All the parts stores show a paper filter for inside the quadrajet instead of the metal screen (and spring) that I'm replacing. Is this a new item to replace an old item err what?
 
I remember there being two sizes of a paper filter, one long, and one short. The short one wanted the spring. I seem to recall Wix 33044.

I also remember that they both chugged up in no time and were a pain to swap as the aluminum casing they live in would strip its threads if you looked at it funny, and I could never remember which way the filter goes -- they're directional and almost, but don't quite, flow properly when backwards.

I removed them and went with a much larger external inline filter, e.g. Wix 33033.

Metal screen? Not a sintered bronze filter? http://quadrajetparts.com/images/GHP-Q2252-400w.jpg

From what I've seen over the years the paper filters were much more common, but I also tended to stick with late 70's and 80's Q-jets.

I'd replace it with whatever fits that you can get cheaply and easily. Those filters are kind of pointless anyways (IMO) the spring is there so that IF the filter gets plugged up, the fuel pressure pushes the filter off its seat and simply bypasses the filter.
 
Yeah,GM used sintered bronze "slugs" at first in the 60's and went to the short or long paper element fuel filters later on,and some had a rubber spring loaded check valve to supposedly prevent fuel from spilling out of the carb in a rollover..(sure that worked great!..:rolleyes:).....as noted they were easily plugged or stopped the fuel flow when water got in them,and they also could just get pushed back by fuel pressure if they did clog,and allow dirty contaminated fuel to by-pass the filter..and the carbs often stripped the fine threads on the inlet fitting hole when you went to change them,ruining it..:doah:

I always chucked those filters in the trash and installed an in-line universal one in the fuel line elsewhere...it wasn't GM's best design,that's for sure..
