Typically, a carbureted engine does not require a fuel return line. In most carbureted systems, fuel is delivered from the tank via a mechanical pump mounted on the engine, which pumps fuel directly to the carburetor. The design is relatively simple: fuel is drawn as needed, depending on throttle input, with excess staying in the float bowls of the carburetor. However, there are exceptions where a return line might be beneficial or needed. For instance, in high-performance applications or where vapor lock is a concern, a fuel return line can help by circulating excess fuel back to the tank, thereby cooling the fuel supply and reducing the chance of vapor lock by lessening the time fuel spends in the heat of the engine bay.

If necessary, raise the front end using a jack and secure it safely on stands or ramps. 3. Put on your gloves and safety glasses for protection. 4. Under the vehicle, locate the oil drain plug. This is usually on the bottom of the engine oil pan. 5. Place the oil drain pan under the drain plug. 6. Use your wrench to loosen and remove the drain plug, allowing the oil to drain into the pan. Be cautious as the oil may be hot. 7. While the oil is draining, remove the old oil filter using the oil filter wrench. Some oil will likely come out here too, so have your drain pan handy. 8....
