What are these fuel delivey parts? Please!

What is the green thing connected to the fuel filter in right rear wheel well? It looks like a fuel pump with but no with no wires connected to it.

What is the white plastic thing on a separate fuel line (I think it is a separate fuel line) mounted behind the metal fuel filter?

I will attempt to include pictures..

Thanks, EWM

Not sure I ever remember seeing any parts such as the ones you describe on any of my 928s. What year & model is your car?

1979 928

White plastic thing that looks like a small low pressure fuel filter seems, after inspection, to possibly be a valve to stop gas flow id the cat turns upside down. It's definitely not a filter. The picture is rotated by 90 degrees for some reason.

Everything is reassembled now. I just did not want to put it back together if something needed work while the fuel filter was being replaced.

Thanks,
