Sometimes I have to replace my fuel cap opener after I use it to mix epoxy. Good excuse to have another popsicle here in the Florida heat ...

I usually use a stubby combination wrench like this one. The 3/8" wrench is one of my most used tools so it's always handy.



If I'm opening the tanks during preflight check, I might use my Philips head stubby screwdriver that I carry to open my oil access door. This works okay but the wrench is a natural lever and the bend at the end makes it perfect for quickly popping open the fuel cap.

I use my VW fold a key on the keyfob, from my Electric VW e-Golf. It has a flat, fold out blade, kind of like a switch blade.

If you need anything more than your finger to flip up the tab on your fuel cap, then your cap nut is adjusted too tight and you will end up breaking the hinge pin.

Properly adjust and lube the O ring, and no tools needed to pry up the tab. The cone of the cap must be able to slide and drop as the O ring decreases in diameter so it can fit through the neck of the tank.

Good description of the function . . .

The force needed is very low and consistent with the right lube and adjustment. Although a fingernail works for me, the tool is easier and need not be very strong.

I have used Krytox for nearly a year now. My caps still open and close with a light touch and smooth as butter. No need to wiggle for the opening.

Nylon bicycle tire “iron” work for me, already had a couple of sets so I use one for the RV. Here is a link on Amazon. $7 for 12, share with your friends, lol. Because it is nylon it does not scratch the painted cap.

According to the number of posts I think that quite a number of pilots use a tool to open the fuel cap. So do I. I figured that it is quite difficult to adjust the nut in a way that it allows for opening by finger nail and still have the cap. fully secured in the filler neck when the lid is down.
On my plane it is an either or question. If somebody has a good way how to adjust I d'be happy to read from.
