I have a '99 Ram... will I have to replace my transfer lines? I was told that they changed over in the '98. 5 but I dont want to get stuck in the middle of an install needing to replace things. Is this something I can easily get my hands on?



I was also given advice to buy gaskets for my intake horn and heat grate. Where would I get these on such short notice? I'm doing the install this Saturday. Am I stressing over nothing?



I'd appreciate any input that any of you may have. If you have any other tips in regards to the 24V injector switch I'd be much obliged. Thanks a million.

Johnny, I have a '99 also. I did not have to replace the crossover tubes and also did not disassemble the intake horn or heater grid while doing this. Just take your time and start at the front, by the time you get to the last 2 you'll be very comfortable and won't need to see what you're doing (good thing since you really can't :D) You might want to check out this thread also: https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=20683 I bought my injectors from Diesel Dynamics and they came with excellent instructions.
 
I've changed the injectors on several trucks - only changed the tubes on 1 (a 98) and haven't replaced the gaskets on any of them - no problems (knock on wood, I'm installing a set tomorrow).
 
It's easy.

Johnny,

When I did my injectors I took off the intake horn. I was careful and the gaskets were reused. From what I seen, even if I wasn't careful the gasket wouldn't have ripped. You can reuse it. If it happens to get torn, put a little silicon on it til you can get a new one. No big deal. Your connector tubes will be fine. Just some of the 98. 5's were troublesome. It's really an easy job. I was scared to hurt my baby when I did mine but it was cake work. If you have good instructions it's easy. I had my cousin help me and we did it in just under an hour and a half:cool: that was being very cautious and taking it slow, could do it in under an hour now... I thought it'd take 4 when we started. :) Advanced Diesel Technology, www.smokindiesel.com, has good instructions. That's where I got my 275's. I dunno where you got the injectors, but I'm sure they'd e-mail you a set of instructions. One tip. Get a buddy to help. And when you put the new ones in, make sure to turn them a little bit in each direction and push in on the connector tube at the same time, you'll feel it slide in when you hit the right spot. Like I say, don't worry, it's easy as long as you have a set of instructions.

P. S. If you have problems, call any of the dealers on TDR. Most all of them will help you out if ya get stuck.
 
I would recommend pulling the injector tubes and inspect them. look for any dings on the cone end ( injector end ) and check for any debries in the inlet side. I found a couple little flakes of black stuff in 2 of them. If you do not pull the air horn you will need a better wrench than any of my 3 for the injector line nuts behind the horn.

Happy bombing :)
 
When you put your new injector in... . tighten the hold-down clamp temporarily to "clock" the injector... lining it up with the cross-over tube, then loosen it back up to tighten the high-pressure line. Those cross-over tubes are somewhat fragile, I'd be concerned about rotating the injector while pushing in on the cross-over tube, it would'nt take much to chew the tip up. Just "clock" it first, it has to line up perfect then. A nice little tip from DD. Hope it helps.
 
How do you know if your 98 needed transfer tubes?



Removed the first one last night and placed it against the one's I purchased. Some of the numbers stamped on the tube are different... . but they look identical. Is this something you can't see... but is different?
 
Any special tools required to removed the tubes? I was apparently supposed to do this when I replaced my injectors the first time so... just ordered the tubes and o-rings from Cummins. The part number has changed again by the way (March). Anyhow, just got my BD step 4s so it's a good time to do it. Thanks in advance.
 
Nope, the only thing you will need is a crows foot to get the fuel lines off the back of the injection pump. You will have to completely remove the fuel lines from the engine and pump. They can come off in two bundles of 3 lines, just take the screws out holding the brackets to the intake. It is pretty tight on the back side of the injection pump. After those lines are off when you pop the injector out the connector tubes will be loose and you can use bent needle nose pliers to grab them and pull them out. You will need to bleed the lines at the head to get the truck running again because you will have air in all those lines.

Thanks for all the help. The mission was a success!



Now I need gauges, an EZ box, and Bill K's trans upgrade.



Thanks again for all the help. Especially Diesel Doug at Advanced Diesel Technology for being accessible for my phone calls throughout the install.



Oh, the intake horn gasket broke into several pieces as I lifted it off. So thanks for the advice that I should have taken Statebull626.

If your engine has some miles on it it would be a good idea to get the gasket just in case. It was a pain to locate the gasket and find someone to pick it up.



Anyway, I am very happy with the results.



Thanks again to all that answered my questions.

When i installed my injectors one of my intake gaskets broke.

For a $3. 00 item i whould recomend having them on hand when changing injectors. It's best to be prepared.
