NOS Fuel Pump

Is there any risk in installing and running a 25-30 year old NOS fuel pump? I'm thinking about the internal parts such as the diaphragm hardening and cracking. Anything else to consider? Thanks, Joe.

Leaks would be my only concern. What engine?

[stovebolt]

230 L6, but I imagine any problems would be common to all engines.

Not necessarily so but on a L6 I would watch for the diaphragm rupture and pumping gas into the oil pan.
