Thank you Zachary17! The pump specialist called today and said that the fuel screw was really small and the pump has something broken but I don't remember what. Hopefully new parts can be found in the pump. The repair will be quite expensive but hopefully it will be good.
The intake manifold is original, but other parts should get more power.
