Bingo! If you have a secondary filter setup after the stock filter, every time you spin it off and install a new one and tighten it down you are introducing crap right straight to the pump and injectors.
LOL, and I suppose changing the OE filter doesn't do the same thing, because well, its magically impervious to any contamination because it has been blessed by the factory.

Oh, and gravity gets suspended, possibly even reversed, when changing these spin on filters as all the dirt and crud just falls right UP into the bases, straight into the system, and instantly destroys the fuel system.

The laws of physics are once again suspended in an attempt to portray a series of improbable events leading to a predetermined outcome that defies all logic.
I needed a good laugh today. :-laf:-laf
