Unknown SU Fuel Pump

[Mark Endicott <endicott@bellsouth.net>]

In my big (and growing) box of spares I have found a SU fuel pump of
totally unknown condition.  Is there a way to test it to determine if
it works or is worth rebuilding?  I would assume that if the motor
runs that would be step one and step two to look at the points and
replace if pitted.  Can I pump fuel (or something safer) and put a
pressure gauge on the output and measure it's output pressure and
measure it's volume in a catch can?

TIA
