I'm working on putting a 98 12 valve in my dakota and I have a lot of missing fuel lines. I'm running a air dog straight to the pump with dual feed lines. But my question is on the return, I know there is one large return line on the pump and one off the injectors but what the small line off the back off the p pump. I tried looking on line but can't find a good description.

 

There is a large return connected to the pressure regulator going to the fuel tank. The injector return lines go to the top of the fuel filter.
By saying there is a line on the back of the pump do you mean the air boost line on the top, back of the pump known as the AFC?

 

I got the Afc hooked up, but about 6 inches back from the main return port there is a port in the pump. I can't tell if there is supposed to be a fitting to fuel line or what. I might have to get the mirror out and look. Could just be cast in there for other applications.

 

Off topic question:
Will the unibody Dakota handle the torque and weight of the Cummins?

 

It's a full frame truck. It's got dana 60 axles with 3/4 ton leaf springs. I had a 440 in but wanted something cheaper to put in it and more reliable.

 

Got the hood stack made today
