fuel line metal tube

["Walter" <Whalt@xxxx>]

I am replacing my fuel line (part # 106983) and forgot to order the
compression rings that go with it. According to my tube sizing gauge, this
fuel line appears to be a standard 5/16th inch metal tube and would
therefore take standard American plumbing compression rings. Is this true,
or should I order the compression rings from a D vendor? Time is of the
essence with this project. I thought something like this would have a
metric size to it. No?
