intank or inline fuel pump?

[LX5liter]

[i] The side of the pump that pulls the fuel creates a low pressure zone between it and the fuel, whereas the side of the pump that is pushed creates a high pressure zone, which eliminates the possibility of vapor lock. So, logic dictates that you want the pulling side to be as short as possible, and the pushing side to be the longest. You can't get much closer to the fuel than in the tank.

Like we say in the Heavy Duty trade; Pumps don't suck, they push!
