Nice work, sounds like good progress.

But as ngoma suggested, the thing I would want to check now before pulling the pump off is whether the engine will run. It is very unlikely that the drip you're seeing is the reason your already-running engine stalled. It takes a really massive fuel leak to affect the engine's operation at all. They normally run fine even when there is a relatively large fuel leak. I wouldn't expect the small leak you described to have anything to do with whatever caused your engine to quit after starting up normally, running fine for a time and moving the car some distance.

If you got the hard lines primed and the GPs are functioning, then it should be ready to start right up and stay running, even with the fuel drip. So, can it start now?? If not, then we should continue looking for another cause.
