Can't find anything linking a lt1 to a ls fead setup but it looks like it would or could clear a vacuum pump.

No, the vacuum pump was not retained as it won't physically fit in most LS swap applications. The pump is only used in truck applications to augment the vacuum signal when the engine is operating in cylinder deactivation mode, so if will not be needed by someone that is not interested in utilizing that function in their swap.
