The gas cap gasket is also available new for about 5 bones part # 17631-VM6-300.
Gas cap before
Removed the gaskets. They are cracked and need to be replaced
I used a wire brush and then wiped them off with wax and grease remover. I don't media blast them.
Mask them for painting
Here is the paint and primer I used
Primer applied. Remember to switch the vent and recoat.
Black paint applied. They turned out good - there is some reflection picked up in this image
I have no experience in rebuilding/restoring the OEM petcock. They are riveted and are not designed to be taken apart easily. The reason I have not invested much time and effort into the OEM petcock is that replacement petcocks that look very similar to the OEM petcock and are readily available (ebay and Amazon) and are very affordable.
