Fuel starvation: The inline fuel pump is designed to work in conjunction with the in-tank fuel pump to ensure a steady and sufficient supply of fuel to the engine. When the in-tank fuel pump is not functioning, the inline pump may not be able to draw enough fuel from the tank, leading to fuel starvation and engine performance issues.
Overheating: The inline fuel pump relies on the fuel flow to keep it cool. Without the in-tank fuel pump providing a continuous flow of fuel, the inline pump can overheat and potentially fail.
Increased wear and tear: Running the vehicle solely on the inline fuel pump puts extra strain on the pump, causing it to work harder than intended. This can accelerate wear and tear, reducing the lifespan of the inline fuel pump.
Additionally, bypassing the in-tank fuel pump may affect the fuel pressure and delivery, which can impact the engine's performance, drivability, and fuel efficiency.
If the in-tank fuel pump has failed, it is recommended to replace it as soon as possible to ensure proper fuel delivery and optimal vehicle performance.
