FAQ

Q1: How do I confirm this sensor is compatible with my excavator’s engine?
A1: The surest method is to match the part number. Locate the existing fuel pressure sensor on your engine and verify its stamped part number matches 499000-6121 or 4990006121. Consult your equipment’s service manual for the correct part reference.

Q2: What is the typical cause of failure for this sensor, and how will a replacement improve performance?
A2> Common failures include internal circuit damage from voltage spikes or seal degradation leading to inaccurate readings. Replacing a faulty sensor restores precise fuel rail pressure data to the Engine Control Unit (ECU), resolving issues like power loss, poor fuel economy, hard starting, and excessive smoke.

Q3: What is your Minimum Order Quantity (MOQ) and can you support larger project requirements?
A3: Our standard MOQ is 4 pieces. We specialize in supporting B2B clients and can accommodate bulk orders for fleet maintenance, dealerships, or distribution. Contact us directly for volume pricing and customized logistics solutions.
