Is it 3/16"? Just want to confirm that it's right. From searching part stores with my vehicle model this is what I come up with but I find it odd that it's in imperial and not metric.

90' 22re

 

3/16" is easier then 4.75 mm .

just make sure it has the correct M10x1.0 nuts

 

MAKE SURE THAT YOU USE M10x1.0 INVERTED FLARE NUTS!!! There is a standard nut (not sure of the size) that WILL thread into M10x1.0 threads but WILL NOT work - you can hardly tell the difference between the two. There is also a M10x1.0 bubble flare nut that looks similar but WILL NOT work either. Napa does have brakelines up to 72" that are pre-flared. Use your original lines as a template to bend new ones and replace a section. I know at Napa they are labeled "JAPANESE" and I'm fairly certain that they don't even have the flarenut sizes on the label.

 

What lines are you trying to replace anyway?

 

Right side of the tee is leaking. Most likely will have to cut it all out
