Below the injector lines, are the delivery valve unions serrated? or
are they hex? Serrated have orings. Hex do not. (in my experience,
limited to 80, 81 and 83 616 engines.)
So I hear conflicting opinions about delivery valve seals. Some say
not to change them if there is no apparent leak at the IP below the
fitting. In my case there is no leak.

Yes - I forgot about delivery valve seals - those would cause poor idling.

In neither Gump nor the 95 E300D have leaking delivery valves had an
effect on starting. The primer pump did issue with getting fuel to the IP
in Gump. The leakage was really obvious though, so there was no real
mystery about there being a leak.

Could the pump plunger thing- can't remember it's name spills fluid
when I pump it. Could this be creating an air leak that would result in
stumbling and stalling?
The hand pump could indeed be creating an air leak.
