What You'll Learn
2002 Pontiac Sunfire GT 2.4L Fuel Lines
The 2002 Pontiac Sunfire GT 2.4L Fuel Lines include:
- 1 supply line 3/8" (in 3 easy-to-install sections)
- 1 return line 5/16" (in 4 easy-to-install sections)
- 1 vapor line 5/16" (in 3 easy-to-install sections)
- 1 left rear brake line 1/4"
- 1 right rear brake line 1/4"
- 1 fuel filter
The lines are constructed from Galfan-coated steel tubing for rust protection and are CNC (Computer Numerically Controlled) bent for an easy and precise installation. The hoses meet or exceed applicable SAE specifications – SAE J30R7.
Before installing the brake lines, there is a shipping bend in one section of each brake line that needs to be removed. The two rear brake lines in this kit are also incomplete and need to be spliced onto the existing brake lines at the lower firewall. Here are the steps to do this:
- Place new brake lines next to the original brake lines while they are still on the vehicle. Mark where the cut is to be made using a handheld tube cutter. Try to stagger both cuts to allow room for unions.
- Use the two tube nuts supplied. They will be threaded into the ends of the bronze-coloured unions.
- Slide the tube nuts onto the original brake lines that you just cut, making sure the hex of the nut is facing up. Make a bubble flare for each brake line.
You can refer to the video on how to remove the shipping bends for further clarification.

2002 Pontiac Grand Prix GTP Fuel Line Set
The 2002 Pontiac Grand Prix GTP Fuel Line Set is made for 3.8L engines. The set includes:
- 1 supply line 3/8" (in 2 easy-to-install sections)
- 1 return line 5/16" (in two easy-to-install sections)
- 1 vapor line 5/16" (in two easy-to-install sections)
- Hoses for engine connection
- 2 unions
- 1 fuel filter
The lines are constructed from Galfan-coated steel tubing for rust protection and are CNC-bent for easy, precise installation. All hoses are made from stainless steel braided Teflon with OE-style fittings.
Before installing the fuel line, a shipping bend will need to be removed from the lines. The nylon line attached to the new vapor line is not a direct replacement. It is a section of nylon line that will splice to the original nylon line on the vehicle. On the opposite end of the original nylon line, there are connectors, which may be damaged during removal. Repair kits with new OEM connectors are available.

Installation instructions for fuel lines
Preparation:
Before beginning the installation, gather all the necessary tools and safety equipment, such as gloves and eye protection. Ensure you have the correct fuel line for your vehicle and that it is compatible with your fuel system.
Removal of Old Fuel Line:
If you are replacing an existing fuel line, start by safely removing the old one. Drain the fuel from the line and disconnect it from the fuel tank, engine, and any other components it is attached to. Be careful not to damage any surrounding parts or connections.
Installation of New Fuel Line:
- Positioning: Place the new fuel line along the path of the old one, ensuring it is routed correctly and securely attached to the relevant components.
- Connections: Securely connect the fuel line to the fuel tank, engine, and any necessary fittings or clamps. Ensure all connections are tight and secure to prevent leaks.
- Protection: Some fuel lines may require additional protection, such as coating or wrapping, to prevent damage or leaks.
- Testing: Once the new fuel line is installed, carefully inspect it for any signs of damage or leaks. Test the fuel system to ensure proper functioning before operating the vehicle.
Tricks and Tips:
- Greasing: Some installers suggest greasing the fuel line to ease the installation process and protect the line.
- String Trick: This involves using a string to help guide the fuel line into place without damaging it.
- Spring Method: A ballpoint pen spring or similar object can be stretched over the fuel line and twisted to help guide it into place.
- Taper Cut: Cutting a taper at the end of the fuel line can make it easier to insert, especially for plain hose-type lines.
- Dowel Rod: For molded fuel lines, wrapping the hose around a smooth dowel rod can provide leverage and ease the installation process.
- Screwdriver: For Stihl molded gas lines, a screwdriver can be used to work the line in from the top.
- Hemostats: Using large hemostats can help reach and manipulate the fuel line without causing damage.
- Angle Cut: Cutting the tubing at a 45-degree angle can facilitate pulling it through the gas tank pass-through.

Fuel filter location
The fuel filter location in a 2002 Pontiac is inside the fuel tank and is part of the fuel pump module. It is designed to be a lifetime filter, but if it clogs, the entire fuel pump module must be replaced.
The fuel filter is located on the supply line, which is 3/8" and comes in three easy-to-install sections. There is also a return line of 5/16" in four easy-to-install sections and a vapor line of the same width in three easy-to-install sections.
To access the fuel filter, first, release the fuel pressure by loosening the gas cap. Then, raise and support the car on jack stands. Next, squeeze the plastic tabs on the male end of the connector and pull the connector apart. Some models have two tabs, while others have one, and the fuel line is screwed into the other side. Now, remove the filter mounting bolt, unhook the tab from the frame, and remove the filter. When installing the new filter, ensure that the arrow is pointing towards the front of the engine. On the line with plastic tabs, push until you hear a click, then pull to ensure it is latched. Finally, tighten the gas cap.

Fuel supply system
The fuel supply system in a car is a critical component that delivers fuel from the tank to the engine. It comprises various parts, including the fuel tank, fuel lines, fuel pump, and fuel filter, all working together to ensure a steady flow of fuel to the engine for combustion. Let's delve into the specifics of the 2002 Pontiac GM's fuel supply system:
Fuel Tank
The fuel tank in a car is a secure container that stores the fuel required for the engine's operation. It is typically made of plastic and is not repairable; hence, a replacement is necessary if it sustains damage. The fuel tank in the 2002 Pontiac GM is located under the vehicle and can be accessed by raising the car and placing it on jack stands. Before removing the tank, it is essential to relieve the fuel system pressure and disconnect the negative battery terminal for safety.
Fuel Lines
Fuel lines are the pathways that transport fuel from the tank to the engine. They are constructed from Galfan-coated steel tubing, which provides rust protection. The 2002 Pontiac GM fuel line set typically includes a supply line, a return line, and a vapor line. These lines are designed with easy-to-install sections and original equipment end forms and fittings for precise installation.
Fuel Pump
The fuel pump plays a crucial role in delivering fuel from the tank to the engine. In the 2002 Pontiac GM, the fuel pump is located inside the fuel tank. Issues with the fuel pump can cause the car to struggle to start or experience intermittent dying, as reported by some owners of the 2002 Pontiac GM.
Fuel Filter
The fuel filter is responsible for removing contaminants from the fuel before it enters the engine. It ensures that clean fuel reaches the engine, preventing damage to critical components. The fuel filter is usually located along the fuel lines, and its replacement is recommended at regular intervals to maintain optimal fuel flow and engine performance.
Additional Components
The fuel supply system also includes various other components that facilitate the smooth operation of the fuel delivery process. These include brackets, bolts, screws, washers, and clips that secure the fuel lines and other fuel system components in place. Additionally, the system may incorporate a fuel pressure regulator to maintain the appropriate fuel pressure for the engine's optimal performance.
