Product Description
High-Pressure Injection Pipe 8-97148964-0 8971489640 For ISUZU NPR/NQR 4HE1 4.8L 1998-2004
Product Overview
The Injection Pipe No. 2 (PIPE; INJ NO 2) with OEM number 8-97148964-0 (also listed as 8971489640) is a verified direct-fit replacement for the #2 cylinder high-pressure fuel line on ISUZU 4HE1 4.8L diesel engines. This precision-engineered pipe is a critical component responsible for delivering precisely metered, high-pressure diesel fuel from the injection pump to the #2 injector.
- OEM Specification: Precision-engineered to exact OEM length, internal diameter, and cone seat geometry
- Proven Durability: Constructed from high-quality, high-speed steel with machined exterior finish
- Precision Fitment: Precisely bent tubing ensures proper fuel delivery routing
- OEM Cross-Reference Verified: Replaces 8971489640, 8-97148964-0, 897148-9640, 8-97148-9640
Failure Symptoms
If your injection pipe is failing, you may experience one or more of the following symptoms:
- Diesel Fuel Leaks: Visible fuel seepage or wetness near the #2 injector or along the pipe
- Hard Starting: Extended cranking time before the engine starts
- Engine Misfire: Rough running or misfiring, especially under load
- Loss of Engine Power: Significant reduction in acceleration and overall performance
- Strong Diesel Fuel Odor: Noticeable fuel smell in the engine bay or cabin
- Visible Damage: Cracks, corrosion, or deformation on the fuel line
⚠️ Important Safety Notice: A cracked or leaking injection pipe under high pressure creates a serious fire hazard and can cause cylinder misfire. Prompt replacement is essential for safety and engine performance.

Installation & Maintenance Recommendations
⚠️ CRITICAL: Professional Installation Highly Recommended
High-pressure injection pipes operate under extreme pressure. ISUZU service manuals explicitly mandate that injection pipes must be replaced with new ones whenever removed - these are single-use components.

Pre-Installation Checklist:
- Do not reuse old injection pipes - they are single-use components
- Do not bend or modify injection pipes
- Depressurize the fuel system before starting work
- Clean the area around the injector and injection pipe connections
Installation Guidelines:
- Depressurize the fuel system and disconnect the negative battery terminal
- Remove the old injection pipe from the #2 injector and injection pump
- Clean the connection surfaces thoroughly
- Install the new injection pipe with correct orientation - no bending or modification allowed
- Torque the pipe connections to manufacturer's specified torque settings
- Prime the fuel system and check for leaks
- Start the engine and inspect for fuel leaks around the connections
Maintenance Schedule:
- Inspection: During routine fuel system service or if fuel leaks/performance issues appear
- Replacement: Immediately if failure symptoms appear
- Note: High-mileage engines may benefit from replacing the full set (pipes #1-#4)
