I have a friend that has a 1997 5.9 Dodge Diesel tow truck. He says that his engine has a "screen pump" and a fuel pump. He has replaced the original fuel pump with an in-line electric pump. He has also installed an in-line filter. His engine when idling will start to die as if starving for fuel but you can bump accelerator and it catches back up. He is wanting to add a fuel pressure gauge but doesn't know where it should be added. Would appreciate any assistance. He doesn't have access to a computer and is missing out on being able to ask these questions from this type forum.

 

If you do a search, you will probably find pictures but here is a verbal description.

Take the banjo bolt at the inlet to the injection pump(rear outside top of pump) and drill and tap it for the fuel pressure gauge. I would recommend drilling down through the bolt as that will help you make sure to be centered. You can buy an entire kit from several sources, I would recommend dieselmanor which you can find online.

 

Here you go Checking 12 Valve Fuel Pressure

 

Thanks to you both, Darthmouth 12V and Infidel for the information. I'll call my friend over tonight and give him the print-out.
