I would say you would need a larger vent than what you described. I had my fuel cell out last week and removed the fitting for the return welded to the top of the cell and replaced it with a bulked fitting with an anti aeration tube inside about 1.75" from the bottom of the cell. I have a -8 vent on the other side.
Good move on the return fitting inside your cell, things like that make a difference.
OP needs at least a #8 size for a vent if your gonna vent the tank properly at the end of a quarter mile.

its not the vent. WHAT NOW?
yes, the pump is lower than the cell. actually the pump wasnt lower than the tank in the challenger and it worked great
as soon as i start drving it the pressure starts going down to nothing. if i go crack the line in front or behind the pump it works again [Edited by Moparts - Family Friendly Site - Keep it clean]!!!!!!??????
