Fix the Necropolis water pump

Fix the Necropolis water pump is a side quest in Fallout.

Detailed walkthrough
After talking to the underground ghouls of Necropolis, travel to the watershed area and then enter the Necropolis sewers that are being guarded by Larry. In the eastern end of this section of the sewers lies a pile of junk. It is essential to the completion of the quest.

The Vault Dweller then needs to approach the water pump and use their Repair skill to fix the pump. A successful skill check will fix the pump (a tool will help greatly). A critical failure will remove the junk from the Vault Dweller's inventory and deal 1 point of damage to them.

Then the Vault Dweller can rest easy that they have saved the ghouls from death. For a while, anyway.

Rewards

 * 1000-2500 XP for repairing the pump.
