70quad:
Thanks guys, now I see how it works. Also, my bad, I meant to say a GF427 filter, NOT a GF432. - Dale.

Cliff Ruggles:
Thru 1967 q-jets used the early style filter.  It requires a thin gasket to effectively seal against the filter housing.

Many early units used a filter housing with only 3-4 threads and they were NOTORIOUS for stripping out the carburetor threads.  Some are threaded deep enough to take a later filter housing.

The "post" that is cast into the carburetor aligns the filter in the center of the filter housing.  We have to break it off when installing heli-coils for stripped threads, they usually break very easily due to the age of the material.

Once the "post" is removed you can upgrade to the later short paper filter.

We sell both styles, and they come with a new spring and the gasket to seal them at the filter housing.

We also sell several different filter housings with 7/8-20 threads that offer more threads to get into the good material if the first few threads are stripped out.  They can be good repair in lieu of having a heli-coil installed for some castings, but it must be threaded deep enough to take additional threads. 

For some castings the only viable repair is going to be having a heli-coil installed.  We provide this service for $45 plus return shipping, turn around is 1-2 days.......Cliff
