i swear to god, if one more of these old god damn brittle *** vac lines break ...... any who, anyone ever replaced all of them? most of you know im a poor bastard these days... so how much does it cost to replace all the vac lines?

just a thought, dont really give a **** either way, just killing time while im soaking some vac lines.. so maybe i can use them for a while.. and actually start my car been working on this bitch for almost 35 hours straight, good ******* times!

 

it doesnt cost much, just order about 6 feet of vaccum line from anyone you want. dont get the autozone stuff cuz it colapses when it gets hot. then replace them one by one so you dont get them mixed up.

 

get about 5 feet of vacuum line and just trim pieces to length and replace them one at a time. of course the UIM will need to be removed and if the gasket tears then you will need a new one, all in all, cheapest route to replace all of the lines is about $10 for the line, no other parts needed if you can save the intake gasket. i did all of mine, was simple and took about 30 mins with the intake off.

 

id suggest silicone vac line. i have a total of 20 feet of silicone vac line i got for about 92 cents a foot.

 

i bought some hoses at home depot, kind of like refrigerator lines but is thick. i replaced most of my vacuum/boost lines and some of my coolant. wasn't very expensive either, it's called braided vinyl tubing and can support 25 deg F to about 150 deg F and can be used for low pressure, water, and air lines.

 

dude, our engines run at 180 F. i hope youve got the wrong specs for the tubing or they arent going to hold up

 

^^I was wondering the same thing?? Is that how hot the motor is?? Unlavvful, where did you get the specs??

 

i have 3 vac. lines on my motor
fk emission

MWAHAHAHA

 

I found a silicone vacuum line kit at either Autozone or Advance Auto.......it was in metric measurements too.....was like $16 and I was able to replace almost every vacuum hose under the engine bay.

Like someone else suggested....do one at a time and you will be fine. It really helped smooth my idle out and the car starts easier with the new lines in place.

 

Yep thats what Im doing right now. I was taking my tb off to mod it and a bunch of them snapped so I bought my kit for 16 bucks from autozone in blue and the kit gave me enough length and different sizes to get almost every single vacuum line replaced.

 

i have more than three but less than 7. No emission either! just plugs. everywhere.

 

I have the same kit from autozone on my car, im now going to get different vac lines cuz these suck. when your car is fully warmed up, try squeezing the different vac lines. they are so soft at any warm temperature they almost collapse at idle.
I believe this is the best stuff you can get

IMHO using silicone vacuum hose is a waste of money...

ya but if youve ever seen the stuff from hose techniques, its really high quality. and its good up to 25 in. hg. (3 times the vacuum our cars would ever put out)

 

eh, well since my car is fucked up for a while anyways, im gonna go ahead and replace all the vac lines, IF i can remember where they all go... cause im pretty sure i fucked up some vac lines putting it back together before it broke on me last night...
but oh well ... i'll get the bitch done one way or another

 

this should be called

rotaries generally put out around 20 inHg at idle. up to 0 pressure (30 inHg) during deceleration.

 

does anyone know where to get the viton hoses that are in that article amur posted

 

McMaster Carr

http://www.mcmaster.com/

 

It's *very* expensive stuff. I tried to get prices (out of curiousity) after seeing that article. It would have cost me in the neighbourhood of $400CDN to do my car. Since I don't drive a space shuttle, I decided to pass on it...

 

ya i see what you mean, $12 per foot depending on diameter

 

McMaster is way overpriced. Take a look at the last 2 pages of this thread
