Welcome to the site ,
Your Dodge/Cummins has fuel milage and power capabilities far beyond a basic gasser but it isn't gas-n-go like a gasser either...it's a bit involved but not difficult to manage.
Obtain a repair manual at your favorite auto parts store so you can get up quick on your truck. You also need gauges to get info from your truck but more on that later..
Your 24 valver has a Lift Pump that takes fuel from the fuel tank and delivers it to your Injector Pump(VP44). This VP44 is the weak link and because it's so expensive, it deserves extra consideration. For years the guys here have been trying different things to get the VP44 to live and through basic R&D, they've discovered a few things that help most and are running up the miles.
Fuel lubes and cools the VP44 and we watch that with the Lift Pump fuel pressure. We generally like to see 13-15psi idle, 12-13psi cruising hwy speed and no less the 5-7 psi at wide open throttle(WOT).
A fuel pressure test gauge available at your favorite auto parts store, connected by pressure line to the Schrader Valve on your injector pump and installed in the cabwill get you lift pump fuel pressure to watch. Check my picture gallery.
Diesel fuel has very little if any lubricating abilities so fuel treatments like Power Service, Howes, Lucas and Stanadyne add lubrication to the fuel. I use the MFG's recommend on dosages.
There is fuel returned to the fuel tank from the fuel system and because some of it comes from a passage in the cylinder head of the motor, it's hot. This is fine in the winter because diesel fuel can gel in very cold temperatures BUT in the summer, it can get hot enough that it won't cool electrical components in the VP44. Most folks are keeping their fuel tank 1/2 full or better. We're currently looking for an end all fuel cooler that does not restrict flow or pressure.
Many folks have found that they had no lift pump pressure after they install a gauge or change the fuel filter so be ready for that.
Type "lift pump" in the search box for lots of info.

Welcome. You should fit right in, in Texas diesels are common. You bought a good truck, spend some money and get gauges so your truck can tell you how it is feeling. Over the long haul, it is the best money you can spend on your truck. Spend some time reading in the 2nd gen forum, and you will learn alot about your new toy. Stay awhile and get comfy, there is a lot to learn.
