I am about to pull my injectors out and send them off to F1. I was advised to buy the new copper washers and connector tubes. I went to the Cummins store and they looked up the parts with my engine serial number. I have these parts and wanted to make sure they look like the right parts. Also, does anyone know if my injectors will get new o-rings before F1 sends them back to me?

 

injectors from f1 will have new copper washers and orings. Yes, what you have there is a connector tube and the washers

 

Those are the correct parts. What is the purpose of getting new connector tubes?

 

I read a few threads in here about changing out the injectors and Dodge says that anytime the injectors are changed out the tubes, o-rings, and washers should be too. I think just to prevent leaks. I only want to do this once. Just trying to do it right the first time.
I don't take short cuts because they almost always cause the job to be done twice, and that stinks.

 

I would change the tubes as well, I had a couple leakers when we did mine. I ended up replacing them all for piece of mind. The o'rings I don't think are a huge deal if they are in good condition.

 

Change the tubes. I had a leaker even though it looked perfect and I followed the instructions to a T. Cummins shop in town told me to change them every time.

I believe the reason I had the issue is because the injectors I got back were not the ones I sent in for core. (couldn't have the downtime back then).

You may be able to get away with not changing if you keep them together with the original injector it was mated to.

 

so how much were the tubes o rings and washers?

 

The washers were $2.30 each and the tubes were $26.99 each. I called the dealership after I called the Cummins store and the guy said that the price that the Cummins store was giving me was much lower than the price he could give me. I thought that was strange. I did not get new o-rings beacause F1 should have new ones on when they send my injectors back.

 

cool thanks rock

 

Make sure to have your engine serial number when you call the Cummins store. That is the first thing they will ask for.
