Oil Pump Vane Profile Question 25 DB

[oldodgeboys]

My 25 DB oil pump vanes have tip profiles of being almost fully rounded. There is some wear, so I can’t really tell what the original/correct profile should look like.

I know these pumps are not 'high-output' pumps. They're probably more mediocre-output than anything else. Still though, my pump pressure build-up is sure slow.

Given that there are several factors that contribute to oil pressure and rate of pressure rise; does anyone know if the oil pump vane tip profile significantly affects the oil pressure?

Does anyone know what the original/correct profile looks like? Should they be rounded, or more flat on the pressure side, or ??

Thanks to all.

the vanes for your pump should be rounded with 1/8 radius
