Obtain more equipment is an unmarked quest in Fallout.

Detailed walkthrough
Go talk to Overseer Jacoren, on Level 3 of Vault 13. Keep on telling him that your quest for the water chip is going badly, until you get the option to tell him that your mission would be easier if you had more equipment. The Overseer will then give you some extra equipment.
