The sniffle valves are not blue or 90 deg.  This must be a Lancair part.  
You only need a check/sniffle valve for the cylinder drains.  It is common 
practice to tee the cylinder drains together.  The cylinder drains allow 
excess fuel out of the intake port when the engine is primed with the 
electric boost pump during starting.  The check feature prevents air from 
being drawn back into the intake port when the manifold pressure is below 
ambient, which is any time the engine is running.  The manifold and fuel 
pump seal drains can be joined but should be routed separately from the 
cylinder drains.  The seal drains may also have a duck-bill or similar 
feature to keep dirt and moisture out.
