Whereas, the worn Toyota fuel pump parts need to be repaired or replaced for better performance. Before installing a new unit, it is always best to pressure and volume test out the unit to avoid having to redo the job. You can test the volume of the fuel delivery once the system has pressurized by cranking the engine to check the flow of the fuel (disconnect the fuel line going to the carburetor and the power going to the coil). You can test the pressure out by connecting a gauge in between the fuel pump and the carburetor which will let you know how much psi of fuel is flowing. Servicing the Toyota fuel pump parts will require the tank to be drained and removed from the car.
