Fuel pump trouble

The missus and I were out enjoying the sunny, summer like conditions last night, so we went out for a nice dinner, and made a last visit to the ice cream stand before it closed for the season. The car was running fine, since I got the carb cleaned up and back in tune, but tooling along a few miles from home it started surging and losing power. I pulled off on the side of the road, and the engine was still running, so I didn't quite know what to make of it. It reminded me of when the last fuel pump was getting air in it and dying out, and I had put the original fuel pump back in. Only thing I did recently was replace the worn out cork gasket on the fuel pump's cover.

After making sure the engine was still running, I continued on my merry way only to have it stall out another 1/4 mile down the road, but suddenly it surged back to life as I was looking for a place to pull off. I pulled off in a parking lot to make sure it was someplace safe rather than risk stalling on the side of the hilly road. Only thing I could see was that I had not put my homemade heat shield back under the carburetor (oops), but it looked like there was some fuel weeping out around the cover on the fuel pump. That's strange, because that's on the suction side of the pump, yes?

Anyway, I'm kind of puzzled what to look at. Obviously having fuel oozing out from the cover of the pump is a bad thing, since it's directly over the starter motor. Likewise, my wife is losing faith in riding in the car. We ended up calling my father in law to help tow it back home. The other puzzling thing is that just last weekend I had been along the same stretch of road without incident, and it was much hotter out, so I don't think it's vapor locking.

Any ideas?
 
I would suggest that the fuel pump is now working as designed.
 
Do you have a fuel filter installed? If so, that's where I'd start looking. The symptoms you describe fit a clogged filter to a T.

If fuel can weep out from the suction side, air can be drawn in when it is pumping. Same problem.
