What is the average range of pressure for fuel pump from the tank in a fuel injection system?
Fuel Injection Engines Engines with fuel injection will normally use electric fuel pumps to supply the higher pressure demanded by the system. With port injection, the required pressure ranges from 45 psi to 66 psi. On throttle body injection (TBI) systems, the pressure is normally between 9 psi to 18 psi.

Can a fuel pump be too powerful?
Using the wrong fuel pump that delivers excess pressure can cause problems ranging from poor performance and lower gas mileage to flooding and carburetor damage. When the pressure is only a little over the required amount, your vehicle may sputter when you first accelerate from a stopped position.
How do you know if you have low fuel pressure?
The most common symptom of low fuel pressure is an unresponsive throttle or a stalling engine. You may also notice signs like difficulty starting the car, a check engine light on the dashboard, misfires, or low performance.
