Fuel Rail & Banjo Nut

Quick question guys

On top of the fuel rail is what looks like a check valve that returns to the stock fuel filter canister.

Is this a check valve that will only allow one way flow away from the rail or will debris get down threw it to the rail? What is the real name for it?

Thanks

I replaced the top steel/rubber washer with a copper/rubber oil drain plug washer from a parts house. Tried to keep debris from falling in.

Can junk get back trough the PRV to the fuel rail?
