When converting a fuel pump from two pipe to one pipe, what component must be removed?

In the process of converting a fuel pump from a two-pipe system to a one-pipe system, the component that must be removed is the bypass plug. In a two-pipe system, the bypass plug is used to allow for fuel returning to the tank, which is not necessary in a one-pipe system where fuel is pulled from the tank and returned through the same line. Removing the bypass plug effectively redirects the flow and enables the proper operation of the one-pipe configuration.

Maintaining the proper configuration is essential for achieving optimal performance and efficiency in the fuel system.
