I would if I could. but don't have that tech savvy! I use the 564 cartridges, lever measures about 5/16" x 9/16" x 2-3/8" with the colored inks, black ink lever is about 5/8" wide. I Drilled a 1/4" hole through side of the wide end for key ring. Hope this helps.Norm, Can you post a picture of the HP plastic lever?
Good description of the function . . .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.
Your finger nails are tougher than mine, Warren!
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.
