RE: Fuel leak from top of gear pump head
I was afraid of the one time 'crush fit' as well, and my assumption is 'blank stares' if I ask the local Cummins store about purchasing (or even locating for that matter) a replacement. I'll do some research on the thread pitch/size in order to get the correct torque. There was no sealant or other product used on the threads so once the initial break, it literally came out with 2 fingers.

I'm going to inspect the threads within the head as well once the weather calms down to see if they are compromised. Looks like I'll be putting a head on it if this removal and re-torque doesn't work. I almost bought an entire head assembly with the last rebuild, just for the hell of it....

** Plug is a 3/4" Diameter with 16tpi. There is 7/16" of threaded surface. It is steel, but don't know the grade.
