Old pump we would only run 45-50mph up the mountains have to shift out of 5th. Thanks for all the good info on here

Here what I replaced injectors,all the injector lines, lift pump, all the boost hoses,turbo,head rebuilt, arp head studs, anything that we thought might be an issue was replaced.

Now for the next step. What do you think I should do Reman, Rebuild or New. I was thinking on sending it to Scheid Diesel and having them give me there honest opinion. Sending the IP and injectors to make sure everything is clean and the BAR is set properly.

I've heard nothing but good things about them. Make sure you tell them that this is a working medium duty truck, not a pickup. They can't get as aggressive with the pop pressures and the fuel delivery without compromising pump life.
