A guide for the easier way to do get to get to the vacuum actuator to install the vacuum lines.

Materials needed (you can use different colored lines, these are just suggestions)(I got the colors and great quality hoses from ebay.com):
2 ft - 5mm black silicone high temp vacuum line
2 ft - 5mm green silicone high temp vacuum line
2 ft - 5mm blue silicone high temp vacuum line
2 ft - 3mm red silicone high temp vacuum line
Reuse the vacuum line splitter and anti-chafe tubing

Tools needed:
- long reach needle nose pliers
- jack
- jack stand

Procedure:
- Jack the passenger side up at the "frame" just behind the engine to lift the tire off the ground and place a jack stand under the car for safety. Set the brake, chock the rear tires. The reason you jack it up is to make it easier to work under the car and to drop the tie rod down so you can get your arm in there.
- Assemble your vacuum lines using the anti chafe material provided or replace with new material, remember it gets really hot here so if you are replacing it use something heat resistant.
- Lower the assembled hoses behind the engine roughly into place.
- Install the blue line (#3) first, this is the most difficult and you are probably not going to do it if you have large arms and fingers. The location is under the black (#0) vacuum line, you cannot see it you have to feel for it, you will feel one of the mounting bolts move your hand around until you feel the vacuum port. Grab the hose between two fingers like holding a cigarette and push it on, it is not an easy job and it can be frustrating but it is doable.
- Using long reach needle nose pliers put the other hoses on starting at the 3mm hose
- Once the lower hoses are on, connect them to the appropriate locations on the VSVs according to the diagram

It may be that my sole purpose in life is simply to serve as a warning to others.

eodgator,
Your shopping List in your original post: 3-mm, 4-mm, 5-mm, 6-mm.: these are I.D. (inner diameter) dimensions, correct?

Yes, inner diameter.

If you follow how to get to the actuator it makes it a lot easier. You may have to remove the front right tire.

If you still have the original equipment lines it's time, well it's probably past to replace them one and all.

I ordered these on ebay
- 3 meters of 6mm green high temperature silicone line
- 3 meters of 5mm red high temperature silicone line
- 3 meters of 4mm purple high temperature silicone line
- 3 meters of 3mm blue high temperature silicone line

I used almost all of it, I could have ordered 2 meters of the 4mm and 3mm but it's not expensive and I didn't want to run short. I used different colors for different sizes to make it easier to keep track of the sizes, and it looks good.

Advantages of the silicone, it is resistant to heat and most things under the hood except fuel. Don't use it for fuel or fuel vapor lines.

If you have a 2wd you won't need nearly as much 5mm

Where did you buy all those silicone high temp vacuum lines? Summit Racing, JEG'S, Amazon?

mensajero,
It's in your very Post (Post #24 ) in the portion you quoted: " I ordered these on ebay".

Amazon has them too.

I picked up the vacuum lines on eBay from a couple of different sellers but the heavy duty vacuum lines I got from hardline_co were the best quality and you can order in various increments.

eodgator, What am I missing?
How long ago did you get those heavy duty vacuum lines from hardline_co on eBAY? Today hardline_co only offers on eBay:
1/ 5-ft. increments, period, $9.98-per-5-ft. No other lengths.

2/ Colors are all 5-mm. No 3-mm, 4-mm, 6-mm. ??

QUESTION: Do us a favor? What's MINIMUM length of each 3-mm, 4-mm, 5-mm, 6-mm we can squeeze by with on RAV4 manual transmission 2WD (FWD)?

Originally I bought 3 meters (roughly 10') of each size just because I wanted to make sure I had enough, and it's not very expensive. When I redid the transfer actuator I wanted it color coded so I got 2 ft of each color which was just the right length. At that time the seller was selling by the foot. If you contact the seller and tell them what you need he may make custom lengths if not, look around on the eBay and the rest of the internet and I'm sure you'll find a good supplier.

Hey all, looking to swap out my old vacuum lines next weekend and I have a few questions:


On my rav, the line coming off the throttle body hits a sensor mounted on the air filter before landing on the charcoal canister - what is that sensor for? I'm also having an issue when I gas up, the fumes are feeding out of the gas cap instead of the canister. The lines coming off the throttle body are not fuel lines either, so hopefully I can clean that up at the same time.


I'm having low idle at cold start, sometimes so low that I need to give it gas for 30 seconds or so so it doesn't stall out. Tried cleaning out the throttle body but it hasn't helped. the idle issue is only on a cold start.



is it possible to replace all these lines with the engine in the bay? it looks like a few of them go pretty deep in there, but I'd really like to replace them all at once without taking the engine out.


Thanks for the write up! excited to finally get the center diff lock working..


cheers!
