Fueling a LRJET is easy but there is a process. As mentioned there is only one filler point on each side, on the tip.

If fueling using a single point you have to be cautious of an imbalance because it can cause the aircraft to tip. First side fill to a 125gal imbalance. Proceed to the other side and fill to 250gal and then back to the other side for a top off. During the event you’re likely filling the trunk (1200# in a 35) and being mindful of a bubble. If your aircraft is prone to developing a bubble then you can open the cross flow and try to force it out by sending fuel from the full wing into the the with with the bubble. Leave the cap off the bubble side for best results.

You can also taxi or tug the plane in a few circles and it will clear the bubble.

In flight the tips burn down first. After the tips burn down passed 5-600# remaining you can start bringing fuel forward out of the truck. The purpose of this is to verify the function of the jetpumps which use motive flow to move fuel.

Baffles, flapper valves and a yaw damper are used to combat Dutch roll.
