Hi all:
First off, many thanks to the responses to my posts re my "thar she blows" IP delivery valves.
As a refresher, my IP is dropping fuel everywhere (and, yes, it is parked in the street now

) and it appeared that an IP stud was stripped. Based on the presence of "different" washers and nuts, it's clear that the PO messed around a bit...
But now for the good news! The IP stud is _not_ stripped! I painted 'er up with some fine pink nail polish, gave a turn, and sure enough ... the stud is holding firm.
So instead of a rebuilt IP, I've got some new nuts, the seals are in the mail and I can breathe again

.
Thanks again to everyone who chimed in!
Happy dieseling;
