New, was on my 360 magnum for startup but ran into issues I thought were eureka red to the pump but turned out to be missing galley plug but pulled this off and put a new one before I realized what was going on. Asking 51$ shipped.

That's a Melling pump (made for Mopar)...

And the cover is on upside-down.... :BangHead:

The machine finished surface goes inside and the bare cast surface goes outside....

Melling pumps also have 72 psi springs in them... :thumbsup:

Click to expand...

Unless they machined both sides...

Look carefully before taking the cover off...

I don't see the scallops around the bolts under the cover like the ones on the top in the pictures of mine... There would be a gap under each bolt if so - I would think...

I would hate for you to take the cover off if you don't need to...
 
If the pump cover was on upside down wouldn't there be score marks from where the rotors rubbed against it?

Before they came out with these new pumps the old ones were flat on the outside also.
I think you would find that there are channels in the other side of that cover to help promote more volume.
