Also, Dirk from Pacific RC literally said with my 235 (don't go crazy with that 8mm stuff)

Yep, thought of all that, just peace of mind for me, never heard of a problem using too big of fuel line, and my UAT is already plumbed for that size as well as my overflow vent. Thanks again for your input, I appreciate it.
