Vacuum lines

Post by jsloden »

I am going to be replacing the pcv system within the next week. I was also looking at replacing ALL of the vacuum lines at the same time. Can anyone tell me roughly how many feet of vacuum line I will need to do the whole job. I am ordering the three turbo vacuum lines from IPD along with the elbow kit so that's covered. There are still a lot of them though. And are there different sizes? Car is a 98 c70 hpt coupe.

I just ordered 3mm, 6mm and 10mm diameter from this company https://www.amazon.com/gp/aw/d/B008N0VT3Q

The default length is 10 feet with them which will be way more than enough. Though I’ve found there are many automotive uses for silicone vacuum hose and it isn’t bad to have some leftover.

Probably 8-10 ft of 3mm, 5-6 of 6 or 8 mm and 2-3 ft of 10 or 12mm would do it.

And don’t forget clamps. And carb cleaner to check for vac leaks when you’re done
