Hi Matt,

5.3 standard cab, 8'bed 4wd 4wabs. The three female outlets on top of the abs pump(located under the drivers seat on the frame)are literally outlets. The bottom two are inlets from the master cylinder. I took the lines off six months ago never dreaming no one made them. Now that I finally found the lines(cnc bent etc.).

I've forgotten which of the two lower orifices in the abs module are for the front master cylinder brake line in to the module,obviously which ever is for the front the other is for the rear.And I'm aware the rear line on the master cylinder is the front brakes.which hole in the abs is for the front master cylinder output line(line in to abs module).

Sorry it took me a few. I had to run out to my own truck to answer your question since I could not find a diagram from GM..

Here is a picture showing which line is which.

Exactly what I needed! I'm a certified master mechanic with 40 years in the business. Lately I have retired and have been restoring older GM junk. Camaros, Vettes etc. I've been doing this all my life,switched from mechanical to paint and body to learn how to do it(isn't that how everyone got started?). If you need any info on older 65-80 Chevy stuff you can contact me.

If you are going to to give an email you have to code it a little bit, but I am a very big Corvette fan here are some pics of mine or find me mttjones 55 at aol but be com.
