Frequently Asked Questions
How do I install my fuel injector after purchasing it?
Refer to the detailed "Step-by-Step Installation Guide" below for comprehensive installation instructions.
What precautions should I take before installing my fuel injector?
Ensure a dust-free installation environment, lubricate the O-ring with clean machine oil to prevent leaks, and verify correct O-ring positioning.
Why is my engine still unusable after replacing the fuel injector?
This typically occurs due to air trapped in the high-pressure oil rail. Cycle the engine in short bursts (under 30 seconds) to purge air. Multiple attempts may be needed to stabilize pressure.
Is my device compatible with this part number of fuel injectors?
For compatibility verification, provide your Engine Serial Number (ESN) for free confirmation.
How to determine if your fuel injectors need replacing?
  • Cylinder Cut-out Test: Use diagnostic software (ET) to shut off cylinders individually and monitor engine speed changes
  • Fuel Rail Pressure Test: Check for internal leaks preventing proper system pressure buildup
  • Back-leakage Test: Excessive back-leakage indicates severe wear of internal control valve assembly
  • Visual Inspection: Examine fuel injector nozzles for carbon buildup, blockage, or corrosion
How long will it take to receive my package after payment?
Delivery time varies by destination and customs processing. Contact us with your address and postal code for accurate shipping costs and delivery estimates.
Step-by-Step Installation Guide
HEUI (Hydraulic Electronic Unit Injection) systems are extremely sensitive to contamination. A single speck of dust can cause premature failure.
  1. Preparation: Thoroughly clean injector bores. Remove all carbon debris, old O-rings, and fuel/oil residue from the seat bottom. Inspect injector sleeve for pitting or erosion.
  2. Lubrication: Apply clean engine oil to the three O-rings and backup rings.
  3. Warning: Never use grease. Only clean engine oil ensures seals slide in without tearing.
  4. Seating the Injector: Push injector down firmly by hand until it "seats." Install hold-down clamp and bolt.
  5. Torque Specifications: Tighten bolt to 30 N⋅m±7 N⋅m (22 lb-ft). Over-tightening can crack injector body; under-tightening causes combustion gas leakage.
  6. Trim Code Programming: Locate 6-digit alphanumeric code on injector solenoid top. Use ET software to program this code into ECM for precise fuel delivery synchronization.
Troubleshooting Guide
IssueRoot CauseSolution
Black SmokePoor spray atomization or stuck needle valve causing drippingInspect air filter
Hard StartInternal leakage leading to insufficient starting oil pressureInspect injector O-rings and internal seals
Engine MisfireFaulty solenoid valve coil or worn internal valve componentsInspect wiring harness connections and replace damaged injectors
