PRL flex fuel line degraded and strange DTCs

[jb99]

So the long fuel line that goes from the flex fuel to the HPFP degraded to the point it got a small crack in it and started spraying a mist of fuel everywhere. With that I now have several DTCs

C0703- can't find much on this one
P02CF- Does this mean injector 2 is bad?
P02D1- injector 3 is bad?

I have XDI HPFP and 1400cc injectors. Should I assume that deteriorated fuel line killed my injectors and how can I tell if there is damage to the HPFP? I got this installed early 2022 and am hoping I don't have to replace my fuel system a year later. Of course PRL stopped making their upgraded lines but I see JSR has upgraded lines but it seems like the damage has already been done. Hoping anyone here has some ideas before I have to spend another $3000 for a new fuel system plus installation costs.

Did you use the standard rubber those that came with the PRL kit or the upgraded PTFE line? I'm assuming it was the standard rubber hose. If the hose degraded that bad where fuel was leaking through the line ... likely particles were sent down stream. Prob will need the injectors and HPFP looked at. Sorry to hear about this happening to you.

p.s. I have a PRL upgraded PTFE line for sale if you want. DM me.

They were the rubber lines. I am disappointed they stopped making the new lines 1 year after that service announcement. I have a ticket open with PRL support but I don't think it will go anywhere.

Anyone running original PRL flex, replace hoses immediately. My hoses lasted about months running e30.

I did some digging and C0703 is cam timing is over -retarding. Not sure if that would be caused by 2 failed injectors and HPFP.

i can show you the line where I sealed the crack with an wth an ethenol resistant patch kit. it stopped the fuel spray but I can get pics of inside the line once I get a new one installed. Since my fuel system needs completely replaced, looking around for a new complete system. Probably won't be installed until sometime in Sept
