>>>Robert--I assume the problem is that your new engine is fitted with a
'race' intake manifold that has no provisions for vacuum take-off? That's
the problem with such things.
One solution is to have a bung welded to one of the intake runners. When
I faced the same problem with my GT350, I took a different path. I fitted
a Boss 302 carb spacer, which has provisions for brake vacuum, yet is very
thin to provide hood clearance.
I got mine here:

You could always just get a typical one-inch spacer, but that adds height
that you don't want. This spacer is very, very thin; the round pipe goes
oval as it enters the side of the spacer, reducing height, yet the total area
remains unchanged.

(Those are photos of a used original, not the new repro, which is built to
the same standard but obviously looks new).
Note that it is somewhat fragile; if you manhandle the hose onto and off of
the pipe, you'll break it. Install the hose onto the pipe holding the
pipe in your hand, then lay the spacer in position, and manhandle the other end
of the hose onto the pipe under the car.
Easy peasy!
In answer to your actual question, I have seen a number of Pantera owners
attempt to incorporate electric vacuum pumps, and every one of them was just
miserable. Those are another 'race only' part, and are deafeningly loud
and create a ton of vibration. I find them completely intolorable for a
street car, plus they take up a lot of precious front trunk space. And they
are more expensive than the simple spacer shown above.

It would be great if possible to find a source in Germany (or
Europe) as the
car is in Germany.
