What It Is Used For

• Restoring fuel pressure when the engine cranks but does not receive adequate fuel
• Correcting hard-start or no-start conditions tied to weak in-tank pump output
• Replacing a faulty fuel level sender that causes inaccurate gauge readings
• Addressing fuel starvation, hesitation, or stalling caused by pump wear
• Replacing a leaking or deteriorated module seal during tank service

Installation Notes and Tips

Fits 2003 Hummer H2, N/A. Clean the fuel tank before installing the fuel pump to help prevent future seal problems.
