Looking at the fuel lines, it would seem that there are two fuel pumps on my 1972 140hp inline 6. Does that seem right?

Ok, now I have to check 2 pumps to see if they need rebuilding/replacement. I checked one and it wasn't pumping any gas out of it. Do rebuild kits usually fix these? What should I look for when I take it apart?

Thanks for your help Laddies on several different topics.

Aftermarket kits fix most but if the check valves are bad you will need a Mercury kit with the valves included

So before I rebuilt the fuel pumps, the bulb on the fuel line wouldn't get very firm, but now it feels like there is some good pressure there. I'm guessing that's a good sign?
