Does anyone have an assembly sheet for the Carter 9920 fuel pump (or similar) as used on 1951-1954 Packard? I used to have one but can't find it now that I need it. An exploded view would do nicely just to be sure I get all the check values oriented properly.

The pictures in my How To Rebuild a Fuel Pump should be the same Pump.

I saw that before posting and it’s similar but the details are too different to be helpful for this pump with the various valves in different locations. I can’t tell which is which and that’s the bit I need help with. I can just open up another pump, though, to get it sorted out (I have several of them) but I am trying to avoid doing that!

Think Packard used the AJ style pump and if so, this from a Motor's Manual might help as it has a bit on valves. Ignore the extra R type photos on page two.

Thank you, Howard! That's what I was looking for but didn't think to look in my (father's) beat up 1956 Motor's Manual and not even sure where it is! The Packard manuals, of course, are not too helpful for details.
