Good Evening Guys,

I am planning on replacing every vacuum hose I can on my 1991 T-10 Blazer 4.3L Z. All are dry rotted. I was wondering if anyone knew about what diameter sizes and length approximations I should buy to get the job done. Any help would be greatly appreciated.

Thanks

 

Great question as I will be going through this myself on the same truck.
