I've had a Facet pump mounted in the engine compartment of my 911 for decades.
Most of my problems ended when I mounted a large fuel filter in line with my Webers.

I have never had a problem with fuel delivery, even to the point of almost collapsing my gas tank on one occasion.

I just finished a day of autocrossing and my carbs never ran out of fuel.

Before you relocate your pump you might want to check for crimped or blocked fuel lines or debris (ie rust) in the gas tank. Also make sure you have an adequate vent on your gas tank.
