99 grand prix. changed original fuel filter. quick connect fitting pulled apart. small plastic spacer and bits seized onto steel filter nipple so fitting pulled apart. i tore o-ring and GM dealer made a mistake and sold me new o-ring which is for the hex end of filter. seems they have no listing for o-ring i need. i put QC back together and tried to use another o-ring but have small leak. i can buy new QC fuel line, or get hose end repair kit at parts store or go to junkyard and find donor car and extract used o-ring?
