Elements

BASIC GUIDE TO ELEMENTS

The Bosch fuel injection pump is one of the greatest gifts Mercedes gave the older Mercedes models.

It is very robust very tuneable and if built correctly a very long lasting part of the vehicle. These pumps when rebuild with larger internals are very valuable and have an excellent resale value.

This is the key element (no pun) to increasing the engines power and fuel efficiency.
