Must be some kind of east coast expression.    ;)    Or I got the
apostrophe wrong?

Happy to help.

I'm totally fascinated by the fact that fuel is running past the coil
and armature etc. But IIRC, and as has been mentioned here before,
there's no oxygen involved so....

The pump chamber plate is magnetic. Huh. To attract unwanted metal
bits much like an oil pan drain plug? Or is fuel moving too fast or
that?
