Otto, your pictures show the fuel pump with the glass bowl pointing up. I thought they were supposed to be point down to collect any debris coming through the line? My fuel pump only work with the bowl down.
Contrary to popular belief, the glass bowl is not a sediment bowl. It is simply a cover for the filter on the pump. GM never referred to it as a sediment bowl but calls it a cover in literature.
It mounts on the truck with the glass cover on top. If you have a 216 with the same kind of fuel pump I have, it will only mount as you see in my photo.
The same is true fro the glass bowl AC filters found on many GM cars in the '50s and '60s. They are not sediment bowls regardless of how they are oriented on the engine.
Some GM brands mount them with the glass bowl on the bottom leading many to believe it acts as a sediment bowl. Cadillac mounted the filter with the glass bowl on top.
The turbulence created by the fuel pumps inside both types of filter bowls makes it impossible to collect sediment. That's what the filter element is for.
