Q: losing fuel pressure when it warms up

asked by on

I have a older carbourated 22r swapped into my 4runner I was driving it and it started spuddering on the highway so I checked the little window on the front of the carb and it was not showing much fuel so I replaced the fuel pump and filter and the lines and I cleaned the tank out and tried to run it but once it warms up it loses fuel pressure starts and runs fine for like 10 minutes but then it loses fuel pressure so my question is what could be causing this
