1633 Threw a P0190 which is a fuel code and a P0193 which i have no idea what it is. i believe its leaning out at high RPMS for some reason.

So the fuel is getting hot???

and about the pump, its the focus fuel pump, and it threw that code only if i take the car to 5750RPMs. maybe i need a higher flowing more pressure pump.

Do you have a BAP on top of the Focus? If not, I'd bet you're maxing it out. Have you datalogged the car to see what your pump duty cycle is?

Get the pump to quit maxing and your fuel may not get heated when it goes through the pump.
