Replacement Vacuum Hoses

Guys I'm about to do valve cover gaskets on my 2001 with the 3.4L. It looks like several of my vacuum lines will need to be replaced. Has anyone tried the preformed silicone hose kits and been happy with the fit? Would anyone have a source for the common metric sized vacuum hoses used on these trucks? Thanks for any help you can offer.

I checked a previous discussion and it looks like @Wulf might have done his.

I believe I used this kit

I replaced all the vacuum lines on my 3.4 V6. Toyota uses some truly weird sizes and bends. In one case, one end is thicker/bigger on the same freakin hose. Some I was able to replace for cheap, and there are two or three lines that you'll only find at a Yota dealership, and those are like $10+ each!.

 

Sorry to be so slow in getting back in here to thank you guys. I really do appreciate the help.
