Good point on the venting. The gas caps that are sold today as vented really aren't like those of old. They only vent one way. For FI, it should vent both ways if there isn't a separate unrestricted vent line. Thank all the emission controls vapor recovery systems for this fact. I had to break out the check valve in my "vented" cap so it would vent both ways. If you have what is called an anti rollover thing in the top of the tank, mine was just a piece of Heloise mesh which would vent both ways. I made it into a return line plate so I needed a gas cap that actually vented both ways.
