My right wing tip is slightly lower than my left wingtip when parked on a level surface. Plane has always been this way so I never gave it much thought.

Went out today to do some minor MX and I fired up the engines afterwards. Engines ran fine, but I noticed my front(left) tank was reading EMPTY and my right (rear) tank was reading FULL.

When I parked the plane a few weeks ago it had half tanks in both wings.

Fuel selectors are both in the normal position. I generally don't touch them.

I shook the wings and heard very little splashing on the left side, but the right side sounded full. So I'm assuming the fuel gravity flowed from the left wing to the right wing.

Looking at the fuel system, the only interconnects are the fuel selector valves. Is it possible that I have a leaky fuel selector valve that is allowing fuel to gravity transfer between tanks?

If this is the case, I'm afraid to fill the left side as it may just drain out the vents on the right side.

Should I be turning off the fuel selectors after each flight?

Anybody have any wisdom to share?
