Need to replace Sediment Bulb assembly - paint it?

[SDJason]

Title says it all - I need to replace the glass sediment bulb assembly, and it looks like the replacements available from the vendors (I'm looking at Snyder's part #A-9155) come as bare metal.

My current assembly is painted black; should I paint the replacement as well? If so, what paint should I use on it?
I assume that whatever is used should be fuel-resistant, and not just any ol' paint.

Thanks in advance.
