What You'll Learn
Fuel line maintenance
The fuel line is a vital part of your 50cc scooter, delivering fuel from the fuel tank to the engine to ensure smooth running. They are usually made of plastic or rubber, but can also be made of other materials.
Fuel lines are also known as fuel hoses and are typically located between the gas tank and the carburetor. In-line fuel filters are often placed in the fuel line to prevent sediment from clogging the carburetor. Clear fuel lines can be useful to easily identify when gas is or is not flowing to the carburetor.
To maintain the fuel line, it is important to keep it clean and free of debris. This can be done by regularly cleaning the line with a degreaser and air hose. Dirty fuel can cause the scooter to run poorly and can even be harmful to your health if inhaled.
Before starting any maintenance on the fuel line, it is important to first remove the cover over the engine, then unscrew and remove the fuel pump. It is also good practice to use a funnel to pour out any old gasoline and replace it with fresh gas. Always be sure to follow the manufacturer's instructions for replacing the fuel line.

Fuel tank removal
First, park the scooter on a level surface and engage the centre stand. Unlock the seat and raise it into a fully opened position. Remove any screws or fasteners from the bottom of the under-seat storage compartment, using a screwdriver or a ratchet. Pull the seat and the attached storage compartment out of the scooter.
Next, remove the side body panels from the scooter, again using a screwdriver or a ratchet. This will give you access to the fuel tank and its connections. Turn the fuel valve to the "off" position. If your scooter has an automatic fuel valve, you may need to pull the vacuum hose off the fuel valve instead.
Now, you can start to disconnect the fuel tank from the scooter's frame. Unbolt the fuel tank using a ratchet. Loosen the clamp attaching the fuel hose to the fuel tank valve with a screwdriver, and then pull the hose off the valve outlet using pliers. Cover the fuel valve outlet with a shop towel to prevent any fuel leakage.
At this point, you can carefully lift the fuel tank off the scooter. Before removing it completely, remember to unscrew the fuel tank cap and drain the remaining fuel into a gas can or suitable container. You can do this by turning the fuel valve to the "on" position, or by connecting the valve's vacuum outlet to a vacuum source if your scooter has an automatic fuel valve.
Once the fuel tank is drained, you can inspect it for any signs of damage, such as corrosion, pinholes, or cracks. Check the fuel valve mating surface as well, as damage here could allow fuel to leak out. If the tank is damaged, you may need to repair or replace it.
Finally, if your scooter requires a new fuel tank, be sure to follow the manufacturer's instructions for installation. Reinstall the fuel tank onto the scooter, reconnecting the fuel and vacuum hoses to the fuel valve. Ensure all connections are secure before turning the fuel valve back on and refilling the tank.

Engine cover removal
To hook up the fuel lines on a 50cc scooter, you will first need to remove the engine cover. Here is a step-by-step guide on how to do this:
Step 1: Locate the Engine Cover
Find the engine cover by looking for a panel that covers the engine block. It is usually located near the carburetor and may be secured with screws or bolts.
Step 2: Gather the Necessary Tools
Before you begin, make sure you have the right tools for the job. You will likely need a socket wrench set with sockets ranging from 8mm to 14mm, as well as pliers.
Step 3: Remove Any Obstructions
If the engine cover is difficult to access, you may need to remove other components, such as the air filter box, to get a clear path to the cover. Make sure to keep track of any screws or bolts removed during this process.
Step 4: Unscrew and Remove the Engine Cover
Using your socket wrench, carefully unscrew any screws or bolts holding the engine cover in place. Some engine covers may also have clips or other fasteners that need to be released. Once all the fasteners have been removed, carefully lift and remove the engine cover, placing it aside in a safe place.
Step 5: Proceed with Caution
With the engine cover removed, you will now have access to the internal components of your scooter, including the fuel lines. It is important to exercise caution and follow the manufacturer's instructions when working on your scooter to avoid damage or injury.
By following these steps, you should now have access to the fuel lines and be able to proceed with hooking them up according to the specific instructions for your scooter model. Remember to consult a professional mechanic if you are unsure about any part of the process.

To begin, ensure your scooter is turned off. Then, disconnect the battery to prevent any electrical issues or mishaps during the removal process. This is an important safety precaution.
Step 2: Locate and Access the Fuel Pump
The fuel pump is typically located near or attached to the fuel tank on your scooter. Using a screwdriver or wrench, carefully remove the cover of the fuel pump to access it.
Step 3: Disconnect Fuel Lines and Electrical Connections
Before removing the fuel pump, you must disconnect the fuel lines and electrical connections attached to it. These connections facilitate the flow of fuel and power to the pump, so it is important to carefully detach them.
Step 4: Remove the Fuel Pump
Using the appropriate tools, carefully detach the fuel pump from its mounting position. Be gentle and take note of how the pump is secured in place, as you will need to install the new fuel pump in the same way.
Step 5: Install the New Fuel Pump
Obtain a new fuel pump and install it in the same position as the previous one. Ensure that it is securely attached and fastened correctly.
Step 6: Reconnect Fuel Lines and Electrical Connections
Reconnect the fuel lines and electrical connections to the new fuel pump. Double-check that all connections are secure and properly fitted to avoid any leaks or electrical issues.
Step 7: Reconnect the Battery and Test the New Fuel Pump
Once everything is securely connected, reconnect the battery. Start the scooter's engine to test the new fuel pump's functionality. Ensure that the scooter starts smoothly and that there are no leaks or unusual noises coming from the fuel pump area.
It is important to consult a professional mechanic or your scooter's manual if you are unsure about any steps in the removal or replacement process. Additionally, regular inspection, maintenance, and cleaning of your fuel pump system will help keep your scooter running smoothly and efficiently.
