I *believe*, but don't know for sure, that they are a safety device in the event of a fuel line being damaged in an accident. I can see how it would vent back to the inside of the tank if the line to the rail was crimped shut, can't get my head round how it would help if it was ruptured. Wrong place for a pulsation damper, they are usually near the fuel rail / injectors. It's a stock thing, anyway. If you weren't worried by whatever safety advantages it may offer I see no reason not to be rid of it. My Skyline has never had it in place.
