So i hooked up my fuel gauge to check my fuel pressure the other day to the schrader valve on the fuel rail. I started the car and when i checked the gauge it read 15 lbs. WAY wrong. So i looked over at the schrader valve and saw fuel leaking out of it, so i quickly turned the car off and cleaned up the spilled fuel. I tried multiple times after that, making sure the gauge was not cross threaded and made sure it was tight, but each time the schrader valve was leaking. Is there anything i can do to fix it so i can check my fuel pressure at idle and WOT? Thanks alot

You removed the schrader valve before you hooked up the gauge, right ?
If you did not that is why your readings are not correct.

That doesn't account for the leak....
OP, check to see if the sealing face of the rail fitting is scarred up.

and i dont see what the schrader in the rail has to do with the leak when running a fuel gauge , if you attach a connector for the gauge the schrader is out of the picture as a source of a leak
the schrader valve is the small insert threaded inside the end of the fuel rail
if the schrader is bad you can replace it with one from a tire valve stem . ..
the fuel test port at the rail has threads on the outside and they are -4AN and you shouldnt leave an open schrader on the rail , there is a fuel rail cap that should be installed
if the gauge connector doesnt have a schrader depressor you need to remove the schrader from the rail to have the gauge work
now that you know that the rail is -4an the gauge connector must also be -4AN . if you are trying to thread any other fitting to the rail it will leak , and AN doesntneed sealer or tape so dont use any
if its leaking with the gauge connected either the flared end of the rail is defective or the gauge connector is defective or cracked.
