Dear subscribers,

I noticed a phenomena on my 4P that I thought might = be worth sharing to see if it is unique or may be others experienced someth= ing similar:

When my ball is significantly out of center over a l= onger period of time (>30 sec), my fuel selector is on left, and I have = less than 15 gals in my left tank my engine will quit due to fuel starvatio= n.

It happens mainly when I am practicing approaches: o= n the missed go around, when I am busy applying power, getting gears and fl= aps up, selecting my next way point in the GPS, changing my approach plates= =85 if I am on the left tank with low fuel and I forget to retrim the rudder for the changed power setting my en= gine will shut down due to fuel starvation. My fuel indicator will then sho= w zero for the left tank. Switching the tanks and applying high boost bring= s it back to life within seconds. After 30 seconds or so I can see the original amount of fuel again in the = left tank. It is not a big deal anymore because I know how to fix it but it= certainly caught my full attention the first time.

In climb with full fuel I can also notice that I am = loosing fuel out of the left vent on the wing tip if I don=92t keep my ball= in the middle.

In straight and level flight I can run this tank dry= with the exact amount of unusable fuel to which I calibrated my fuel indic= ator on the ground.

The only explanation that I have for this phenomena = is that this uncoordinated flight situation must create some kind of vacuum= on my wing tip around the vent port that sucks the fuel out towards the wi= ng tip away from the fuselage. I have the regular wing tips and not the winglets.

Any input or advice is appreciated.
