No, only the posts that don't have anything to do directly with the OP's question. NO Dodge Ram has a pressure regulator on the fuel rail OEM. If anyone wants to start a thread regarding doing a fuel system swap , so you can have a return line , than have it , no prob. Thanks

 

Will a harness from a 5.2 work on my 5.9? I have found a couple 5.2 harnesses but no 5.9's

 

Yep. Harness is exactly the same.

 

OK what about the year models? Ideally I want one that will just be a direct swap out. When did the injector connectors switch to the more oval design?

Mine look like this one

 

As some of you know my truck recently had an engine fire. Some of the injector connectors had the heat shielding melded off of them during the fire. I am replacing the entire harness but I am also worried about the injectors themselves. None of the connectors were damaged just the wire wrapping got hot. Do you guys think the injectors themselves are ok? Is there a way to test them if I pull them from the truck? My truck still isn't running so I cant start it or anything like that.

 

Not really without sending them out or starting another fire LOL . I think they should be fine if they didn't get melted. And I'm going to move this thread into your other one. No reason to start another that has to do with the same issue.

 

Ohm out your injectors. If any of them melted internally, that will tell you. Should be around 12-16 ohms. Any less, and they are toast.

 

What about the year models that will work with my injectors?

The engine harness is the harness that has the ac low pressure switch that is in the accumulator on it right?
