If you are looking to purge your 2003 Malibu boat fuel tank, there are a few things to consider. Firstly, it is important to determine the exact location of the fuel tank and its components. The EVAP purge vent and solenoid are typically located under the vehicle, near the fuel tank, while the purge solenoid is usually found on top of the engine, close to the firewall. Additionally, there may be a second assembly with multiple fuel lines that need to be addressed. When replacing the fuel tank, it is recommended to consult a professional or refer to a repair manual for detailed instructions specific to your boat model. Safety precautions and proper disposal of old fuel should also be taken into account.

What You'll Learn
The location of the EVAP purge vent
The EVAP purge vent location depends on the make and model of the vehicle.
For a 2008 Chevrolet Malibu LS, the EVAP purge vent is located under the vehicle, towards the back, by the fuel tank. It is a small box with two hoses attached to it. The purge solenoid is on top of the engine, near the firewall, and the vent solenoid is on top of the fuel tank.
For a 2006 Chevrolet Malibu, the EVAP purge vent is on top of the gas tank.
For a 2014 Honda CR-V, the EVAP canister is on the left (driver's side) under the driver's door.
For a 2018 Honda CR-V, the EVAP canister purge valve is located on the engine.
For a 2017/2018 Traverse, the EVAP purge valve is on the right side of the engine up front.
If you are having trouble locating the EVAP purge vent, you can try following the hoses from the intake manifold until you locate the purge valve. It is also recommended to consult a professional if you are unsure about what you are doing.

How to remove the fuel tank
To remove the fuel from a 2003 Malibu boat fuel tank, it is important to first run the boat to reduce the fuel level. A fuel level of less than 1/8 of a tank is ideal before draining. If your boat is on a trailer, you can use the fuel line to your engine to siphon the fuel out. Place an empty gas tank on the ground next to the boat, remove the engine connector fitting from the hose, and insert the hose into the empty tank. Then, pump the primer bulb to start the siphoning process and allow the tank to drain.
Alternatively, you can use a manual or electric fuel pump to remove the fuel. Manual pumps are cheaper and typically sold as kits at local marina stores. Electric pumps are more efficient but pricier, ranging from $150 to $300. If you are using a manual pump, submerge the suction pump in the gas tank and ensure that it is attached to a hose that can reach the bottom of the tank.
Another option is to remove the fuel sending unit on the top of the tank and pump the fuel out from there. You can also disconnect the outlet of the fuel primer bulb from the outboard motor and attach a long hose to the bulb's outlet, placing the other end into a suitable container on the ground. Pump the bulb to siphon the fuel out until the tank is empty.
It is important to note that you should always wear safety gear and ensure your boat is in a dry, well-ventilated place when draining the fuel tank. Additionally, you may want to run a few gallons of fresh gas through the tank after it seems empty to flush out any remaining water or sediment.

Replacing the fuel pump
First, you need to gain access to the fuel pump. This may be possible by lifting the carpet in the trunk or under the back seat. If not, you will need to remove the fuel tank. Make sure you have the vehicle high enough to be able to remove the tank safely. It is important to drain the tank before removing it to avoid spills.
Once you have access to the fuel pump, you will need to remove it from the tank. The fuel pump is usually held in place by a lock ring at the top of the tank. Be careful when handling the fuel pump, as it is made of plastic and can break easily.
Next, you will need to acquire a replacement fuel pump. It is recommended to use a dealer part or an OEM part from a reputable source. Ensure that the replacement pump is compatible with your boat's fuel tank.
After obtaining the correct replacement pump, you can install it in the fuel tank. Make sure to refer to the manufacturer's instructions for proper installation.
Finally, check for proper function by testing the fuel pump. Ensure that there is fuel in the tank and that the pump is receiving power. If the pump is not functioning properly, double-check your connections and refer to the troubleshooting steps provided by the manufacturer.
It is important to note that replacing the fuel pump may not always fix the issue. There could be other underlying problems with the fuel system or engine that require professional diagnosis and repair.

The vent solenoid
In terms of function, the solenoid commonly used on boats consists of wire wrapped around a metal cylinder with a metal piston inside. When electricity is introduced to the wire wrappings, they become magnetized, pulling the piston into the solenoid and overcoming the spring that usually holds the piston partially out of the cylinder. This action allows the solenoid to act as a valve, controlling the flow of fuel.
If there is an issue with the vent solenoid, it may be necessary to replace it. This process typically costs between $150 and $320 for the part and labor. It is also important to note that some solenoids cannot be serviced and must be replaced.
