Do I need to gut the fuel pump in the tank now on a 90 ranger im gonna run a carb an mechanic fuel pump or will it be able to draw enough fuel to feed a stock 5.0 without dropping the tank and gutting it into a pickup tube and return line?

A 90 has a single high pressure pump.
Also a carb is likely gonna give you headaches at inspection time.
If you have the two pump setup yes you can just use the in tank pump to feed a carb. A regulator with a gauge would be a good idea though.
A mechanical pump won't fit on most swaps which is a pretty good sized con.
Its obd1 in pa and its a visual inspection so as long as it has an egr valve which thats all the ranger has now it can be accomplished with that plate that sits under the carb for an egr on a 80's mustang it'll pass even though it doesn't necessarily work. Haha
I was going by info on one of the tech fourms on here that said if you use a 70 econoline van pump (built upside down) it would fit. But the original plan was the pressure regulator with a bypass going from 40psi to like 5-7 psi
Yes, thank you for explaining PA's visual emissions inspections to me, since I am a licensed emissions inspector for the state of Pennsylvania.
It will ask about the EGR, the PCV, the evap system, the cat, AIR system and the heated air/fuel ration sensor. It's been a while since I did a visual only but I believe there is also an "other" category.
The standard is passing on the visual is if the original types of emissions control equipment are present and appear to be functioning. If someone brought me a vehicle that rolled off the line with EFI but had been swapped to a carb at the very least I am going to check "No" to the AF sensor, because a carb isn't doing anything with an oxygen sensor, which means said O2 sensor does not appear to be functioning. If I am correct about the "other" category I would fail it there too as I consider the MAF, and other sensors used in calculating the air/fuel ratio, as well as the injection system itself to part of the emissions controls.
Any honest inspector will fail it, even on a visual only inspection, so be prepared to keep it under 5K miles a year. And you can get away from it by moving the registration to a non-emissions county, since then you have the 42 county enhanced safety inspection, which asks the same questions and doesn't give you a 5K mile exemption option.
