Hi Walter

Most all using the plastic tanks are using 2 differant types of venting
1 being uniflow with the uniflow vent attached to the fuel pick tube with thin flexible tubing or 2 tubes to the back. one uniflow and 1 pickup
The other venting scheme is for the uniflow vent to curve back from the front of the tank to the front inside top position, not really uniflow but it seems to work well for people. It gets the vent uncovered almost instantly and stopped the  mid flight setp up ( in speed)  that occurrs in a lot of plastic tanks.
