Does anyone have a list of the sizes and the total length I would need to replace all the rubber hoses on the GMC?

I already replaced all the fuel and vent lines and the vapor separator.
Along with the tank selector valve.

Had a problem with some vacuum leaks so that is also high on the list.

I am not going to wait for hoses to start leaking or fail outright.
I figure if I do it now it is one less thing to worry about.
Trying to make it as reliable as a 42 year old vehicle can be made.

I would measure the hose sizes myself but it is sitting at Sirum's about 200 miles away.
