FAQ

Q1: What is the 3/7R specification in the rotor head model?
A: The “3/7R” refers to the rotor’s geometric configuration—specifically, the number of plungers or delivery ports (3) and the rotation direction (R for right-hand). This ensures precise fuel distribution in DP200 pumps.

Q2: How do I verify if this rotor head fits my DP200 pump?
A: Compare your existing rotor head’s part number (e.g., 7185-906L) and physical dimensions. This unit is a direct OE replacement for the 7185-906L. For other DP200 variants, check the pump model and rotor type (3/7R) before purchasing.

Q3: What maintenance is recommended for this fuel pump rotor head?
A: Ensure the fuel system is clean before installation to prevent contamination. Use diesel fuel with proper lubrication properties. Regularly inspect the rotor for wear or scoring during pump overhauls. Replacement is typically recommended during major fuel pump servicing.
