Codes are 0559 & 6864, both inactive at the moment but my trailer broke down this morning so I haven’t done any good pulls. I’m going to have Insite connected tomorrow morning on the 1st big pull and hopefully catch it in an active state

you need to take code 559 VERY SERIOUSLY!!!>. Here is why...

That’s a brand new fuel pump. It’s only got but 2000 hrs on it

Ok I did a leak down test and failed. Opened the hood and what do I find? Fuel everywhere! The pump, the pressure line, the relief valve, the rail, the fuel filter, the return manifold the frame, the steering reservoir. Gonna be a tough leak to pinpoint FML

Update
All my fuel supply tube nuts were loose by 90 degrees, everything is retorqued and good news. No leaks, passed leak down test. Ran a trip today and no 559 code, no imap codes. Finally feels a little light on power but I’ll take it as a win.
