OK why not just use universal vacuum lines at Auto Parts store?

Universal vacuum line will work, but, buying the NWP blockoff plate is more fun.

Where did you get the idea that you can't?

the lines in green have this ECO< 3*1104 ----- is this number referring to size?



>ECO< 3*1104 in green

I think it's 3/16". Last time I just ripped the broken line off at the oreilly parking lot and bought some bulk hose the same size.

3/16" is 4.7625mm.
Is this inner or outer diameter?
There are usually two numbers when buying this type of vacuum line.
An inner and outer number.
3*1104 this could be 3.1104 mm - inner diameter?

Digital Calipers are nice tools but no one should need one for this.

All these cars are identical so there is only one answer

Universal is all that's available

5/32" tubing for the VIAS vacuum tubes. it's universal windshield washer tube/vacuum line.

Universal PCV hoses have to be used as replacements

there are three sizes

1. .343" or 3/8" tubing for the PCV valve to intake collector.

2. .468" for valve cover to valve cover tube

3. .593" For valve cover to air cleaner.

you could go to Nissan and pay $120 or go to local parts store and get this for under $20.

Also note that hose/pipe is measured by the ID and tubing is measured OD

PCV lines are all 1/32

I'm pretty sure the one PCV
11/32
The valve cover to valve cover is
13/32
And the bigger PCV is
19/32

The Vacuum lines seem to be about 9/64"

Nissan had to use different vacuums lines for emission purposes! The diameter of the hose dictated the amount of flow so they had to either restrict or increase the size in some areas. It has to be this way.
