Vacuum line kit - any recommendations?

[roscoe67]

I'm starting to get some P0441 codes on my 1996 and my lines are completely fossilized. I figure I need to replace basically every vacuum and evap line and thought that folks around here might have recommendations for a kit. True, I could open the hood in the Autozone parking lot and pull them off one by one, cutting a new length off the spools for each one. But that seems pretty time-inefficient, so I am willing to spring for a kit.

Any recommendations?

There isn't many kits.

Vacuum Hose- Toyota V6 3.4L 5VZFE 4Runner & Tacoma Vacuum Hose Kit (1996-2001) Kit-1106

A few members were discussing this topic a few weeks ago.

Some just buy silicone lines and swap. Some of the lines are discontinued from Toyota. So that makes things even worse...

Thanks, I thought that might be the case. Any recommendations on sources for the silocone lines? Or are they all pretty much the same?

That kit from Yotashop is pretty spendy, and I dont think it has every hose - at least not as pictured.

You can still source all the hoses individually from Amayama (except for three). It'll end up being a lot cheaper than the Yotashop kit.

I wonder why they wont make these 3 and also why they are not available via
dealerships?

No idea . And depending who you listen to, they are either truly discontinued or just back ordered.

I feel like it definitely makes sense to buy the tightly curved lines from Toyota. The evap system has a few s-shaped hoses.

You can bend them yourself. You dunk them in boiling water when they're in the shape you want, them cool them in ice water. The silicone lines supposedly don't hold up to oil as well, so that wont work for me.

Suggest Silicone Boost/Vacuum Hose Shop Kit, Black VAC000590 from siliconeintakes.com for $55.00. Comes with 4mm, 6mm, 8mm and 10mm I.D. hoses. Replaced all my vacuum hoses about 5 years ago with plenty left over. No issues with bending to replace those small hoses on the charcoal canister. Highly recommended by others on this forum.

And so those hold up to the gas vapor well? Vacuum is just air, but the evap does have fuel vapor in it.

And unfortunately the S-shaped evap hose is one of the discontinued ones.

Is Yotashop missing those three from it's kit?

Yes. I'm talking about numbers 10, 11, and 12 below:

It's seems we can form hoses with boiling water then an ice bath it will retain thar shape according to a member.

So if this is the case, we really just need the bulk hose to make our own vacuum line kits out of oil and gasoline resistant hoses. Which doesn't not include silicon tubing.

That may be a worthwhile experiment, I haven't seen this done before. And hopefully doing this will maintain the hoses' resistance to oil/fuel vapors?

Not to throw another monkey wrench into this, but many OEM hoses have different diameters on opposite ends of the same hose.

Just looked at my silicone vacuum hoses that I installed in 2015 and they all look and feel perfect. My 4runner is a 1998 limited and I used the vacuum hose diagram on the underside of the hood as a guide for replacement. Yes, silicone should not be used for a fuel line, however, from what I've read, fuel vapors don't seem to be a problem. It's your call.

 

[poisedforflight]

Yes. I'm talking about numbers 10, 11, and 12 below:

10 and 11 don't look like they'd be too bad with generic hose. 12 looks like a PITA to replace.

Yes that is a monkey wrench in this one I was wondering when around what degrees the smaller diameter house can be stretched with a metal form.

I would think it would be above 200 degrees more like 300 or 400 degrees because it can get up to 200 degrees under the hoods.

Now I could see forming occurring at slightly higher temperatures. I am not sure silicone tubes is are the solution.. Granted, I can see some members using them. I just don't see those lasting 20 plus years before replacement.

And 13 - that looks pretty curvy.

Do you have a good source for oil/fuel-resistant hoses, by chance?
