I bought my plane earlier this week and got out to go flying this evening. When pushing back after landing I noticed it was dripping fuel out of a small drain just on the pilot's side of the nose gear doors. It was pretty steady at about a drip every second or two. If I turn the fuel selector to "OFF" it will stop, otherwise it continues to drip. It didn't do this on Monday when the seller and I flew it 3.1 hours total and it wasn't dripping at all during the inspection. If I turn the boost pump on it sputters and streams out. That drain (In the picture attached it is the one circled in red) is coming right out of the electric boost pump. The green circle is around the drain that you can actuate next to the fuel selector; that one is fine.
Any ideas on what I can do other than just take it in and have the pump overhauled or replaced? Is this fairly common?
Bummer that my plane is grounded on the first week.
