abs pump module thread/pitch size..Resolved M10x1.0..
Well one of the abs lines that go into pump is cross threaded. I had changed out pumps and went to hook up the line and its leaking out everywhere. I need to re tap the pump it but don't know the thread/pitch size. Was wondering if someone could help me out. It's one of the ones that are on top like 4 of them.

Take the old BPMV to autozone and they have a selection of brass flare nuts that you can screw into a non damaged hole.
If you dont ave the old one, just purchase a bunce close to the correct size and figure out which one fits.. Return the ones that dont fit.

OP: just remember, steel tubes such as brake lines that use flare nuts (either SAE or bubble flare) have straight threads (tube-threads), not tapered threads like pipe threads.
If the flares are bubble-flare type, which I think they are, they will be Metric.

Hope it works out for ya. That's got to be a major PITA. 
If it turns out you can't get the correct sized thread-chaser or a blind-hole tap maybe, if you can at least determine the correct Metric size, you may be able to fashion your own thread chaser of sorts. Using a Dremel, cut four lengthwise slots in the threads of a bolt. Gotta be extra sure you start it straight though. I think a lot's going to depend on how far up inside the damaged threads go.
Good luck and let us know how you make out.

Some stuff to know,, The flare nut on the line DOES NOT seal anything. It forces the flare on the line up against the nipple inside the hole.
Use a jewelers file and dress the threads on the but on the brake line
If you move the nut back on the line and adjust/bend the line so that it goes into the hole STRAIGHT,, the flare gland nut will start a LOT easier.
If you cant get the store bought flare nut to start in the BPMV by hand,, you better be working on the threads inside the hole!!!!!

Item #46 in this illustration is the tube nut in question. Apparently a 10 mm x 1.0 is the size and pitch.
NUT-INV FLD TUBE RR BRK PIPE,M10X1.0X10.1 THD,17.1 TL,FOR 4.75 OD TUBE,LCS,GMW47,(ALL MODELS/ALL YEARS)
The reason both brake pipes going to the rear show to be "item 43" is because GM does not provide pre-bent brake tubing as a replacement part. Both tubes in the illustration are the same size and they will sell bulk un-bent tubing of the correct size to anyone wanting to fab up their own. They DO however, show a part number for the individual fittings on each end. It is: 11561640 in this case.

Not until Monday I didn't have the right tap but the pics you guys posted are awesome if I have to cut into it. Ill let you know when I get over there how it goes. The threads on the flared nut look fine it's the pump itself. No bueno

Btw, the letters all along the length of the long brake lines relate to the retainers that are used to secure them. They are shown at the bottom of the picture.
