Failure Symptoms

Initial signs of failure may include a slight hesitation during acceleration or a noticeable drop in engine RPM under load. If left unaddressed, fuel delivery inconsistencies will worsen, leading to progressively more severe power loss and potential stalling. Continued operation with a failing component risks uneven combustion and increased stress on other engine systems.

Installation Tip

Ensure the fuel system is properly purged of air before installation to prevent starting issues. Avoid overtightening connections, as this can damage the component or fuel lines.

Service Note

Inspect and replace fuel filters and fuel lines concurrently with this component to ensure optimal fuel system performance.
