Fuel Pump Fittings Question

99 WJ Limited, 4.7L
A bit ago I replaced my fuel tank skid without fully removing the fuel tank. Afterwards, I could smell faint gas smell
After driving and mileage dropped significantly. I checked fuel filter fittings and they seemed fine. Today I dropped the tank and checked out the fuel pump hoses and fittings. There was a bunch of dirt around the fuel pump that was soaked with gas. There is also a bit of fuel under the tank as well. It seems like one of the fittings is loose and allowing fuel to spray/leak under drive pressure. Feeling the fittings, it feels like the one on the very right (pic is oriented with tank dropped and me at the rear of the jeep facing forward) is loose where the fitting enters the pump cover and, as you can see, the fittings are corroded as well.

Is this a replace the whole fuel pump and housing situation, or can I replace pieces to try and stop the leaking? Any other ideas about what/where it might be leaking to cause this problem? It showed up after the skid replacement, no fuel smell/problems before that. I am going to let it dry out and try to button it up tomorrow, so I greatly appreciate any input/direction.

My leak was at the connection going into the fuel pump top. The connectors were totally corroded and after various attempts to get them apart, over a span of several days, I ended up putting in a new fuel pump and getting a new fuel line set (pump to fuel filter) from the dealer. Expensive, but it fixed the problem.

My issue was a loose lock-ring with a bad pump. The gauge stopped working too. So I had no choice but to replace the pump (with a full tank of gas). It started leaking from the ring after a fill-up, no problem, just don't top it off. But then it was so hard to start and the gauge didn't work, so new pump. The lock ring needs a special tool to remove and tighten, in my case just to tighten since it was already loose before I dropped the tank. I broke two studs on the right side trying to remove the skid plate so as a result I can't put my hitch back on. I have it the skid plate on that side held in place by one full bolt and a lug nut on the half bolt that broke, dam. Wait, it gets better. So now I have to drop the tank again to tighten the lock ring again, this time with the tool I just bought of Amazon. Do you believe Autozone, pepboys, advance, and NAPA do not have a spanner wrench to properly install the pumps they all sell? any way, does anyone have recommendations on how to remove broken skid plate studs? Thanks!
