So one problem after the other.
Once I got the oil issue squared away, I prepped the car to get fuel pressure setup.
Put the fuses back in and turned the car on to accessories and checked my FPR. Didn't move at all. I heard some bubbling so I checked for leaks. Didn't see any at the time. But could smell fuel. Checked the hardlines on my firewall and under the car. There were no leaks.
Checked where my injectors are and yep...
It looks to be coming from my secondary injectors but I haven't got a good enough look to see my primaries.
Any suggestions? here are some videos, it seems to be leaking from the actual injector clips? I'm guessing that has to mean that it's coming from the top of the injector?

If it's leaking out of the clip then that means the injector body has a failure point somewhere. Can you unclip and see if it's coming out through the body? It may have traveled past the o-rings and then when the fuel hits the junction in the connector, it starts dripping.
If it's just the o-ring, get new ones and dip into engine oil before inserting into the manifold. KY jelly for injectors.

I found the problem we think. Pretty sure it's just the secondary injectors from what we saw so we took the fuel feed line, hooked it into the secondary rail, took the return line and hooked it to the other side of the rail. We sat the injectors a little higher than usual. The metalic O-rings that are within the LIM do not seat all the way to the bottom, so the o-ring of the injector was in that little gap which created no seal.
We put the injectors in know that it wasn't pushed down all the way, turn the car onto the accessories and no leaks! Double checked to make sure it was getting fuel by lifting pushing the injectors down and yep, fuel started coming out.
Went to local hardware and bought a spacer for the secondary rail to mount a little higher than usual.
Re-wiring the injector clips right now since they were pretty poorly done by us the first time.
Going to get it all back together and hope for a fuel pressure reading on the FPR this time and no leaks on the injectors.
