Are the brake lines on Nissans 10mmX1.0? anyone know where you can get a 10mm X 1.0 to 1/8" NPT?

I believe so. Speed shops can special order them...I got mine at Lopers here in Mesa.

Check with Foothill Offroad. If it's not on the web site, give them a call.

I believe what you need is Weatherhead part number 1480 or 1442. Ask your Napa dealer if they carry the full line of weathead fittings. If you google weatherhead you will find the file with all the fittings listed. Toyota uses the same 10mm fittings, and in my case I just bought standard aftermarket Yota to d44 conversion lines and stuff.

Check that, it's a 1443, I think.

I should rephrase female 10mm x 1.0 to male 1/8" NPT

Come on now, I gave you the part number, the company name, and where to buy it, what else do you need? I have a couple here, I guess I could send you one, but try Napa first, that's where I got mine.

I'm getting ready to do an sas on my truck and found the brakewarehouse.com can make custom lines and they have every fitting imaginable. There website isn't the greatest but you can call them and they will be able to get you exactly what you need. They are super easy to deal with, i recommend talking with Robert.
