replacement fuel pump recommendations?

[Pawzi]

Hey all!
its been a while since i have gotten to tinker with my poor 600 sedan.
here's a quick history:
this car sat in dry storage (nevada) for approx 15-20 years before i
bought it in 2003.
the tank was refreshed and the sending unit replaced right before i
bought it by the previous owner.
it ran well once i got it home and cleaned the carbs and shot it w/ some
starter fluid.
it took me some time to get it cleaned up and road worthy (read: mouse
infested from storage).
i drove it for about a year and then let it sit for about a month (rainy
season).
when i went back to start it up to let it run for a bit and take it for
a spin, it started making a racket from the lower front corner of the
driver's side (loud clicking) when I turned on the key and it would
crank over, but wouldn't start.
that's where the fuel pump is located, correct? (kinda below the
headlight behind the fender)
i'm affraid sitting for a month let something settle in the pump that
gummed it up or broke it.
so I am looking for a replacement pump but none of the GED hopefulls at
the local parts stores can even find anything on file for this car
(since it's older than 1985 [/:)] ).
anyways...so i have found a few candidates:
Parts America (Kragen locally here) carries a couple options (i think)
but there's not really good descriptions online.
Carter Universal Elecric Pump - $81.99 (no PSI/gph rating listed)
BECK/RNLEY Universal Pump - $68.99 (Rating on this pump is 1 1/2 to 3
1/2 PSI)
is either of these a suitable replacement for our cars?
Is one a better option than the other?
is there a better recommendation or cheaper option?
Thanks for your input/feedback/help!

There is a small inexpensive one that uses a sliding piston/check valve that is sold at Napa I believe. You can find them for about 25 bucks as I recall.
