Description / Abstract:
This SAE Recommended Practice was developed primarily for
passenger car and truck applications but it may be used in marine,
industrial, and similar applications.
Purpose
The purpose of this document is to provide dimensions for two
types of threaded fuel tank filler caps (pressure/vacuum and
nonvented or vacuum only) and the corresponding cap retainers (see
Figures 1 and 2). The use of these dimensions prevent the use of a
nonvented or vacuum only cap with a pressure/vacuum cap retainer.
However, these dimensions will allow a pressure/vacuum cap to be
used on a nonvented or vacuum only cap retainer.
Rationale
This document was revised in accordance with the scheduled five
year review. The text in paragraph 1.1 was clarified.
