Okay guys I've finally got some money to do injectors and headstuds. While I'm in there I'm also doing the fca because I have a ready bought it and never put it in thinking that was the problem. But here's my problem. My fuel rail doesn't have a relieve valve I want to put a new one in. It has a steel braided fuel line rated for the psi going from the rail to the back of the cp3 pump. I want to get rid of that so I don't blow the nozzles off my new injectors. I'm runNing a raptor lift pump with custom filter set up and it has a draw straw into the tank. The in take pump is still there just nothing going to it. So what do I need to put a return line from the rail to the tank. I am going to order a relief valve. I have no clue how it looks stock so I don't know what I need to replace it. I do monitor my rail pressure but I just want the insurance of having a 300$ valve in there rather than having to dump more money into injectors. Thanks in advance

Give Todd a call at TC Diesel... http://www.tcdiesel.com/Pages/default.aspx
He sells a modded or stock PRV for about $75 (was a couple of years back though) Then I'd go to cummins & get the return line back to the fuel filter housing which is stock.

So your saying the return line coming off the rail just goes to the fuel filter housing? Am I reading that correctly? I thought it went all the way back to the tank? I wonder if I can get a hprv and still use my braided line that's going back into my cp3

Yes, IIRC the actual return line off the head also goes back to the stock filter housing. Not sure about your braided line. IIRC the stock PRV uses a banjo bolt setup with a hard line to go back to the filter. That part should be cheap from cummins

edit: check that, thought it uses a banjo bolt. Contact cummins...
