fuel flow from left and right tank

I have owned my 182Q since new and initially invested a lot of time trying to solve the fuel imbalance. The 0.03” tolerance in the adjustment of an external vent is a joke. It will move in a short time. I finally learnt that some fuel tanks imbalance is part of the SE Cessna personality and it doesn’t represent a risk. It’s impossible to dry a tank when flying with the fuel selector in the both position. The vented fuel caps, btw, are “secondary” vents to prevent an excessive low pressure inside a tank, but they do nothing to balance the fuel. Enjoy the sky.

Thanks for the drawings. I will check it out or have my mechanic check it out now while it is having it annual done.

thanks for the drawings . I will check my vent tube out as soon as it gets back from it's annual.

Here is the one from my Cessna 100 Series service manual that includes the 175. Not much difference than what Steve posted.

Thanks for the information. The right tank already has a vented fuel cap. I am not sure of the exact positioning of the vent line behind the left wing strut. Do you know what it is for a 1962 cessna 175C.
