I have an amtrol rp-15 that is 17 years old and the the tank with it got water logged. The pump sits on top of the tank and feeds the water directly in the top. The new tank I got is plumbed on the bottom so I just offset the pump so I could could pipe straight down to the bottom of the tank. My question is when I tried to screw in the male adapter it would only go in one thread. The threads on the pump looks pretty fine. Is there a male adapter with fine threads because i can't find one anywhere?

NPT threads are standard in the US. If you got a tank with Euro threads they are completely different. If the tank is suppose to have NPT threads, then either the treads in the tank or the male adapter is bad. BTW, the bladder in your tank failed from the pump cycling on and off too much. Using a Cycle Stop Valve to stop the pump from cycling will make the tank, pump, pressure switch, check valve, etc, last longer. Plus you will really like the strong constant pressure in the house compared to the 40 to 60 swings you get when the pump is cycling on and off.

Your problem is not connecting to the pressure tank, but is connecting to the pump, right?
What is your pump?
That is correct.
The pump is an Amtrol rp-15
I have considered that after doing some research on it.
Sorry. When I saw Amtrol, I incorrectly presumed that was just the pressure tank. https://www.amtrol.com/wp-content/uploads/2017/06/9040B140_07_14_Pressuriser_IO.pdf
Could you adapt the old connection ?
