mechanical to electrical fuel pump conversion 1984 4x4 B2 2.8L V6

So I get a small oil leak at the front of the engine. turns out to be the little breather hole on the fuel pump.
PIc No. 1

I think to myself: "no problem, god knows how long this pump has been in my engine, it was bound to go bad eventually" so I proceed to take that sucker out. BTW, it was a PITA removing the pump cause I had to remove the oil pressure whatnot just to reach the darned fuel pump bolts.

so I get a replacement from a well-known autoparts store, and I install the POS right away. after driving a couple of miles, THE NEW PUMP STARTS LEAKING TOO XD
only this time it's leaking from here:
(I didn't take pics of the new pump, so I'll use the same picture as above)
Pic No. 2

I take it out and drive to the autoparts store to have it replaced. I take the replacement home, install it (always making sure to use the supplied gasket and a little RTV for good measure) and what do you know, it starts leaking oil from the same place as picture no. 2!

Am I doing something wrong?

It's really getting to be a pain having to remove the oil pressure sensor - remove the fuel pump - install new fuel pump - reinstall pressure sensor...only to have to remove the oil pressure sensor again - remove the faulty new fuel pump - install second new fuel pump - reinstall pressure sensor again ... and then starting all over again.

should I consider this a divine sign telling me to go all the way and install an electric pump outside the tank? at first glance installation seems pretty straight forward:

a relay here,
run a bit of wire from here to there
some extra hose here
an extra fuel filter there
a pressure regulator down here
an automatic shut off switch up there
and done, I get the pleasant buzzing sound 2-3 seconds before starting the engine and I can forget about mechanical pumps for ever :)

any opinions? anyone done something like this before? Am I over my head?

4x4 1984 2.8L V6 Bronco 2 with carburated engine. it's not the stock gas tank. I replaced it with a tank from an 85 or 89 B2 (can't remember the exact model) and it has a return line, I just plugged it up.
