I'm organizing some stuff and came across both boxes for the fuel pumps. The one I linked is the one I originally bought and is currently installed.
The one that failed was P4594. I wouldn't write that one off as a bad part because of one unique failure. If that is the only one available in your area, for some reason, it will be ok. The big difference is that with P4070 (the link) which is rated at 4psi, you shouldn't need a regulator for a modern carb but for P4594, 5-9psi, you might.
