OVERVIEW
Factory bolt for the assigned fuel pump mounting
Genuine VW/Audi N-911-873-01 secures the designated attachment in the matching high-pressure fuel pump assembly. The socket head provides the original tool engagement while the threaded shank matches the assigned mounting point.
This listing supplies one dry fastener. The pump, flange, fuel lines and fuel are separate components; replacing mounting hardware does not correct a faulty pump or a damaged mounting surface.
Technical details
- Complete factory number: N-911-873-01.
- Factory specification: M8 × 30 socket head bolt, factory number N-911-873-01.
- Design: cylindrical socket head and threaded shank as shown in the original archive photo.
- Quantity supplied: one individual fuel pump mounting bolt.
The exact engine and pump arrangement determine its use. Match the full part number, length and original fastening position. Use the correct drive tool for the socket shown; do not force a similar tool into the head.
Common reasons to replace
- The repair procedure requires replacement of removed hardware.
- The socket or bolt threads are damaged.
- Corrosion or deformation prevents the fastener from seating correctly.
Inspect the pump flange, receiving threads and mating faces during service. A damaged mounting thread or distorted flange requires its own repair. Diagnose fuel-system faults before replacing hardware.

Installation guidance
Follow the factory high-pressure fuel pump service procedure, including the prescribed pressure relief and cleanliness requirements. Position the assembly correctly and use the specified replacement hardware, tightening sequence and torque for the exact engine.
