no start
In the left side; standpipe, dummy plug, nipple cup o-rings and injector seals half way down and the top seal... that's it. You pulled the stand pipe and put a dummy plug in the hole and it stopped... that right?
Yes it stopped

So the standpipe allows oil into the rail and the dummy plug is there because the rails are for either side. Nipple cups are next, injector top seals and finely injectors.
With two plugs in place, no air was allowed into the rail, makes sense to hear no air... but with everything in place like it's supposed to be and the only air you heard was at the standpipe area... which is supposed to feed a rail.... yours was feeding the valve cover and the oil fill tube?
Even though it looked good visually?
You following me ......???...???

let's see
passenger side air leak
feed air into icp port
standpipe area leak
replace standpipe with dummy plug no leak
bad standpipe
= bad 2 month old standpipe for whatever reason
haven't slept great in a year so forgive if I don't see something blaring obvious
but am I close?
Yes, I think you have a bad stand pipe. Torque spec is 60lbs. You plugged it with a dummy plug and it stopped, if it didn't leak, it wouldn't put air thru the valve cover or the oil fill tube unless it was an injector or a nipple cup.
with the old standpipe and shop air in the icp still getting a leak down low in the area of the standpipe.
could my branch tube be bad? any way to isolate that? how much of a pita is it to replace the branch tube?

ok
put the used updated standpipe in. yup still leaks. however when I took it out this time, the 2 halfs were not tight to each other. maybe 1/8" gap. I don't think they pulled apart during removal as it came right out this time. put a glob of vaseline on the joint and the bottom of the standpipe and reinstalled. put air to it closed the ipr. removed it and the vaseline on the bottom looks like it has been blown away in 1 section.
another thing I noticed when the bottom half stays in I use a tap to remove it. I tap the tap so it will bite and it goes in about the 1/8" I saw between the halves.
I did notice a slight change in the air sound when I activate the ipr.
It seems like I have a leak at the standpipe branch tube junction.
please talk me of the ledge...

pulled the drivers side. same thing as other side. air leak down low near standpipe. slight tone change when ipr is closed. sounds like there is more air coming out of the standpipe area when the ipr is closed.
is it possible my new pump is *****?

Are you triple dog sure you did not switch the two o-rings around when you installed the pump? The sound of a leak can migrate down to the branch tube area, for sure. A bad STC on a later build can sound like a leak somewhere else with the HPOP cover on for example.
If the two o-rings are switched around, it will start and run great, but won't last that long. It's happened before.
I highly doubt the pump is bad.......if this was a Ford reman it would be another story.
The odds of the branch tube being bad are not in your favor thankfully, and it's a big job.
I'm still betting those o-rings are your issue. Branch tube require the engine or tranny to come out. Casey drove his truck about a week, then is started again. He went after the pump first, found the o-ring chewed up. But was hearing leaks under the covers.
