In aircraft maintenance circles this would be known as a trend. As Nippy suggests it is probably wise to replace them. You don't want fuel spraying onto a hot engine. Later cars only have these compressed clips on the inter-connecting pipe. Someone said they had problems removing them. A thin screwdriver and a gentle tap in direction of the arrow will unlatch them. (if it is this type)
