The truck I'm needing help with is listed in my Sig.
I don't know squat about what is needed so I'm coming to yall. It is all stock and not sure what has been done to it other than Transmission has been rebuilt.
I want to get a list of things that you would add or change to make it a trusted truck.
As far as exhaust would you go like 4 in straights?

Please help me out I'm going crazy trying to figure it out. And please put stuff in order as you would do it.

 

fuel pressure and ATF gauge and drive it.

 

Really depends on what you want to do with it. Fuel pressure gauge, and a big fuel line/fuel pump relocation kit is a great start. I wouldn't go 4 inch straight, but people do. I have a 4 inch with a straight thru muffler. Sounds good, and doesn't drone when pulling.

 

I second those comments...FP gauge, upgraded Lift Pump, to feed the vp, maybe run an additive like Power Service or Redline, Howe's etc to help lubricity of ULSD.

The factory exhaust is garbage if you add HP. Check the 2" crink in it at the rear axle up and over. Cummins sug't a 4". Dodge put a 4" flare on the tailpipe of a marginally 3" exhaust system. You won't feel any difference, just add life to your turbo by freeing up flow....

 

I just realized that none of suggested he change the oil and check the rest of the vital fluids - Hydroboost, tranny, front and rear diff and brake fluid. When I buy a vehicle (I never buy new) I always assume those fluids have been ignored and are in need of replacement.

 

I agree you won't feel any difference (no noticeable power increase), but I've always noticed a significant drop in EGT whenever I've made exhaust system improvements, especially when loaded/towing. It can be as simple a replacing the stock muffler with a straight-through design muffler.

And Tallguy67 has a great point about the fluids. I'd extend that to include a complete vehicle inspection though.

 

Tallguy makes a good point. This will also familiarize you with everything under the truck. Be sure and visually inspect the u-joints and also the transfer case seals for leaks. Solids are stronger, but the zerked ones may last longer.

 

I find it a best practice to change all of the fluids out in order to create a benchmark or reference point to start from. Many people fail to replace the power steering and brake fluids which become contaminated with condensation,wear metals and rubber particles.
