SAE J829-2019 PDF

Scope: This SAE Standard was developed primarily for passenger car and truck applications for the sizes indicated@ but it may be used in marine@ industrial@ and similar applications. Purpose The purpose of this document is to provide dimensions for three fuel tank filler cap types (vented@ non-vented@ and pressurevacuum)@ and the corresponding cap retainers. Use of these dimensions preclude the use of a vented or non-vented cap with a pressure-vacuum cap retainer. In addition@ these dimensions insure that a pressure-vacuum cap will not seal to a vented cap retainer. These dimensions will@ however@ allow the use of a pressure-vacuum cap on a non-vented cap retainer. (See Tables 1A and 1B and Figures 1 and 2.)
