Please tell how much of each size vacuum hose I need to replace all vacuum lines in my stock '73 GMC.
I couldn't find this info in the archive.
Thanks, George in Flagstaff

George,
I seriously doubt anyone will be able to provide that information. I would suggest you remove the air cleaner and take photo of the
vacuum hoses on your GMC. This will provide a routing "schematic." Next label each one of them at the ends and take another photo.
When you're sure you've got everything labeled and photographed in such a way to allow you to reconnect them all correctly remove
them and measure the ID, the OD and length of each and you should be able to tell how much you need of each.
Regards,

After doing the very interesting vacuum line measurements, please list your findings on the forum. Saves the information forever.
Also, annotate the engine size. I'm going to jump to the idea that there is a difference on routing between 455 & 403.
Rob's photo idea is one that I use on every task I do on the GMC. Senior moments kill my memory.
