Flip the priming switch on and off a few times to build pressure and fill fuel lines
To prime your Carter electric fuel pump, you must first locate the priming switch. This switch is usually found directly on the pump or in close proximity to it. The priming switch allows you to manually activate the pump to prime the fuel system, ensuring that fuel flows properly from the tank to the engine's fuel rail and injectors.
Now, flip the priming switch on and off a few times. This action will activate the pump, allowing it to build pressure and fill the fuel lines with gasoline. Be cautious not to leave the switch in the "on" position for an extended period, as this can damage the pump or cause a surplus of fuel to flood the engine. By flipping the switch on and off, you are manually controlling the pump's operation, ensuring that the fuel lines are adequately pressurised and filled.
The process of flipping the priming switch a few times helps to remove air from the fuel lines. Fuel pumps are designed to pump liquid fuel, not air. If there is air in the lines, the pump may not be able to create sufficient pressure to deliver fuel to the engine, resulting in starting and running problems. By manually activating the pump through the priming switch, you are ensuring that the lines are filled with fuel, allowing for smooth engine operation.
It is important to be cautious and not overextend the duration of flipping the switch on and off. Overdoing this process can lead to potential issues. Leaving the switch "on" for too long can cause fuel to keep pumping into the lines, leading to over-pressurisation and, in some cases, a flooding of the engine with excess fuel. Similarly, flipping the switch too many times without giving the pump time to work can be counterproductive. A few flips of the switch, followed by a brief pause, should be sufficient to build the necessary pressure and fill the fuel lines.
After priming the fuel pump, carefully reconnect any components you may have disconnected during the process, such as the fuel pump access plate or fuel outlet line. Ensure all connections are secure to prevent fuel leaks. Priming your electric fuel pump is a straightforward but vital step in ensuring your vehicle's engine starts and runs smoothly.

Do not leave the switch on for too long, to avoid engine flooding or pump damage
Priming a Carter electric fuel pump is a simple but crucial step in ensuring your vehicle's engine starts and runs smoothly. The process involves removing air from the fuel lines and ensuring a continuous flow of fuel, as fuel pumps are designed to pump liquid fuel, not air.
To prime the pump, locate the priming switch, usually found directly on the pump or nearby. Flip this switch on and off a couple of times to manually activate the pump, allowing it to build pressure and fill the fuel lines with gasoline.
It is important not to leave the switch on for an extended period. Leaving the switch on for too long can lead to two main issues: engine flooding and pump damage.
Firstly, keeping the switch on for too long can cause a surplus of fuel to flood the engine. This is because the pump continues to draw fuel from the tank and send it to the engine, even though the lines are already filled. This surplus of fuel can lead to engine flooding, causing starting and running problems for your vehicle.
Secondly, leaving the switch on for an extended period can also damage the fuel pump itself. The pump may overheat due to continuous operation, leading to potential internal corrosion and failure. Electric fuel pumps are sensitive to marginal fuel and can fail if water is run through them, so it is important to be cautious and avoid potential pump damage.
To avoid these issues, simply flip the priming switch on and off a few times, just enough to prime the fuel system, and then carefully reconnect any disconnected components, ensuring all connections are secure to prevent fuel leaks. This process will ensure reliable starting and smooth engine operation for your vehicle.
