Have a 2014 580 quad with approx 2000eng and 1500 driveline hours. Fuel filters changed 60hrs ago. We were seeding down a very steep hill yesterday and when we got to the bottom we got engine fault code 3141 (fuel supply pressure problem). My initial thinking was something in the tank got sucked into the line going down the hill. Cracked the line just at the fuel/water separator. Seemed like lots of fuel pouring out from gravity as tank is 3/4 full. Blew compressed air through this line in case there was an obstruction. Still got fault within 1 minute. Changed out fuel filters again. Still same code. Checked harness and couldn’t find any wires rubbed through. Dealer thinks it could be injectors and bad fuel pump (as a result of bad injectors). Anybody deal with this code before and if so what was the remedy?
