Cat 745c fuel tank beacons don't work PTS 6.3. There is not even such option on the truck, though the beacons are there.
@Tigron I noticed this, beacons also don’t work on the service trailers.
@DieselDrinker45 On service trailers they work when the trailer is connected to your truck.
@Tigron oh ok this isn’t the case on console
@DieselDrinker45 This is PTS bug report only. On live 5.1 this is not working yet. Also, I do not think PTS is available on consoles. You are in the wrong section.
