Sorry. But typical of the aftermarket, that claim of theirs is flat out lie.
Let's look at
the claim and compare to reality:
"
quality reproduction fuel sending unit from OER. Designed to exact factory specifications, each fuel sending unit will replace the original in every detail and is officially licensed as a Mopar Authentic Res toration Product, proof of their superior quality and authenticity. Each unit comes complete with fuel sender, seal, premium-grade filter and brass float.
Applications:
1963-76 A-Body with 5/16" outlet"
To begin with -
"officially licensed as a Mopar Authentic Restoration Product, proof of their superior quality and authenticity."
This marketing BS. It
possibly would pass FTC review of misleading claim on some legal precedent or reg defining "authenticity" as something different than meaning an accurate copy.
Maybe someone from Chrysler would like to show us evidence of the vetting procedures and standards.
The evidence on the consumer side is that there are none.
There are lots of examples of
Mopar Authentic Restoration Product that look nothing like the originals.
Take this transmission mount for example.

and
here is an NOS original if you want to compare new to new. It's just a functional replacement. Perhaps better, perhaps worse than what we can buy at any parts store - who knows?
Now lets look at the next claim:
"each fuel sending unit will replace the original in every detail"
Replace not replicate!
Replace means functional equivalent. So this means they sell an item that doesn't look like the orignal.
Here's a small photo with the original '67 Fuel sending unit from my Barracuda.
Orignal unit is on top. Notice the pickup tube shape, the float arm and the sending unit resistance winding.

here's another original, year not stated.

Compare that to the "authentic restoration product".

Looks pretty much like all the other 'replica' sending units out there. :(
However we can't even give them credit for providing a functional equivalent.
It's almost certainly not going to always provide a correct fuel reading because the resistance winding doesn't match the float/tank relationship and the gage.

In conclusion -
"Designed to exact factory specifications" is obviously not true.
It may be correct for some years and models, but certainly not for the early and mid year A-bodies.
In fact the part number changed over the years, which usually means the specifications changed.
for example:
1967 p/n 2257 444
1973 p/n 3621 615
Whether the misleading advertising rises to the level for federal level action, I don't know. At least some state attorney general's might be willing to pursue a case, or at least send a cease and desist type letter,as a matter of consumer protection.
