What have people done to vent the gas tank compared to the factory setup? I'm running E85 w/ 80lb injectors maxed out (100% DC @ 21psi) and want to make absolutely sure the fuel pump isn't struggling because the tank is being put in vacuum. The pump is the walbro 450, racetronix hanger, hotwire kit, and -8 feed, -6 return lines, plus a volt booster that jumps the system to 15V. Trying to optimize what I have.
I have the original gas cap and factory vent line w/ a carb fuel filter on the end of it. I can blow through it, but that's not a lot of pressure or flow.
How about just putting a loop in the rubber line coming off the top of the hanger with a little filter on it?
