How much fuel?

How much fuel should be coming out of the black rubber hose on the front of the ip? I pulled my while it was running today and was surprised to see that is wasn't spraying out, just a healthy drizzle coming from the ip side of the hose. Is this normal? I have never checked it before and so I am curious to see. It has about 2,000mi on the new injector pump and lifter pump.

That sounds normal to me. It doesn't spray out on any that I have worked on. The combination of the IP return and the 8 injector returns adds up to a pretty heavy return to the tank, but each one by itself doesn't seem like much.

Well this wosent form one injector it was from the black hose one the front of the IP that connects to the hard steel line that becomes a rubber hose and connects to each injector. Also what is this for as it seems to run normally with it disconnected and spewing diesel or connected.

Pinch it off and watch your truck cease to run!

That sounds normal to me = Not very much fuel comes from the Injector pump return.

The combination of the IP return and the 8 injector returns adds up to a pretty heavy return to the tank = The small amount of fuel from the line in question, and the small amount of fuel from each injector = steady flow to tank

The return line allows fuel to return to the tank instead of dumping out on the ground. As Recovery 4X4 noted. The engine will not run with the return line blocked. It has to let the fuel go someplace and back to the tank is the best place.
