a metal can with input and output lines
The fuel filter on an 87 El Camino is usually a metal can with an input and output line that threads into the can. It is located on the frame rail just forward of the fuel tank. To access it, you will need to look on the left side, on the inside of the frame, just ahead of the left rear wheel.
Some El Caminos require a removal tool to release the couplings in the lines on the filter. Others, particularly older models, have inverted flare nuts and lines that can be removed with a 5/8" wrench. There may also be a clamp holding the filter to the frame.
If you cannot locate the fuel filter in this area, you can try following the line from the TBI to find it. Before beginning any work on the fuel filter, it is recommended to remove the gas cap and have a rag ready to absorb any excess gas.
It is worth noting that the fuel line on the 87 El Camino is pressurized, so it is important to exercise caution when working on the fuel filter to prevent any leaks or damage to the system.
