318 - 4 running like a dog, until...

I have a 318 71 Duster, when I was driving down the highway at speed and accelerated the car seemed to hesitate. Once it got to speed it cruised along just fine.
When home I check the pressure on the 3rd electric fuel pump I have had in the last 1500 miles.
I was barley getting 2psi. I was finally fed up with the electric pumps so I got an $18 mechanical pump at O'Reily's (they said it was OEM).
After fixing the stripped threads in the engine block I installed the pump. I just checked the pressure a couple hours ago and it is now 5psi at idle. When I pulled the hose, it sprayed gas all over, so I pushed the car out of the garage to finish.

Moral: The car feels like it has 40% more power than it did with the electric fuel pumps

Hope this helps someone
