I have ran my new fuel lines (-8 feed and -6 return) and tried using the stock vent but it is not working out. I also sumped my stock tank and have an external Magna Fuel 625 pump, prefilter and after filter. I have done a few searches and have not found much info on this. What are you guys doing for your vent? I thought I was having problems with my new fuel pump but while I was draining the tank through the sump it would almost stop until I would loosen up the gas cap to vent it out. If I would tighten the cap back up I could here the air in the tank and it would slow to almost a stop again. Since I am not using the stock pump I have thought about modifying the feed and or the return tube to be a vent for the tank but didn't know if this would work or not. Any help in this area would be a great help.
Thanks,
