Hi, can somebody assist and share experience. When tried to connect the fuel connector with the fuel pump one of the o rings broke. There are 3 of them, green, black and beige + a plastic ring. They all sit in front of the blue clips on a pipe. Don't know what I've done wrongly! These o rings are not listed as spare parts nor I could find a complete connector as a separate part. Probably all comes as a fuel hose set at around EUR 100. Any advise? Thanks.
