Anyone know the part number to the brake line shown coming out of the left side of this master cylinder and going to the proportioning valve? No parts stores have anything that will fit. I tried the local Acura dealer and they were totally unhelpful. For some reason that flare nut is larger than ther rest, and it looks like I just have to order the entire line to get the nut. Its a 96 integra 3 door with abs.

Thanks to Andy for his help and the attached pic.
