The pumps that are mounted in the tank, we found fair worse than the ones mounted in the engine compartment. When the fuel in the tank is 1/4 to half and you make a sharp turns, the fuel sloshes to one side and runs the pump dry for a second or 2. Over time it also ruins the pump.
wouldnt this happen to a pump that is not located in the tank too? i mean regardless of pump location in a sharp turn if the fuel gets away from the pickup then the pump will cavitate. I would think the pump would have a harder time regaining prime the farther it is away from the fuel source. All modern fuel injected cars have their pumps in the tanks and I have never heard of problems in cornering situations
