FAQ

Q1: How do I confirm this part is compatible with my specific fuel pump?
A1: Always match the part number stamped on your original component. The primary numbers for this unit are 7139-235C and 7139235C. For critical applications, consult your pump’s service manual or provide the pump model and engine details to our technical team for verification.

Q2: What is the importance of the high-speed steel material?
A2: High-speed steel is essential for the rotor’s durability. It maintains its hardness and shape at the high temperatures and extreme pressures generated inside the fuel pump, preventing premature wear, scoring, and loss of injection pressure which leads to poor engine performance.

Q3: What is your process for international B2B orders and shipping?
A3: We specialize in B2B transactions. Process: 1) Receive your PO. 2) Provide a proforma invoice. 3) Arrange secure payment. 4) Package according to your requirements. 5) Ship via your chosen carrier with full tracking and documentation (commercial invoice, packing list, certificate of origin).
