The systems are very different. K(onstant) type, A/K/A CIS (constant injection system) uses a fuel distributor operated by a machanical airflow meter mounted on the air filter housing. There is a separate fuel hose to each injector. This system also uses a rectangular aluminum temperature-sensing pressure regulator (warm-up valve) bolted to the engine block.
L, the electical symbol for loopstick (magnetic coil), uses a common fuel pipe and a two-wire connector that allows the electronics to control fuel delivery.
