I just got this back from the Smoke Daddy people. Sounds like FE has heard of them.
"Hi Larry
I have had the same question from another FEC100 owner. I suggest The Big Kahuna with the rheostat pump. If you call Fast Eddy I hear this is the one he is also suggesting. I would also like a picture of the Smoke Daddy attached to the FEC100
Thanks'
