Frequently Asked Questions

Installation Process	Refer to the "Step-by-Step Installation Guide" on our product details page for detailed installation instructions.
Pre-Installation Precautions	Ensure dust-free environment; lubricate O-ring with clean machine oil; verify correct O-ring installation to prevent oil leakage.
Engine Issues After Replacement	Commonly caused by air in high-pressure oil rail. Cycle engine in short bursts (max 30 seconds) to purge air. Multiple attempts may be needed.
Compatibility Verification	Provide Engine Serial Number (ESN) for free compatibility verification if unsure about machine fit.
Fuel Injector Replacement Indicators	Cylinder Cut-out Test: Use diagnostic software to shut off cylinders individually and observe engine speed fluctuations Fuel Rail Pressure Test: Check for internal leaks preventing proper pressure buildup Back-leakage Test: Excessive leakage indicates worn internal control valve assembly Visual Inspection: Check nozzles for carbon buildup, blockage, or corrosion
Delivery Timeframe	Varies by country/region and customs clearance. Contact us with address and postal code for shipping cost and delivery estimate.

Step-by-Step Installation Guide

Important Note:

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. Inspect injector sleeve for pitting or erosion.

2. Lubrication

Apply clean engine oil to the three O-rings and backup rings. Never use grease. Use only clean engine oil to ensure seals slide in without tearing.

3. Seating the Injector

Push injector down firmly by hand until it "seats." Install hold-down clamp and bolt.

4. Torque Specifications

Tighten bolt to 30 N⋅m±7 N⋅m (22 lb-ft). Note: Over-tightening can crack injector body; under-tightening causes combustion gas leakage.

5. Trim Code Programming

Locate 6-digit alphanumeric code on top of injector solenoid. Use ET (Electronic Technician) software to program this code into ECM for precise fuel delivery synchronization.

Troubleshooting Guide

Issue	Root Cause	Solution
Black Smoke	Poor spray atomization or stuck needle valve causing dripping	Inspect air filter
Hard Start	Internal leakage in injector leading to insufficient starting oil pressure	Inspect injector O-rings and internal seals
Engine Misfire	Faulty solenoid valve coil or worn internal valve components	Inspect wiring harness connections and replace damaged injectors
