Question about gas tank vents 4 vs. 1

Thanks Highwaystar for the reply,
Thanks for telling me about the vent line on yours going to the engine bay. I was about to go and rip it out. I think I'll leave it in for now. I may need it.

Any other replies would greatly help on this matter. I would like to just run the fuel line up to the motor and have the vent in the back to where ever. I have a set up like that in my Demon Braket racer. I just want to be sure.
Thanks again
