The size of the lines may vary by where on the truck they are located.Most are 3/16".If you take a piece of the metal line and a fitting from the line you will obtain the correct part.Compression fittings should never be used on brake lines,in most states it is illegal to use them.You should buy unions and attach two lines together that way for optimum safety.If you need more help please ask,if my answer has helped please click on my accept button.Thank you very much.
