plugging the vick
I usually don't plug the vent when in storage, but I just got one of the plugs that screw in and close the vent in an airplane. When working on the fuel system I pressure tested my tank, rinsed it out with a little denatured alcohol, then rinsed it again with a little diesel fuel a couple of times (I guess I did not get all the fuel out on that second rinse). Well I put the fuel tank in and connected the vent, connected the pickup to the uat, and then put all the lines on the uat. I plugged the vent but not the fill line from the uat. The pressure that built up in the tank had enough pressure to push the fuel up the pickup and into the uat (about an ounce). So if there is enough pressure to do that I will not be closing my vent for long periods of time. I will close them from the field to home, but I will either remove the vent plug or open the vent line on the uat so that pressure can escape.
