thats what its for, however i've binned the quick disconnect as some have complained of the o-rings getting nicked and leaking. i figured one less thing to go wrong so removed it from my fuel line and replaced it with golan mini in addition to the filter in the tank and fuel sock. the little tiny filters seem very easy to get blocked up and hoping the larger surface area of the filter sock and golan will keep it clean and run enough fuel without blocking up once it traps a few particles.
