Description / Abstract: Introduction

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. This document provides the standard technical requirements for the integrated fuel tank assembly. This document shall only be used when invoked by a program specific technical specification. References to the program specific technical specification are included in this document where program specific requirements are expected to exist.

The program specific technical specification may include additional program specific requirements that are not referenced in this document and may supercede any requirements included in this document. In the case of any conflicts between this document and the program specific technical specification, the program specific technical specification takes precedence.

This specification establishes the integrated fuel tank assembly requirements for General Motors gasoline, gasoline blend, and diesel fueled vehicles. The functions, performance, design constraints, and validation required of the integrated fuel tank assembly are directly defined in this document or a reference is made to another document.

Refer to the Fuel Pump Module (FPM) Component Technical Specification (CTS) for requirements specific to the module.

This document contains component technical specifications common to all programs. Reference the program/vehicle specific document for additional requirements unique to the application.

Applicability. This specification applies only to gasoline, gasoline blend and diesel fueled vehicles. It includes requirements for both complete and incomplete vehicles, and for specific applications, such as police and taxi use.

Remarks. The integrated fuel tank assembly is a functional vehicle component for receiving and storing fuel; sensing and signaling fuel quantity; supplying fuel to the engine; and (for gasoline only) managing both refueling vapor and fuel vapor generated during use of the vehicle by the vehicle operator. The integrated fuel tank assembly is to carry out these functions while meeting specific requirements of the customer, the powertrain, other interfaces, mandated safety and emission standards, and company objectives.
