I'm thinking of painting the fuel fill plate green, to match the

If you go to your neighborhood UPS store they can make up engraved
plastic, color coded plates for you. For another $5 you can buy a
Dymo label making tool with a variety of colored tapes which will
stick to the bronze deck plates. We've adopted both on our GB49 and
they've held up well for over 2 years. I'd like to report that we
were prescient enough to anticipate the problem in advance of making
the labels but that is unfortunately not the case.

I've now taken it one step further and made up color coded ID plates
for the fuel tank valve manifold.
