Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 13948 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 13948-2 was prepared by Technical Committee ISO/TC 22, Road vehicles,
Subcommittee SC 7, Engine equipment and filters for use on road vehicles.
ISO 13948 consists of the following parts, under the general title Diesel engines — Fuel injection pumps and fuel
injector low-pressure connections:
� Part 1: Threaded connections
� Part 2: Non-threaded (push-on) connections

Introduction
It is recognized that a large variety of low-pressure connections on fuel injection pumps and injectors exist, using
different sealing principles as well as designs. This International Standard attempts to provide the user with a
common set of preferred types.
ISO 13948 is divided into two parts, covering threaded connections (ISO 13948-1) and non-threaded (push-on)
connections (ISO 13948-2) for use with low-pressure fuel supply and return, boost air pressure and lubricating oil
supply and return.

Part 2:
Non-threaded (push-on) connections
1 Scope
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
