Also, if you ever fly a plane that has the vent tubes sticking out of the cap, never face the vent aft, it has to point forward.
Is it Brake fluid?

If anyone comes across and new fuel cap and you don't need the chain, please mail me the chain.

It is really there to drag dirt into the fuel tank.

It's assumed that you're smarter than the chain.

Airplanes with rubber bladder tanks can get sucked right dry if the cap is left off. The pressure atop the wing is lower than the pressure inside the wing, so the bladder collapses toward the open filler and squeezes all the fuel out. To make things worse, it also lifts the fuel sender's float so that the gauge reads full.

Also it increases your chances of vapor lock. Not a major factor at sea level, but a high mountain takeoff, you might lose fuel flow to you engine.

My bladder tanks have snap retainers. I don't think the bladder will lift much but I know for sure the sender arm will. And the opposite tank wasn't affected in my case. I didn't know it at the time but post flight fuel qty was what had been indicated in that one. I did switch from off to left tank (the capped tank) but still the final three miles over that cold ocean water had my full attention.
