A few of my injectors look like they're leaking. How hard is it to change them (for someone who hasn't done them before)?

Where can I get an O-Ring kit?

 

Where do your injectors look like they are leaking at? The only places I would think they could be leaking would be where the top line screws onto the injector ( no o-ring there) or the return line (copper banjo bolt). If you are seeing leakage anywhere else, there are other problems.

Give us a little more info to figure this one out.


As for how hard it is, it is not. I had never changed them before and ti took me about 1 1/2 hours from start to running truck. I made a slide type puller (necessary) and had a 3/4" pipe brush to clean everything out.

As for where to get the necessary hardware, that's easy ...Cummins.

Why the slide puller? I only ever did it once myself and the just pullrd right out. Lucky I guess. But even if you needed the puller, I would agree it is relatively simple. I also agree with potential leak areas(top nut or banjo fitting)

 

That's the situation we all hope for, but that's the exception rather than the rule. Injectors can be downright obstinate.

 

Just pulled mine out tonight after about 6 months in. Every one took several good pulls with the puller. I think I would be concerned if they just pulled out by hand.

I'll check the top connections. I'll report back soon. Thanks!
