I have a 2017 DF60 that is having starting issues. It has a 2-2 alarm code. I checked it out with the computer but the code doesn't pop up, so I assume the oil change is fine. Spark is fuel, the fuel pump is pumping out fuel, but my problem is at the VST. I unclamp the hose that goes to the fuel rail and its bone dry, I try to start again and nothing is coming out that hose. I can hear the pump, pumping but not coming out. I drain the VST and the fuel coming out is pretty bad. I take VST out and it cleanish. On the picture I attached is the two filters. I took out that were full of garbage. But my question is on the same picture number 12 which is the regulator, can I pull that out? or how to clean? does it go bad? I put compressed air through I nothing goes through. Now that I have it apart I want to see what to do. Thank in advance for the help.
