FYI:

Old style housing PN which is stamped on the casting (as in photo above):
615 092 01 08

New style housing PN (# in same spot):
615 092 02 08 <- only the '02' is different

That'll make your junkyard search easy. After 1 minute of looking, you will be able to spot them ten feet away because the new style has a bigger bolt

alas, the subtleties of really getting to know these cars...

Yes, that is the same stuff, available by the foot or meter, that "jumps" between the injectors.
The last one has a plug in the end.
It is a routine replacement item, they just push on and pull off. You have a hard time removing the old ones, be careful to not nick the nipples on the injectors. When putting on new lines, I dip the ends in oil to facilitate installation.

No one mentioned it, but the old style filter bolt that uses the crush washer also has a single o-ring on its shaft. You will need to replace this o-ring as well. The crush washer can generally be used 2x by flipping it over after the first filter change.
