How much silicone vaccum hose do i need to change all the vaccum line in a GSL-SE???

 

I think it was the vibrant bag that i bought, and I used it all! My friends talon only used about a 1/4 of his. Thats not incuding the one under the manifoldor any other ones that i couldn't reach. Oh it was 60 bucks to.

 

man, that's like a 3rd gen, i don't think a 1st gen uses that much. I was thinking more around like 10ft or something

 

I'd say 10 ft of the 1/4 inch stuff should do all the loops and dizzy hoses on te stock emissions stuff... maybe some 3/8 inch diameter for the other, larger hoses, and some 1/2 inch for the really big ones... etc, etc... IF you want everything to match...

I believe they are metric sizes though, so more like 3.5-4mm and stuff. Oh and I was kinda wondering...If you change the overall diameter of a the hoses (say you use 3.5mm instead of 4mm), since you are basically changing the volume of the hose, wouldnt that affect the vaccum switches and stuff? Cause if the hose is smaller, its gonna hold less air, which means that it may trip sooner when the engine supplies a smaller amount of vaccum that it normally would. Does that even make sense? Or is it not that big of a deal?

that's what i wanted to here, 3-4mm 10'

No it doesn't affect the vaccum switches b/c it's vaccum, it's pressure, vaccum doesn't change by the diameter of the hose

 

i was wondering the same thing about the vacuum hoses.
Would the diameter make any diffrence when changing to a metric size?

I just priced this with hightempsilicone.com! The mini kits are $35.00 and include 15Ft of 3.5MM, 10Ft of 6MM and 2 ft of 10MM hose. My friend Hector did his whole car up and loves the stuff. i will be ordering mid winter to do this project.

I paid twenty bucks for an assortment of sizes all in one bag at Autozone. Had quite a bit left over after my rat's nest removal operation.

 

how did it run after you removed the ratsnest and changed all the vacuum hoses? just
curious.

Pressure in - losses = pressure out. Since the air in the hose is not so much flowing as it is transfering pressure, the losses are negligable.

The real concern (not that it is a concern with the small size changes here) is the fidelity of the signal. A larger diameter tube contains more air mass, and therefore is slower to react to changes in pressure. So vacuum switching may not happen at the same time as you change tube sizes.

thanks...^ this is exactly what i wanted to know. i was afraid changing from standard to metric size hoses may cause problems. but the smaller hoses ones would be ok to change just not the bigger hoses say 3/8 inch ones.
