The "On The Map" quest in Arc Raiders sends you across the entire Spaceport map to triangulate four positions before marking a hidden container. The very first objective — "Head to where the Fuel Lines snapped, and transmit your location" — can be confusing because the game doesn't place a waypoint for you. If you're stuck on this step, the answer is straightforward.
Quick answer: Go to the Fuel Lines point of interest in the southern part of Spaceport, directly south of the Departure Building. Stand in the very middle of the long pipes — right beneath where the words "Fuel Lines" appear on your in-game map — and interact with the triangulation prompt.
Fuel Lines location on the Spaceport map
Fuel Lines is a labeled landmark on the Spaceport map, not a hidden spot you need to stumble upon. Open your map and look south of the Departure Building. You'll see the name "Fuel Lines" printed over a stretch of large industrial pipes. Head to the center of those pipes, and you'll find an interact prompt that reads "Triangulate your position." Activating it completes the first step and updates your objective.
After transmitting, your quest handler will tell you the reading was off and redirect you northeast toward Fuel Control for the second triangulation point.
Full "On The Map" quest steps at a glance
The Fuel Lines step is just the beginning. The entire quest chains through five locations, all within Spaceport. You don't need to finish every step in a single raid — progress saves between runs, so getting knocked won't reset you.
| Step | Objective | Location |
|---|---|---|
| 1 | Transmit from snapped Fuel Lines | Fuel Lines POI, southern Spaceport, south of Departure Building |
| 2 | Transmit from antenna near Fuel Control | Fuel Control POI, northern Spaceport, near Rocket Assembly — look for the large satellite tower outside the western door |
| 3 | Transmit from cactus patch in wall breach | Large wall breach between Rocket Assembly and Container Storage (the southern breach, not the small one near Rocket Assembly) |
| 4 | Transmit from roof of Container Storage | Take a zipline on the eastern side of Container Storage's ground floor up to the roof |
| 5 | Find the tarp-covered container and mark it | Ground level of Container Storage — a white crate propped at an angle in the wreckage; spray Leaper graffiti on it |
Tips for getting through the quest safely
Because you'll be running through wide-open terrain for most of these objectives, consider loading into Spaceport with a free loadout. You won't need to extract to complete the quest, so there's no reason to risk valuable gear. The stretch between Fuel Lines and Fuel Control covers roughly 500 meters of exposed ground, and the wall breach area near step three often has a Bastion patrolling nearby, so stay alert.
How to confirm the quest is complete
After spraying the Leaper graffiti on the tarp-covered container at Container Storage, the quest will mark as finished. You can then extract from Spaceport — the east elevator is a convenient exit — and turn the quest in back at Speranza.
