5-Piece Injection Cap Socket Set for VAG Bosch TDI/SDI Fuel Injection Systems

Brief Overview

This is a precision injection system service kit purpose-built for VAG Bosch TDI and SDI diesel engines. The set contains five specialized sockets designed specifically to access injection pump covers, regulate fuel dosage valves, and remove pressure-regulating components that standard socket sets cannot reach. If your shop services VW, Audi, or Skoda diesel platforms, this kit eliminates improvisation and reduces the risk of component damage during critical fuel system work. Complement your injection service capabilities with specialized diesel injector line removal tools to establish a complete fuel system service lineup.

Key Features

• 7mm socket – Designed for injection pump cover adjustment on EDC systems (1996–2003)
• 12.6mm socket – Fits Bosch injection pump quadrangular groups with 1/2-inch drive compatibility
• Triangular socket (cap screw) – Accesses and loosens injection pump cover fasteners
• Triangular socket (dial gauge) – Permits pressure measurement and cover nut removal during calibration work
• VP37 pressure regulator socket – Specifically sized for pressure-regulating valve service without rounding or slipping
• Professional carrying case – Molded blue plastic case with individual foam recesses ensures tool organization and safe transport between job sites
• Metal construction – Chrome-finished and hardened steel components resist corrosion and repeated use stress
• Laser-etched markings – Clear identification on each socket for quick selection

Why This Set Drives Profitability

High-Demand Service Market: VAG TDI/SDI diesel engines remain common in European commercial fleets and specialty automotive markets. Fuel injection service is high-touch, high-labor-hour work that generates recurring revenue.

Eliminates Improvisation: Mechanics without these sockets resort to grinding, drilling, or using incorrect tools. This kit positions your shop as equipped and professional, justifying premium labor rates.

Low Wear Profile: Injection system work is occasional (not daily grinding). These sockets retain their condition across multiple seasons, reducing replacement demand but ensuring steady margin per unit sold.

Complete System Coverage: Bundle this set with multi-tooth pump removal sockets to offer mechanics a comprehensive injection service solution, increasing perceived value and attachment sales.

Fleet Service Credentials: Shops equipped with VAG-specific tools attract fleet maintenance contracts where diesel engine diagnostics and fuel system work are standard requirements.
