GM TPI system

[dzorde at aesprodata.com.au]

     For anyone out there
     
     How do you clean the injectors on the GM TPI systems (85 system).  I 
     presume you have to pull them out of the fuel rail ?
     
     If so, do you have to pull the whole top apart to get the fuel rail 
     off the manifold bosses ?
     
     I know the injectors are held in by a sort of 1/3 turn locking clip, 
     when this is undone do you just pull out the injectors (they seem to 
     be in very tightly) ?
     
     Any help appreciated
