Fill 'er Up is a mission in LEGO City Undercover: The Chase Begins.
Walkthrough[]
Approach the valve and then turn it. Then use the Jetpack to get up higher on the fuel station. Switch to the Police Officer costume, using the grappling hook to pull down the ladder. Then climb up here and use the broken valve pieces to construct a new valve. Turn this valve to get the initial fuel leak under control.
Use the zipline to reach the forklift that has the piece of segmented pipe needed to fix the broken pipeline. Drive the forklift to the broken section of pipe to repair it. Then get back inside the forklift because the criminals destroyed another section of the pipe further down the line as well. Drive the forklift to the designated area.
Enemies will spawn as a result of doing this. Defeat the enemies and then do the Simon Says-style mini-game on the Astronaut box to open it up. This will cause another piece of pipe to teleport onto its location. Get inside of the forklift. Pick up this new piece of pipe and then drive it to the next broken segment of pipe to fix that up as well.[1]
