.. and be sure to test that sniffle valve before install. My first one from
Superior leaked air in the "closed" position.

Regardless of what type of ignition source you have, or, which sump you
have be it a Ryton, ECI, Lycoming, or Happy Joes from Kokamoe, if the
electric boost pump is used to prime the engine, you are getting fuel in
the intake plenum, plane (only spelling I know :)and simple! That is the
reason for the drain (sniffle valve). It is important that the sniffle
valve be located in the LOWEST spot on the induction part of the system,
with the plane at it's natural resting attitude. You have to realize
that if the pump is turned on say for 5 seconds, you have to wait until
you are confident that any excess fuel in the plenum has drained before
you crank the engine. This is in my opinion the cause of the Ryton
issue.
