Duramax LB7 Diesel Fuel Injector
The Duramax LB7 Diesel Fuel Injector is a direct replacement component designed for 2001 to 2004 GM 6.6L Duramax diesel engines. It is engineered to replicate the original flow rate of 180 to 190 mm³ per stroke at 1600 bar injection pressure, with a nozzle orifice diameter of 0.185 mm. The injector body is machined from high-tensile alloy steel and features a hardened needle valve with a precision-ground tip.
The injector uses a solenoid-driven actuator and includes a calibrated return line to manage fuel recirculation. Internal components are coated with nickel-phosphorus to resist corrosion from high-sulphur diesel fuels. The unit is compatible with OEM specifications for spray pattern, atomisation, and response time. It does not include electronic control modules and must be paired with a functioning engine control unit.
This injector is sourced by diesel repair shops, fleet maintenance operators, and aftermarket distributors in North America and Europe. Units are packaged in anti-static foam-lined boxes, with 1 to 8 units per order. Trade terms are typically FOB Qingdao or CIF port of destination. Minimum order quantity is one unit, with bulk discounts available for orders of 20 or more. Lead time is 10 to 20 days after payment.

Sourcing Duramax LB7 Diesel Fuel Injector from Yantai Maxdawn International Trading Co., Ltd - China Import Guide
Before ordering, confirm the injector's serial number matches the engine model and year. Request a test report showing flow rate, leakage, and response time for each unit. Inspect the packaging for signs of prior use, such as oil residue or damaged seals. Ensure the product is not listed as remanufactured unless explicitly stated, as performance differs from new units.
Confirm the Incoterms: FOB Qingdao is standard. Lead time is 10 to 20 days after payment, depending on stock availability. Payment terms are typically 100% advance or LC at sight. Buyers should request a commercial invoice with HS code 8413.50 for diesel fuel injectors to avoid customs delays. Shipping weight per unit is approximately 1.2 kg.
Perform a visual inspection for surface cracks, corrosion, or damaged connectors. Test each injector on a calibrated bench before installation to verify flow and leakage. Retain a sample of the fuel used for testing to trace contamination issues. Request a warranty statement and proof of origin for customs compliance, as diesel injectors are subject to import restrictions in some countries.
