vacuum hoses connected to fuel injectors?!?

Another point to the above pic...that would also not be a proper design because the air from the crankcase would be introduced to the engine, unmetered. It is on purpase that the PCV system takes air after the filter and sensor, but before the TB. Air diverted into the crankcase should nearly equal air coming out and into the manifold to ensure all the air going in the engine is accurately accounted for.
