Blown the SAME v12-specific ABC line three times
Heads-up, the dead-end line that is attached to the ABC pump that simply turns 180 degrees and terminates is poorly made. Found only on the v12 variants.
I've yanked mine twice. First one from FCP popped in about 8 miles. Second one (Alco FCP, OEM brand) lasted slightly more than a year and once again popped.
As such, I'm custom-making a replacement. Not too bad to do once you've fixed a couple other lines in the same manner. You'll have to use orange Hydraulic line if you do this, since it dampens pump pulsations (the entire point of this line).
About $70 before shipping for two ~12" lengths of line with ends attached to JIC connectors, and the JIC to hard line attachments, etc. Line's rated to 4000 PSI, so It may be less trash than the factory line.
Merry Christmas!

Worth considering.... You are already making a line. Equip it with the pulsation dampener used for 221 and 222 cars. The one that threads into the pump.
Where you are blowing up this line... verify that system pressure is not too high.

For the new hoses, it's been the same line at the same point, the soft hose crimp closest to the pump connection. First time it partially split/frayed, this time it came off completely. Original hose had developed a pinhole in the soft line.
System pressure is OK, around 188 bar idling, 155-185 driving around (I've graphed this data with my reader a few times). All accumulators have been changed.
Just a poorly made line IMO.
