How to Change Fuel Filter ('88 5KSQ)

["Christopher Ritchie" <critchie11@hotmail.com>]

The Bentley does not provide any instructions on how to change the fuel 
filter on my 1988 5000S Quattro.  Do I just unbolt it, and catch the 
spraying gasoline as best I can?  Or, is there a recommended procedure 
whereby the engine is run with the fuel pump disabled (pull the fuse), 
thereby depressurizing the system and emptying the filter?  If the 
latter, will the system self bleed?  Or, do I need to go through some 
other procedure to bleed the system?  What do most people do?  TIA
