the gas tank is divided into 2 halves, bridged only at the top. once fuel goes to the driver side, the only way to get it back to the passenger side is to either slosh it back with a hard left turn, or wait for the fuel pump module's secondary function of in-tank transfer to slowly pull it back. however, if fuel pressure drops, the module cannot transfer it back because the siphon is powered by fuel pressure.

A larger fuel pump than the engine needs might aid to some *slightly* measurable amount. This is because a greater return volume and higher bypass fuel pressure can boost the venturi's vacuum a little and speed up the fuel recovery time. This would not do anything to prevent the sloshing away. But it could increase the volume of fuel around the pump before it sloshes and help it collect some more fuel before the next turn. I wouldn't do a pump upgrade looking for any results, but I would try and see if I notice a difference after making a change for other reasons. My S2E fuel system which optionally has the installer physically remove the factory filter from inside the fuel pump module may help a little by increasing usable displacement inside the open lid surge canister that is integrated into the pump module. Not sure if its measurable either. |
