I can't keep fuel pressure after leaving the car sitting for a little while. I think I found the issue. The rear connection from the fuel line to the rail, if you wiggle the connector fuel will drip out of it which is where I think I'm losing fuel pressure. If I turn the key to ON and let it prime and then start it will have no issue. If I go directly to START without letting it prime at all, it will give me a very long crank as it's building pressure.
The leak is most concerning, it doesn't leak unless I move it, but that is still a fire hazard. Are there orings I can replace in these lines/connectors??

me and you both lol but I have no visual leaks, theres an oring from the FPR to the rails but I do not remember there being one to the return line, it just screws in. You should try tightening the connector first
If the Injectors are not leaking . it might well be the O ring on the Fuel inlet connector. Seems many develope a slight leak around the o ring in the connector. This has been asked and answered several times .
but basically .. You can get the "o" rings at Autozone or other places in a variety pack for $7. Dig out the old o ring and replace it. ( my favored solution)
or do like others and Cut the fuel connector off and clamp in a replacement connector . ( not my favorite idea)
