Fuel pumps for carburated vehicles typically put out less than 1 psi, typically around .25 psi. Just enough to get the fuel into the fuel bowl. The pressure needs to be small so that the float assembly can shut off flow when the bowl is full. The typical fuel pressure may not be relevant to your vehicle. Yours may require higher fuel pump pressure but not typically.
