Rudder trim question

Amazing what only putting the vent on the left does

See my previous post. If the caps are sealing and their vents aren't leaking, the tanks will feed evenly enough unless the pilots has a wing low. The underwing vent feeds into the LH tank, and that tank is plumbed across to the RH tank via a high tube across the front of the cabin. If there is no air movement, the tank pressures are equal. When the tanks are right full there will be some fuel transferred through that vent tube from left to right as fuel is burned. This will stop once they drop to 3/4 or so.

There's about three more things that can cause it. John Frank at CPA can discuss it at length if you're bored. It's not always the caps.

They are a fine place to start, however. You won't find the seals' part numbers listed in Cessna manuals. You can get those from CPA also. No need to replace the whole cap as many people do.
