Does anyone know if you have to remove the internal fuel pump from the gas tank when you install a low pressure external pump?
The internal pump produces approx 45 - 47 psi for fuel injection applications, I have Weber Carbs and am installing a low pressure external Facet Fuel pump that produces 4 - 5.5 psi along with a pressure regulator and fuel pressure gauge to monitor the level and wonder if, with the other pump disabled, will the external pump pull fuel through the disabled pump or do I need to remove the high pressure pump from the tank for proper flow?
Thanks,
Scott
