What You'll Learn
Relieve fuel pressure before removing fuel lines
It is important to relieve the fuel pressure before removing the fuel lines. This is because the fuel is pressurized and will spray everywhere if you do not depressurize the hoses.
First, locate and remove the fuse or relay for your car's fuel pump. You can usually find the fuse box under the dashboard on the driver's side or in the engine compartment. The fuel pump fuse may be labelled. If not, you can refer to your car's manual.
Next, try starting your car. If it doesn't start or shuts off after a few seconds, you've successfully depressurized the fuel lines. If your car starts normally, you may have forgotten to remove the fuse, so turn off the engine and try again.
Now, disconnect the battery by removing the negative battery cable. This is an important safety precaution to prevent any accidental electrical shorts. Place a jack under the vehicle and secure it with jack stands.
Locate the existing fuel lines and fuel line connectors. Place a bucket or drain pan under the fuel line to catch any residual fuel. Use the appropriate wrench or fuel line disconnect tool to loosen the fittings. You can now remove the fuel lines for replacement or repair.
It is also recommended to replace the fuel filter, which may have become partially clogged with dirt or other contaminants. This will help ensure optimal fuel flow and engine performance.
If you are unsure about any of these steps, it is best to consult a professional mechanic or seek advice from a trusted source. Working with fuel lines can be dangerous if not done properly, so taking the necessary precautions is essential.

Use quick-connect tools to remove lines
To remove the fuel lines in your 2002 Honda Accord, you can use quick-connect tools. These are an inexpensive but worthwhile investment to make the job easier and safer.
Firstly, relieve the fuel pressure before removing the fuel lines. This is important because the fuel is pressurised and will spray if you do not depressurise the hoses. To do this, locate and remove the fuse or relay for the fuel pump, then try to start the car. If it won't start or shuts off, you've successfully depressurised the fuel lines.
Next, disconnect the battery by removing the negative battery cable. Lift the vehicle using a jack and secure it with jack stands. Locate the existing fuel lines and fuel line connectors. Place a bucket or drain pan under the fuel line to catch any spillages.
Now, use your quick-connect tools to remove the lines. If you're unsure how to use them, there are plenty of videos online that can show you how to use a plastic tool to separate the fitting.
Once the lines are removed, you can also take the opportunity to replace the fuel filter, which may have become partially clogged with dirt or other contaminants.

Clean the fuel injectors
To clean the fuel injectors of a 2002 Honda Accord, you will need to "Seafoam" your car. This process will remove carbon deposits from your throttle body, IACV, intake manifold, intake ports, piston tops, and exhaust ports. It will also clean out deposits from your gas tank and fuel lines, as well as cleaning your fuel injectors.
Firstly, gather your materials and tools. You will need 2 cans of Seafoam motor treatment (liquid), 1 can of Seafoam Deep Creep (spray), a funnel, pliers, a Phillips screwdriver, a 3/8" ratchet, a 3/8" ratchet extension, and a spark plug socket.
Next, pour 1 can of Seafoam into your gas tank and run it through a full tank of gas. Then, run 2/3 of a can of Seafoam through the brake booster vacuum line with the engine running. After that, pour 1/3 of a can of Seafoam into your crankcase and run the car for a few miles.
Now, pour 1-2 tablespoons of Seafoam into each cylinder through the spark plug hole and let it set for 15 minutes. Then, run the car for a few more miles.
The next step is to spray Seafoam Deep Creep through the throttle body and intake manifold.
Finally, change the spark plugs, fuel filter, and oil.
It is important to follow these directions closely to avoid any problems during the process. Additionally, it is recommended to work in a well-ventilated area to avoid breathing in too many gasoline fumes.

Replace the fuel filter
To replace the fuel filter of a 2002 Honda Accord, you will need to locate the fuel filter first. For a 2002 Honda Accord, the fuel filter is located on the rear of the engine, near the brake master cylinder.
Once you have located the fuel filter, use a 14 mm wrench to rotate the nut on the lower fuel line counterclockwise and loosen it. Place a fluid catch pan underneath to catch any spilled gas. After removing the nut, pull the lower fuel line off and set it aside. Then, use a 17 mm flare nut wrench to loosen the Banjo bolt on the upper fuel line. Again, rotate the wrench counterclockwise to loosen the bolt, and then remove the fuel line by hand.
Next, remove the 14 mm bolt from the bottom fuel line and the 17 mm Banjo bolt from the upper fuel line. Using a 10 mm flare nut wrench, unfasten the two bolts from the clamp that holds the fuel filter in place. Finally, remove the two 10 mm bolts from the fuel filter clamp.
You can now install the new fuel filter. Simply follow the steps above in reverse. It is recommended to replace the fuel filter when replacing the fuel lines, as the fuel filter may become partially clogged with dirt or other contaminants.

Use compression fittings for high-pressure lines
If you are replacing the fuel lines on your 2002 Honda Accord, it is important to know whether the line is on the high-pressure side or the return side. If it is on the high-pressure side, you can use compression fittings. Compression fittings are most often used when a pressure line attaches to an assembly. They are commonly found where the fluid in the line is under considerable pressure.
You can purchase compression fittings at your local auto parts store. You will then splice in a piece of plastic fuel line. Ensure that the line fits as snugly as possible and double-clamp it with hose clamps at each end.
Before removing the fuel lines, it is important to relieve the fuel pressure. This is because the fuel is pressurized and will spray everywhere if you do not depressurize the hoses. First, locate and remove the fuse or relay for your car's fuel pump. Then, try starting the car. If it won't start or shuts off after a few seconds, you have successfully depressurized the fuel lines.
Some of the tools you will need for this job include pliers, screwdrivers, vice grips, a socket set, a ratchet wrench, jack stands, shop rags, and nitrile gloves.
