Gas tank vent help

I need some help figuring out how to vent my gas tank setup. I will be using a LS motor. Any ideas?
Do i have to vent the gas neck filler and the tank? Can i vent just one of the two?
For the vent on the sending unit, where do i run the hose to?

Re: Gas tank vent help

I ran the larger vent tube to the gas filler neck vent tube. That little vent tube I capped off...but I think you could run it to a vacuum/charcoal canister.
