At this time, I'm committed to using the FFR tank and have been reading about the many shortcomings including poor venting. I have the later style tank and am currently modifying the '06 fuel pump and level sensor. Part of this includes making a vent out of one of the tubes. I was wondering if enlarging the vent might help with the filling of the tank. Seems to me you could tap a larger fitting in the place where it will vent. Maybe a barbed fitting either tapped and well sealed into the plate or even with a lock nut on the inside and well sealed. Would effectively double the size of the vent.

Thoughts???

Thanks, Robert.
