I did a search and found a topic about it but there was only one reply and it didnt seem to definite.

Im gonna be running a foam filled fuel cell, and I have blocked off my OMP will I have any problems premixing with all the foam in the fuel cell. I was kinda thinking the foam may kinda filter the oil out of the gas before it gets sent too the engine?

 

The oil mixes with the gas and will not be filtered out. Most people racing rotaries pre-mix and run fuel cells as I do. I'm not aware of it ever being a problem.

 

yea im new to this whole premixing or rotary thing. It just came up in my mind the other day. Thanks for the response.
