So I've searched quite a lot for this information and I'm still not finding what I need. Basically I replaced 2 brake lines on my 2000 Buick Century Limited. When trying to thread the other line into the abs pump it will not thread all the way in because the threads became trashed taking the old line out. I do not have the money for a new abs pump because they are outrageously expensive and have opted to just do a tee directly into the master cylinder and cut out the abs out entirely. Only problem is figuring out the size. I know the lines going into the pump are 3/16 M10x1.0 Bubble flare. However the fittings on the lines going from the pump to the master cylinder are slightly larger. How much larger is what I need to know. Does anyone know the size of this fitting?
