    Hi,

    ......"Even though it has the pickup in the back of the right tank I wonder how the fuel pressure is when it’s less then 1/3 since it routes down under the seat and back up again."

    It's also important which wing you raise, or lower, when slipping it in. Slipping into a wind might not always jive well with running on the fuller tank either. I've had the engine quit while flying level but slipping hard for a camera guy in the back seat.

    Humm, not all Pa-22’s have the gascolator under the seat. Mine is on the port side bottom of the firewall. I still am required to have the “Level flight only on right tank at 1/3 full or less.

    The right tank rear fuel line runs down behond the door, under it, then up to tee into the front line and goes across the dash to the fuel selector.
    That's why there's an issue that arises under 1/3 in odd attitudes. The gascolator under the right seat is there because of the low point created by loooping that rear line under the door.
    The Trimmer STC runs the lines under the seats to the fuel selector, which gets rid of the low tank/odd attitude issue.

    Look inside of the right main landing gear for a sump drain. There should technically be two gascolators. The one on the firewall and the one just inboard of the right main gear leg.

    Thank you. I found it and took a sample from it today. It was clear, but the first sample from the right tank showed a tiny bit of water, and OMG the left tank had to pull a couple samples to not get any water.... But that said, I didn’t get off the ground today because of a cataract of fuel from the carburetor.
