Faulty 1750 oil pump

[Edward Solstad <esolstad@domain.elided>]

We just had an aftermarket 1750 oil pump seize on a rebuilt engine. The
engine had been started with all vital signs showing OK. Upon a subsequent
start up, the pump seized. When the replacement pump arrived, it was
determined to not spin freely - obvously from the same source and not
suitable for installation.

Has anyone had recent experience with 1750 oil pumps and can you recommend
a reliable supplier? 

Thanks much,
Ed Solstad
