Overview

ISO 7612:2018 specifies mounting dimensions for base-mounted in-line fuel injection pumps and high‑pressure supply pumps used with common‑rail fuel injection systems for diesel (compression‑ignition) engines. This fifth edition (2018) updates the previous 2009 edition and provides standardized figures and tables that define dimensions and tolerances (in millimetres) for several pump types to support mechanical interchangeability and consistent engine integration.

Key topics and requirements

Scope: Dimensional requirements for base‑mounted in‑line pumps and two‑cylinder high‑pressure supply pumps for common‑rail systems.

Figures and tables: Detailed Figures 1–7 and Tables 1–4 present mounting layouts, hole patterns and nominal dimensions for different pump types and cylinder counts.

Dimensions and tolerances: All specified dimensions are in millimetres; tolerances are provided where applicable. Dimensions not specified in the standard are left to the manufacturer’s choice.

Shaft taper reference: The standard refers to ISO 6519 for tapers of shaft ends and hubs-ensuring consistent shaft interface specifications.

Edition notes: The 2018 edition cancels ISO 7612:2009, removes a type no longer in serial production, and corrects a previously reported dimensional error.

Applications and practical value

ISO 7612 is primarily used to:

Enable OEMs and engine designers to adopt standardized pump mounting interfaces, reducing design iteration and assembly issues.

Allow fuel pump manufacturers to produce units that fit a range of engines and mounts, improving interchangeability and aftermarket compatibility.

Support service and repair operations by ensuring replacement pumps match existing mount dimensions.

Aid CAD modelling, fixture design, and production tooling by providing precise mounting layouts and hole patterns.

Streamline supply chain and regulatory processes where dimensional conformity is required for fitment and safety.

Typical users include automotive and heavy‑duty engine manufacturers, fuel pump suppliers, powertrain engineers, aftermarket vendors, testing laboratories and maintenance workshops.
