The area surrounding the injection pumps on later model 4 valve ISC 8.3 liter and ISB 5.9 liter engines is very difficult to access when removing the fuel supply lines. This specialty socket has been designed with a custom slim configuration and a 3/8" square drive to fit into this confined area. Not for ISM engines.
