Leaking VE pump where to find parts

[Hyperpack]

My old 92 has a dripping VE pump, I think it is leaking from plug #130 on the distributor end of the pump, Where do I find oring #129 before I take it apart?
What will fall/jump out when I remove this plug?
I think I can get the plug out without removing pump or lines. Is this new fuel eating up the seals in my trusty old truck and is this just the first leak I will be dealing with in the next few thousand miles?
Thanks

The BOSCH seal kit is DGK121, I got mine on eBay a couple months back. Mine was leaking at the KSB plug, o-rings were brittle. Don't know what will jump out, get a schematic and a dental mirror.
