This injection pump mount is designed as the direct-fit bracket for Delphi high-pressure injection pumps used on 1.4 HDi 16V (8HY) engines in Citroën and Peugeot models. If you are a professional mechanic or a DIY enthusiast, this sturdy mounting bracket restores correct pump positioning, reduces vibration and stress on the fuel system, and helps maintain reliable fuel delivery. The part is commonly searched by OE numbers 9643421980 and 192654, so use those codes when locating the exact fit for your vehicle.

Technical Information

• Manufacturer: Delphi / Stellantis (Citroën, Peugeot)
• Model: 1.4 HDi 16V 8HY; Fits Citroën C3, Peugeot 1007
• Product Codes: 9643421980, 192654
• Other Numbers: NFP

Function And Benefits

The bracket secures the high-pressure injection pump to the engine, keeping pump alignment and mounting stiffness. Correct mounting is essential to maintain pump timing, avoid excessive vibration, prevent leaks at fuel lines, and reduce wear on pump bearings and drive components. Replacing a damaged or corroded bracket restores factory geometry and helps prevent secondary failures in the fuel system.

Common Failure Causes

Bracket problems typically result from corrosion, metal fatigue, impact damage (collision or road debris), or a seized/overstressed injection pump that transmits excessive forces to the mount. Stripped threads and damaged mounting bosses are frequent after improper previous repairs or overtightening. The bracket itself is not a scheduled wear item and is normally replaced only when damaged or when pump removal is required.

Recommended Installation

• Work Safely: Disconnect the battery and relieve fuel pressure before beginning.
• Access: Remove interfering components (intake ducting, engine covers or brackets) to gain clear access to the pump and mount.
• Mark Pump Position: Before loosening, mark the pump orientation relative to the engine to preserve timing and alignment during reinstallation.
• Support Pump: Use a suitable support to hold the injection pump while removing the mounting bolts.
• Replace Bracket: Remove fasteners, fit the new bracket, and install clean or new bolts as required.
• Tightening: Tighten all fasteners to the manufacturer’s torque specifications and sequence. Use thread locking where specified by the vehicle manufacturer.
• Reassembly And Test: Reinstall removed components, reconnect the battery, prime the fuel system if necessary, and run the engine to check for leaks and secure mounting.

Installation Recommendations

Always Inspect Mounting Hardware: Replace corroded or stretched bolts and check surrounding mounting points for damage. Preserve Pump Timing: Marking pump position before removal avoids timing shifts that can cause poor running or hard starting. After Installation: Check Fuel Lines And Connections For Leaks And Secure All Clips And Supports To Prevent Vibrations.

Why Replace This Part

Replace the bracket when you observe visible damage, excessive play at the pump, stripped threads, or if the pump has been removed for service. Timely replacement prevents secondary failures—such as line fractures or accelerated pump wear—and ensures stable fuel pressure and engine performance.

Support the injection pump or fuel lines to avoid strain during bracket removal. Remove the old bracket with care—keep the new bolts provided and install the complete assembly in the original orientation. Clean mating surfaces and threads before fitting. Use correct torque values from the vehicle repair manual for the mounting bolts and, if required, a medium-strength threadlocker on bolts that experience engine vibration. After installation, check for fuel leaks and re-check bolt torque after the engine has reached operating temperature.

Why This Part Typically Fails

Common causes of bracket failure include corrosion of the mounting points, metal fatigue from long-term vibration, impact damage from collisions or improper jack/support points, and thread wear from repeated removals or overtightening. Failure can also follow replacement or repair of the injection pump if the bracket is not reinstalled correctly or bolts are reused when they should be replaced. Addressing the underlying cause promptly prevents additional stress on the injection pump and fuel lines.

For mechanics and experienced DIYers, replacing the rear injection pump bracket is a straightforward repair that significantly improves pump stability and reduces risk of fuel line stress.
