$29.99

Fits select 2011-2016 Chevrolet Silverado and GMC Sierra 2500/3500 HD (LML Duramax).
The Fleece Performance Return Fuel Pressure Test Port is a critical diagnostic tool for the LML Duramax platform. Designed to assist technicians and truck owners in troubleshooting the fuel system, this port is especially valuable when diagnosing potential CP4 high-pressure pump failures. When installed in the return fuel system, it provides a dedicated point to connect a pressure gauge and monitor return-side fuel pressure under operating conditions.
By allowing for precise pressure measurements, this component helps identify fuel restrictions or pump wear before they result in major engine damage. It is a direct-fit solution that integrates seamlessly into the factory return lines for a reliable seal during testing.
- Facilitates accurate return fuel pressure diagnostics
- Essential for monitoring CP4 pump health and system performance
- Installs directly into the return fuel side for gauge connection
- Specifically engineered for LML Duramax 6.6L engines
- Manufacturer Part Number: FPE-FPTP-GM-1116
