This part of ISO 13948 specifies requirements for mechanical, push-on connections used on diesel fuel injection pumps and fuel injectors for the connection of low-pressure fuel supply.
Two types of push-on connections (types A and B) are described in this part of ISO 13948. Type A is commonly used on diesel fuel injectors and type B on diesel fuel injection pumps.
NOTE Low-pressure connections to fuel filters are covered in other International Standards; see the bibliography. High-pressure end-connections for pumps and injectors are covered in ISO 2974.
