The replacement fuel pump I bought from NAPA had no markings and was assembled in Mexico. Not that there is anything wrong with that.
Well you'll always have a backup replacement handy in case something does go wrong! Perhaps you could use the new one's "guts" to rebuild your original?
Sometimes I find myself making more more work... For instance, I have a starter that came with a 2nd 235 I bought for parts - it's in FANTASTIC shape, but instead I spend a week scrubbing off 60 years of mud and oil off my original one for this...
