Yes.You can get NAPA 4003 WIX 24003 fuel filter

Most people may think that an oil filter’s only potential is to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. However, solvent trap and oil filters can be used as an alternate gun suppressor. The good news is that it is cheaper than the actual suppressor and people can do it by themselves at home. It’s possible to spend $20-$55 around for an oil filter suppressor compared to a standard suppressor for about $600. Also, you will need to pay the extra $200 tax stamp if you want to be legal.

Is it illegal to own the un-assembled components of an oil filter suppressor without registering it?

No, this is an oil filter and a metal adapter. This is a "Solvent Trap Adapter" post published on ebay and wish , "Solvent trap Adapters are designed to collect cleaning fluid in the oil filter without causing any confusion! And only use For this purpose". If you use this feature, you may make some [maybe many] homemade suppressors.
