Does anyone have an extensive list of part numbers for the pre bent hoses, or can anyone point me to a thread on here where that info is listed / a company that makes these? I was thinking about ordering 15ft of silicone hose but then I realized that 90% of the hoses are pre bent. Pesky Toyota. I know I dont absolutely need the bent lines but it will look cleaner with the OEM supplies.

I just went to o'reilly's and got 10' of different sized hoses. they radius just fine and IMO silicone is way overkill for these engines. I run a supercharger and I have never found a reason to go silicone. normal vac hoses seem fine.

you will want 3mm,5mm,7mm if I remember correctly.

otherwise I compiled a list a while back and I know the hose on the back on the air intake that goes to the drivers side head... I can't find a part number for it. sure it exists I just was never able to locate it.

I think once you add up the price for these you will head the generic route, hope it help?

Okay! I appreciate it! I was thinking silicone only so I never need to do them again because I'm under the impression that it wont crack over time? But I could be wrong. I appreciate that info!! I'll look over it after work / school

I bought a silicone hose kit Made by Mr. Gasket in Silver off eBay for around $15.00 which included different sizes. I was able to do several vacuum hoses and the coolant hose for the reservoir as well as the ones for the windshield squirters with some leftover.

I'm seeing the Mr. GASKET kit is 4mm 6mm and 8mm is this the sizes your kit came with? And did they fit snug?

Mine was 3, 6 and 10mm.

Hmmm okay I'll keep looking, thanks for the response!

Brand new here, but I'm looking to buy some hoses to replace some that are showing some wear. What sizes did you end up going with? I'm looking to just do them all and not have to worry about them again

Silicone Boost Vacuum Hose

50 bucks all silicone. More than enough to cut to size for the entire vacuum system.

You rock. This is a useful link! Should be easy to convert to all silicone with this set.

Needed? Probably not. But if mine are showing signs of cracking and stuff, might as well upgrade

I still recommend the silicone hoses for everything except the pcv hose, mine turned from blue to brown because all of the oil lol.

Why does everyone like silicone? Seems like the factory hoses held up for 20+ years.

I guess not all the factory hoses are available anymore. Stupid disposable world.

There are recently compiled lists of still-available OEM P/Ns for vac hoses here on T4R somewhere. Hoping someone will chime in. I want to do as many as I can soon.

I just did all of mine using OEM parts, so I have the full list, including air, vacuum, and fuel hoses. I was able to get all the hoses except three which are discontinued.

When I find some time I'll put the list together and post it.

I'd love to get that list when you have time.
