Fuel leak from top of gear pump head

[SquareOne]

So, after 4 days, 3 stops and about a 250mi round trip, I finally have all the pieces for this damn thing. Here are the part numbers for future reference:

4384373RX - Fuel pump head assembly (reman unfortunately) - (x1)
3046599 - FP 12pt cap screw, long (what's 30 bucks for fresh bolts) - (x1)
3946085 - FP 12pt cap screw, short - (x3)
2872513 - FP head gasket - (x1)
3963990 - Sealing washer for Banjo bolt - (x2)
3963988 - Sealing washer for Banjo bolt - (x2)
2872663 - Gasket (for fuel pump adapter at rear of head) - (x1)

All in, looking at about $2130 in parts. The fuel pump head comes as an assembly with the barrel/plunger assemblies as well as the high pressure fuel fitting (at front of head) already installed.

I'll be installing tomorrow morning and report back with the results. Hopefully there aren't any surprises.

Got it cleaned up and shot a few coats of Cummins red. Here is a couple pics of how they come, minus the blue tape.
