Product Description
The Thermo King 11-4380 Elbow / Fuel Pump Fitting is a high-quality replacement component designed to provide a secure and leak-free connection between the fuel line and fuel pump in Thermo King refrigeration units. Manufactured with precision-machined brass or steel alloy, this fitting is engineered to withstand the demanding conditions of transport refrigeration systems, including constant vibration, pressure fluctuations, and exposure to fuel and refrigerants.
Its elbow-shaped design allows for efficient routing of fuel lines, minimizing stress on hoses and reducing the risk of kinks or leaks in tight installation spaces. Whether for routine maintenance or emergency repairs, the 11-4380 elbow fitting ensures optimal fuel delivery to maintain consistent engine performance and refrigeration efficiency. This makes it an essential part for Thermo King truck, trailer, and container refrigeration systems operating in long-haul or extreme temperature environments.
Product Advantages
-
Precision Fit and Compatibility – Direct replacement for Thermo King part number 11-4380, ensuring easy installation and perfect alignment with the fuel pump.
-
Leak-Proof Design – High-quality threads and sealing surfaces prevent fuel leakage under high pressure.
-
Durable Construction – Built from corrosion-resistant brass or steel to withstand exposure to diesel fuel and harsh operating conditions.
-
Efficient Fuel Flow – Smooth internal bore minimizes flow resistance, ensuring consistent fuel delivery to the pump.
-
Extended Service Life – Engineered to resist wear, vibration, and thermal expansion for long-lasting reliability.
Installation Instructions
-
Safety First – Turn off the refrigeration unit and disconnect the power supply. Allow the fuel system to depressurize before starting.
-
Remove Existing Fitting – Carefully detach the old elbow fitting from the fuel pump using an appropriate wrench. Check for any debris or damage on the connection threads.
-
Prepare the New Fitting – Inspect the new 11-4380 elbow for any shipping damage and apply a suitable thread sealant if required.
-
Install the New Elbow – Tighten the fitting securely to the fuel pump inlet, ensuring proper orientation of the elbow to prevent fuel line stress.
-
Reconnect Fuel Line – Attach the fuel line to the elbow and tighten clamps or fittings to create a leak-free connection.
-
System Check – Reconnect the power and test the refrigeration unit for proper fuel flow and absence of leaks.
Note: Installation should be performed by trained technicians to ensure compliance with Thermo King service standards.
