I have an '04 Ram CTD and am 99% sure I have a bad injector. It's only got 94k miles on it but I'm sure the warranty will not cover the repairs due to the dirty (free) fuel I've been running and the fact It's had a programmer on it may show up somehow. If warranty does not cover it, would you replace the bad one(s) with stockers or cough up the cash and get a whole set of aftermarket ones?

With the money you saved not having to pay for fuel, I'd buy a complete set of Flux injectors from F-1, then invest in a supplemental fuel filter setup.

I've looked around on DTR but haven't seen whether or not they sell injectors. Am I just missing it or would you reccomend somewhere else to purchase them online?

Also, do you know of a "How To" thread that gives specific instructions on how to change the injectors? (again, i've searched but came up empty handed.) I'm no diesel specialist but can follow instructions pretty well and would like to decide if it's something I should try myself or pay to have it done.

Thanks,

Kevin

Buy from Formula One Diesel (also known as F-1). The problem with injectors is you need to send them yours to be checked, fixed (if required) then the new nozzles installed. If you can afford the down time it will be worth it.

There is a how-to on here somewhere. Keep looking around. Doesn't look to complicated, just need to carefully follow directions. I'm too chicken to try it, but it really doesn't look that difficult.

What kind of money for stock injectors, F-1 units? With so many converting over to aftermarket injectors, it seems there should be a large number of near-new stock injectors available at a reasonable price. Is this right, or are they required as cores? Also, is there any advantage to updating, (and is it possible) my 04.5 with newer units?

When most people talk about injectors, they are really only talking about the nozzles. The factory bodies are reused. But when you purchase from F-1 Diesel, they go through the bodies with a fine tooth comb and repair any damage. The bodies themselves are very expensive.

Awesome, thanks for the info. So you really don't replace the "injectors" themselves but actually repair the stock ones if needed and change out the nozzles?

<--- Newbie at this. I've been doing lots of reading but it's not quite all clicking into place just yet.

lol.... You answered my question while I was still typing it out.

I'm guessing a stock injector is going to be in the ~$400-$500 range so I would probably be better off just paying them to remove the injectors, send them to F1 for repair/upgrade, and then reinstall them if warranty will not cover what is wrong.

If I did go the F1 route, how much more power do you guys think I would see out of my Superchips programmer?

Not sure on that, but in general injectors are at their best with added pressure from a tuner.
