Wanted to confirm the main vacuum hose sizes, maybe somewhere in the ROM or parts guide that I missed....

1. 2mm ID x 4mm OD - black with yellow stripe
2. 2mm ID x 6mm OD - black fabric wrapped
3. 4mm ID x 7mm OD - black with white stripe
4. 4mm ID x 8mm OD - black with orange/peach stripe
5. 6/7mm ID x 14/15mm OD - black, some looks reinforced others not

#1 - black with yellow



#2 - fabric



#3 - black with white




#4 - black with orange/peach




#5 - black

 

Many thx for these specs. I am trying to get my 92 6cyl C/C working and suspect vacuum lines. This will help if someone knows if the sizes are available at the usual aftermarket stores or not?

 

The black fabric one is actually 3mm or so. Typo in my part

 

Whats the purpose of fabric? I should probably redo my lines they're original

 

I recommend buying silicone vac pipes as replacements Also, if you have the GM400 gearbox, replace the vac modulator vacuum pipe too. The gearbox is far more responsive with a good vac pipe, and silicone is far more heat resistant.
