Working from memory--so could be wrong--but even the new SUs with the 0-ring 
still use fiber washers next to the banjo bolt head.  Did you replace these?  
If not, try new--they "crush" to form a seal and usually aren't reusable (maybe 
in a pinch).  Tighten pretty tight, but remember the pump housing is aluminum 
and can be cross-threaded or cracked by the steel banjo bolt.  Re-tighten after 
a few hours of operation.  Also make sure you didn't munge the o-rings.

You measured 12V because there's 12V potential, but the harness wire was 
limiting current (in effect, acting like a resistor).
