no, you should care less because the 2010 camaro 1SS is out with 416hp,
drive that 2002 to the wrecking yard
only way fuel vapors are going to leak is if you install the adapter and fuel pressure sending unit so poorly that you don't tighten it down enough, and if you don't use a thread sealant or teflon tape like was mentioned.
teflon tape will work just fine if you use it correctly, the main reason it isn't recommended is because you can get tape fragments into the fitting upon uninstalling and reinstalling the fitting. And the other thing with teflon tape is if you use too much you can crack your fitting if it's a weak material such as plastic.
the following thread sealants are rated for gasoline, and basically anything else on the planet except oxygen, you can get them at home depot or lowes or any plumbing store:
hercules Megaloc (which i use on everything, probably won't find at depot/lowes though)
hercules real-tuff (recommended)
rectorseal #7, or #5
or you can pick up permatex ptfe thread sealant at the auto store but you'll pay more and get less of the same stuff mentioned above. Don't use an rtv type sealant. http://www.herchem.com/products/thread_sealants.html
