Hey guys -- for those of you who've done their vacuum lines, what where did you get your stuff from and how was it?

 

Hose techniques kit. Rx7store.net

I'll never use anything else unless they quit selling them.

 

aw mahijik they dont have yellow

 

Trust me, you don't want yellow anyways. When it gets dirty, it looks real nasty.

 

what would you recommend red or blue?

 

neither - I know everyone has different opinions. However, silcone has proven, time and time again NOT to hold up to liquids. That's why the other website says "not for fuel or oil applications"

Get this. It is pricey, but you will never had to buy another vacuum line... EVER.

I used red. To be honest, I wish I just used black. Wouldn't be flashy, but you wouldn't worry about it getting dirty and looking like crap.

 

I still don't understand why people perpetuate things like this. Those are "vacuum lines" people are replacing, not oil lines. Those lines do not transport liquids. The few lines which might see any kind of oil (in the case of a problem) will never see enough to degrade decent silicone hoses (namely the oil injector vacuum source lines).

 

I posted this on another thread, so here I go again. If you are EVER going single, or thinking of going single, or might go single in 2 years ( I hope you get the point) use silicone. I have a viton kit and LOVE it. Great product etc, but I am now going single. So it becomes money wasted. Everyone wants to keep the twins untill they burn up or run out of breath. Think about it.

 

Sorry what? Use silicon, but you LOVE the viton kit? I don't understand why the viton kit would be wasted money? Just because you remove it all?

Also -- i've read a few good ways to remove the old vacuum lines easily, one of them was a butane torch used to heat and exact knife or stainless steel scalpel -- how'd this work?

What kind of troubles do you guys have with vacuum lines popping off with only the micro zip ties? Is that effective enough?

 

Mahjik,

I hate to argue with you since you are such an asset to this forum. To a point you are absolutely correct. The lines are for vacuum, not oil and fuel.

HOWEVER.... eventually, some fuel or some oil will touch those vacuum lines. It IS an FD after all. Then it's just a matter of time until they fail. The only liquid that they seem to resist is coolant.

Like the previous post said... if you're going to go single.... then by all means save the money since they will surely hold up for some time. If you're going to stay with the twins spend the money and NEVER have to worry again.

 

Oil touching and oil soaking the lines are two different things. The conditions that the silicone oil test was done won't happen unless you either:

a) run hot oil through the lines
b) submerge the lines in hot oil

None of those conditions will exist with the FD vacuum line system. Disagree all you want, but people have been using silicone on these cars for years without issues, oil spills and all.

I agree, silicone lines should not be used for oil or fuel lines. However, the FD vacuum lines for emissions and turbo control see neither except for a small few (the purge control line could see some fuel mist, but would not be a continuous flow; oil injection vacuum source could see some oil, once again wouldn't be a continuous flow).

Viton is a good alternative for people who want to spend the money, but it's not going to offer any better performance or protection for the FD's use.

 

just a question if you had a brighter color couldn't you see cracks or anything to ever spot a leak? just a question dont flame just curious to know

 

I'm not making this up. Rare occurence??? Maybe, maybe not. However, it happened to me. Personal experience goes a long way. I was originally under the same impression that silicone was the end all. While they are superior to the rubber hoses... I just don't have the same faith in them anymore. Oh well......

 

Honestly, most if any cracks or splits are going to occur in places you aren't going to easily be able to see.

 

Then you probably had some really low grade silicone lines. Not all silicone lines are created equal. The stuff carried by local shops like NAPA, Autozone or other places are extremely thin. The lines from Baker are much thicker and robust, made for race applications.

 

How good are the baker hose's when it comes to kinks?

 

I've never had a kink so I don't know if that answers your question or not. Since they are thicker than the cheap stuff, they don't create extreme bends/kicks nearly as easily.
