Vacuum Hose Sizes / Vacuum Kit

Have a 2.4 and all my vacuum hoses under the hood are dry rotted. Can someone tell me the most used sizes under the hood? I assume they're metric size. OR, if anyone knows of a master vacuum replacement kit.

 

I used these:

$40 Upgr8 Universal 4mm/6mm/8mm/12mm Inner Diameter High Performance Silicone Vacuum Hose Kit (Blue)

Almost all of the Amazon Review pictures are from people using them on 4runners/tacomas.

Replaced all vacuum hoses and they've worked great. From my experience the silicon lines are not good for the PCV hose though.
I'm not sure if they're safe for coolant hoses, but I may try it out since I need to replace my IACV coolant lines.

 

@time623 I seen these, maybe im old but I dont want blue or red. Want black haha.

 

I replaced 60% of my hoses
I went to multiple family owned hardware stores…..like Ace hardware
Surprisingly, I found 4 different sizes I needed
But
They were in red
I’m not ‘that guy’ as far as color under the hood = HP
And RA sent my red plug wires…
But I went with it bc most expensive was $2.79 per ft

 

@ControlCar do you remember what sizes you ended up getting?

 

Kit here - https://www.siliconeintakes.com/liquid-air-adapter/silicone-boost-vacuum-hose-p-591.html

Kit includes the following:

(10) 4mm Black Silicone Boost/Vacuum Hose Per Ft.
(8) 6mm Black Silicone Boost/Vacuum Hose Per Ft.
(4) 8mm Black Silicone Boost/Vacuum Hose Per Ft.
(4) 10mm Black Silicone Boost/Vacuum Hose Per Ft.

Middle 2 being the most I used but have 2 first gens so could also get a good start on the other one too

 

You'll be missing out on the massive horsepower gains from blue/red hoses

 

man I took old ones(4 sizes) to store
And matched up
They did have black ones but for some reason, more sizes in red

 

I ended up ordering this Kit, I will update how they are once I install them.

$24 EVIL ENERGY 5/32 1/4 5/16 3/8 Silicone Vacuum Tubing Hose Line Kit 5FT 4PCS 130PSI Max Pressure (4mm 6mm 8mm 10mm)

Seems to be a pretty good kit. Mixed reviews out there if they will hold up on the EVAP system. Time will tell. They're 100% better than what was there. Every hose on my evap system was cracked / damaged / split.
