You have zero clue what, or who, I know. And $30 was a guess, based on the fact that it's been ~15 years since I last bought a mechanical small block fuel pump at a local parts store and that one was a whole $18 then, so that was a wild guess allowing for the fact that prices have gotten stupid since then.
Nothing has gotten cheaper since then.
Definitely easier to change if needed than an electric in tank pump, and cheaper. You can't deny that. For my purpose a stock mechanical pump will more than do the job. The whole build though won't be completely stock. Mostly, internal engine parts will be "fortified" but much of the outward bolt on stuff will be stock or stock replacement parts for "some" Mopar application, though not necessarily all for the same year make or model.
If you're so smart then enlighten us all....
