See above.

This is the kit that Lasar sells.  It lists the part numbers if you want to buy them separately.  I lubricate them with EZ Turn Lube.

Make sure to replace the little o-ring down inside the cap, too. It goes around the center rod.

Be careful on the little one in the center hole when you remove it. 

Use a brass tool to work it out 

Using a steel screw driver may/will gouge the grove it sets in so it won't seal good

The blue orings are the only way to go but If you do use the black ones replace the big one every year especially if the

airplane sits outside on a tie down. 

Lube the little one in its hole before you assemble the pieces. Adjust the cap lever and then use a new cotter pin on the nut.
