Petition to Amend CFR § 393.67(c)(12) Construction of Liquid Fuel Tanks

On April 5, CVSA petitioned the Federal Motor Carrier Safety Administration (FMCSA) to amend CFR § 393.67(c)(12) by removing subsection (i). The current language is outdated and no longer applicable to the current state of the industry. While the current regulation requires fuel tanks to be manufactured to allow a maximum fill of 95%, CVSA has learned from fuel tank manufacturers that liquid fuel tanks are now manufactured with a vented cap, which makes the 95% maximum fill requirement in the regulation unnecessary. There are manufacturers of large trucks equipping vehicles with tanks allowing 100% fill, based on the positioning of the filler neck and vented cap, with no resulting issues.
