I'm trying to replace the fuel filter on my 99 model petrol 306 but I can't detach the fuel lines from the original filter. The ends of the fuel lines that connect to the filter have some kind of attachment rather than 'worm drive' hose clips. Has anybody seen these and know how to release them? Thanks in advance, Best regards, [email]jerry.carwile@balcanicsoft.com[/email] [email]webmaster@bankarea.com[/email] [URL]http://www.bankarea.com[/URL]
