That messes me up every time. Both my vehicles are different and I have to look at the little arrow in the dash to remind myself as I pull up to the pump.
This is a possible solution

I don't know about other places, but here in Texas when the pumps get busy they have a Costco employee directing cars to the shortest available line. Doesn't matter which side your fuel door is on--Costco has those little retractable cables so you can pull the fuel hose to reach the opposite side of the car. Looks goofy, but it's correct for how Costco wants to maximize efficiency
