Fuel Injection Pump Socket 33 Point for Mercedes Benz Diesel

A fuel injection pump socket made for work on Mercedes-Benz diesel injection pumps. The 33-point spline profile, 1/2in drive and 56mm length give a secure fit and the reach needed when access around the pump is limited.

Used for servicing and maintenance on compatible Mercedes-Benz diesel engines, this socket suits mechanics, garages and experienced DIY users carrying out pump-related work. It is particularly useful when working in tighter engine bay areas where a standard socket may not seat correctly or give the access needed. Also suitable for many early 250 and 300 models with in-line fuel pumps, making it a handy choice for older Mercedes diesel maintenance.

The socket is sized specifically for this application, helping reduce the risk of poor fit when working on the correct pump type. A 1/2in drive makes it suitable for use with common ratchets and breaker bars already found in most garage and workshop tool kits. The 56mm length gives a bit of extra reach without being overly bulky, which can help when working around surrounding components. For regular servicing on the listed engine series, it helps keep the job straightforward and avoids using general-purpose sockets that may not fit as intended.
