FAQ

Q1: How do I confirm these nozzles will fit my engine?

A: Please cross-reference your existing part number with our listed OEM numbers (DLLA35S376, DLLA35S377, DLL140S382, DLLA79S390). Measure the physical dimensions (length and diameter) and verify the spray angle and opening pressure with your engine service manual. Our standard nozzle type is compatible with many mechanical injection systems.

Q2: What is the installation process for this mechanical nozzle?

A: Installation requires careful handling to avoid contamination. First, clean the nozzle holder seat thoroughly. Lubricate the nozzle body lightly with clean diesel fuel. Tighten the retaining nut to the manufacturer’s specified torque (do not overtighten). After installation, bleed the fuel system and check for leaks before starting the engine.

Q3: How can I maximize the lifespan of these nozzles?

A: Use clean, high-quality diesel fuel and replace fuel filters regularly. Ensure the fuel injection pump is in good working order to maintain correct pressure. Periodically inspect nozzles for carbon buildup or wear. Following a preventive maintenance schedule can extend service life beyond the standard 6-12 month warranty period.
