Gerotor electric fuel pump, any good?

I used a Mallory gerotor style pump on a build in the late 80's. That car was my daily driver and I never had a problem with that pump for 50K miles. I sold the car with the pump in it and it was still running just fine.

I see no downside to using this type of pump.

It wasn't silent by any means but it was way, way quieter than any Holley vane style pump that I ever used.

Hope this helps. :)
