The fuel filter is located under the car
The fuel filter on an 82 Old Royale is located under the car. More specifically, it is situated under the rear of the car, in front of the fuel tank. It is placed towards the front/center on the passenger's side frame rail, about 18 inches from the passenger-side rear tire.
To replace the fuel filter, you will need to raise the car on a hoist and disconnect the fuel lines from the filter using a back-up wrench to prevent damage to the fuel lines. Before disconnecting the lines, remember to release the pressure on them. You can do this by loosening one line and wrapping a rag around it to soak up any escaping fuel. When you remove the lower line, the filter will be full of fuel, so be prepared to catch it with a container.
You will need a 10mm socket and ratchet to remove the old filter from its mount. To install the new filter, simply reverse the disassembly process. Make sure to check all lines and replace them if needed with SAE 30-R9 fuel injection fuel line.
It is important to note that you should not smoke while performing this task, as there may be escaping fuel vapors that could ignite.

It is in the rear third of the vehicle
The fuel filter on an 82 Old Royale is located in the rear third of the vehicle. This means that you will need to jack up the car to access it. The process of changing the fuel filter is relatively straightforward, but it is important to exercise caution when working with fuel.
Before beginning the process of changing the fuel filter, it is important to relieve the pressure from the lines. This can be done by loosening one of the lines and wrapping a rag around it to soak up any escaping fuel. It is also important to note that you should not smoke while performing this task.
Once the pressure has been released, you will need to remove the fuel filter from its mount using a 10mm socket and ratchet. The hardest part of the process is getting the line off of the fuel filter. This may take some time and effort due to the vacuum. A razor blade can be useful in removing the old hoses.
After the fuel filter has been removed, you will need to catch any remaining fuel that leaks out. Be sure to use a suitable container and dispose of the fuel properly. Install a new fuel filter and reconnect the lines, ensuring that all connections are secure.
Overall, changing the fuel filter on an 82 Old Royale is a manageable task, but it is important to take the necessary precautions when working with fuel and to be patient when dealing with the fuel lines and hoses.

You will need to relieve the pressure from the lines
To relieve the pressure from the fuel lines of your 1982 Oldsmobile 88 Royale, you will need to locate the Schrader valve on the fuel rail. The Schrader valve is similar to a bicycle tire valve and is typically found on the fuel rail closest to the passenger side of the car. It is usually covered by a small black plastic cap. Once you have located the Schrader valve, follow these steps:
- Place a shop towel or a rag under and around the Schrader valve to catch any dripping fuel.
- With the engine off, press a small screwdriver onto the Schrader valve until you no longer hear fuel dripping from the line. Be cautious, as a small amount of fuel may squirt out.
- Alternatively, you can turn the key in the ignition to the "Run" position without starting the engine. You should hear the fuel pump activate for about 3 seconds and then turn off.
- After releasing the pressure, you can proceed with removing the fuel filter. Be prepared to catch any remaining fuel when you remove the filter, as it may still drip.
It is important to relieve the pressure in the fuel lines before changing the fuel filter to avoid getting sprayed with fuel and to facilitate the removal of the fuel lines without causing damage.

The filter will be full of fuel, so wrap a rag around the line
The fuel filter on an 82 Olds Royale is located under the vehicle, towards the front/center on the passenger's side frame rail.
When changing the fuel filter, you will need to disconnect the fuel lines from the filter. The filter will be full of fuel, so wrap a rag around the line when twisting the first fuel line loose. This will prevent a liberal dousing of pressurized fuel and the tiny spurt of fuel will be absorbed by the rag.
Use a backup wrench to disconnect the fuel lines to prevent damage to the fuel lines. Loosen the hose clamps and slide up the lines a few inches to get them out of the way. The fuel lines will probably be stuck on there fairly tight, so use a rag to pad the pliers' jaws and break them loose.
Once the old filter is removed, put the new filter inside the bracket, but leave it loose so you can slide it around as needed. Then, swap over both lines and secure everything in place. Dirty fuel will be trapped inside the old filter for easy disposal. Before replacing the cover, test the new filter connections for leaks with at least twice the pressure found during road use.

A 10mm socket and ratchet are required to remove the filter
The fuel filter on an 82 Olds Royale is located under the vehicle, towards the front/center on the passenger's side frame rail.
When removing the fuel filter, it is important to use the correct tools to avoid damage to the vehicle and injury to yourself. A 10mm socket and ratchet are required to remove the filter. This size is suitable for most vehicles, including the 2006+ Saab models, which require simple hand tools for fuel pump replacement.
The 10mm socket will fit the fuel filter cap and allow you to loosen and remove it. Using a ratchet provides leverage and makes it easier to turn the socket and loosen tight caps. This combination of tools is also useful for other automotive tasks, such as removing fuel pump lock rings in some vehicles.
It is important to note that some fuel filters may have retainer clips that need to be carefully handled to avoid breakage. Additionally, when removing the fuel filter cap, it is recommended to avoid using anti-seize, as it may find its way into the fuel filter. Instead, consider lubricating the "O" ring.
