Little late but now I rember a the cat tech pulling the plug on the injection preashure valve. That why the logged code but now serv. On the display. Nige, now I get why you kept asking if I saw serv on the display. That code was not reoccurring. I pulled the fuel preasure regulator of the back of the head. Screen is clear. I plan on replacing the regulator. Return line seems flow OK. After that I will put clean fuel straight to the bost pump.

Connected direct to tank fitting with clear line. Lots of air in the line.

Air cleared up after I gave it a little mote time. I belive then fuel.issue wasù a combination of a kinked fuel line where it comes around the primary filter and a lose/improper pipe clamp at the tank to filter hose connection. For the first time , i pushed dirt about 30 minutes . Ran fine no issues. Thank You
