I would if you wouldn't cost too much money.
The intake pumps are better because it is submersed and basically gravity fed so the pump has to do less work and does not have to pull a vacuum. The pressure head at the inlet pump will be positive, density of gas X gravity constant X height of fuel above the pump.
The internal pump will have to pull a vacuum on the suction side. Theoretically, if you mounted the pump below the pickup in the tank then it would siphon to the pump once you got the pump primed. But since the fuel is in a vacuum, it is going to vaporize at a lower temperature and you could lose fuel. This was happening to me in Texas and at higher altitiudes in the mountains. The engine would die, and I would have to wait till the fuel before the pump cooled so the pump could move fuel again.
The cons of an in tank pump is if it fails, you have to pull the tank to change it, but all new gas vehicles with efi have in tank pumps as far as I know. I also know my diesel has a pump on the frame rail but that has its own problems and also has a much higher vaporization temperature than gasoline.
I am actually looking into modifying my existing tank for an in tank pump.
