Thanks for chiming in Jack. Do you feel your TCS vacuum line plumbing (i.e. rubber hoses the entire circuit) is original to your 2nd week in April built Z? If so it would appear that the metal tubing "fix" came some time after the 2nd week of April but prior to the last week in May.

Also, is your fuel line support bracket painted black? What sheen?

Thanks,
Sam
