One downside to installing the spring inside the fuel pump pickup hose is the fact that the spring may rust. Small particles of rust will damage the fuel pump. The fuel filter should catch the rust particles before they make it to the engine or fuel distributor.

There is no downside to installing a spring, it is a cheap solution.
