Fuel Pump Swap

I only just saw this post and I should mention something.

The OP asked "Are the slant 6 mechanical fuel pumps interchangeable with a Hemi fuel pump?"

But you've got to remember who you are asking, Hemi Performance is an Australian Website and yes Hemi SIX and Slant Six fuel pumps are interchangable.

At no point did the guy say big block Hemi fuel pumps would work.

And this is a question I'd like to know myself.
