FAQ
Q1: Is this pump a direct fit for my Perkins 1104 engine?
This pump (294050-0521) is commonly used in Perkins 1100 series engines. However, due to variations in engine configurations and fuel system setups, we strongly recommend comparing the pump’s mounting flange, connector type, and part number with your original unit before purchase. If you are unsure, please contact us with your engine serial number for verification.
Q2: What is the difference between a remanufactured and a new injection pump?
A remanufactured pump is a used core that has been completely disassembled, cleaned, inspected, and rebuilt with new or reconditioned components to meet original equipment specifications. It offers the same level of performance and reliability as a new unit but at a significantly lower cost. Our remanufactured pumps are 100% tested to ensure they function like new.
Q3: What should I do if the pump fails to start the engine after installation?
First, ensure the pump is correctly timed with the engine and that the fuel lines are primed and free of air. Check that the electrical connections to the pump’s solenoid are secure. If the issue persists, it is recommended to have a professional diesel mechanic inspect the installation. If the pump is found to be faulty, please contact us immediately to initiate a warranty claim.
