Being convinced I can find new ones without the usual $7.00/1 week shipping charge, I came here asking for help. Im new at measuring threads. Using my gauge, I get this:
Thread diameter: M8 (my micrometer measured 7.89mm)
Thread type: 1.25
Thread height: 10mm
If this is correct, I think I found a replacement for $4.00 with one day shipping, here:

@DS,
I can't help you with your question other than obliquely when I got my HEL lines made up I also bought a stainless steel brake bleed screw but I couldn't install it because the pitch was wrong. So it would appear that whatever the pitch is it wasn't the normal pitch.
FYI, this is good, 8mm M8 x 1.25mm is correct. I went with a Lefossi part from Amazon Prime, $3.99!
Suzies are notorious for having different threads at each end of the brake line. Proceed with caution and appropiate observation.
Just checked front vs back and they're both M8 x 1.25
