My super fastbuild has 3/8" vent lines, but the original ESs had 1/4". I found this out AFTER building my wingtips with the 1/4" tubing per the manual. There was also an SB on the original tubing used in the vent lines. I had a IV in my hangar for some interior work that had a wing tank fuel leak. I had to drain the tank and wasn't sure I could keep up with the flow after taking out the quick drain. So I put a piece of duct tape over the NACA. The fuel practically stopped flowing after less than 1 gallon. That's with 35 gallons of head pressure. I'm thinking that a clogged vent would be impossible to overcome with the boost pump.
