Geoff- The purge mode flushes back through the supply line all the way to the VO tank. Ran it that way for 5 minutes and still not burning any grease.

Dan-that return loop sounds good. Are the "T's" available at auto supply stores?

I have photos to post, but don't know how. Anybody point me to a link?
