Thanks mate

Thanks for reply mate, that piece came off when i removed the bottom bracket to get the fuel pump out. Is there anything else between the pressure regulator and the filter apart from the o ring itself? I just changed the new filter z646 and hope the hard starting issue get fixed but it get worst now, checked all the o-ring and the new seal at the pump, i finally put everything back together without that round piece, i can hear it pinging at idle but when driving is oke, still hard to start after turn off for awhile. Anyone got a picture of the complete fuel pump assembly? I might have to buy the whole new pump assembly tomorrow and hope it gonna fix :) 

Hi guys, i have recently replaced the fuel filter on the corolla zze122 and one of this small round piece of plastic came off but i couldn't figure out where it belongs to :( please help hix :)
