injector connector tubes

[CumminsRam]

Im replacing my injectors and am looking for a site to purchase the connector tubes. Any help would be appreciated

Is this the 1st time you have removed the Tubes?

 

[CumminsRam]

yes it is. i was told it would be to my advantage to change them with the injectors

In and out 1 time I think you will be just fine,just check them you can see the deformed end. I think some will chime in on 3 or 4 time in & out and no problems.

Why are you replacing the injectors? More power or something wrong? As long as the fuel system is clean the tubes are fine to be used again. Look for rust on the outside of the tube, and tap the tube inlet side down on a piece of white paper to see if there is debris trapped in the edge filter. Reuse or replace depending on what you find.

The tubes in this photo are rusted from water contamination and can not be used again.

My ignorance here but if you are having problems with one injector do you have to replace them all? I have been "Searching" and have not seen this mentioned. What is the procedure for determining which injector is the problem?

Ok guys. I've decided not to mess with new connection tubes. Mine look like brand new. No deformation, no discoloration. Tapped inlet on a paper towel. Nothing inside. Thanks for the advice

There are two ways I now of to isolate one (or more) problem injectors...



If you have access to one, a Chrysler DRBIII scan tool can electronically turn off one or more injectors with the engine running. If you turn off an injector and there's no change in engine sound or rpm, then that's a good clue it wasn't working before you turned it off.



If you don't have access to a DRBIII, then you can shut off the engine, remove a high pressure injection line from between the fuel rail and its corresponding injector connector tube (in the side of the cylinder head), seal off the exposed outlet on fuel rail using a special cap available below, and then restart the engine listening for a change in sound. As with the DRBIII method, no change in sound means you've disabled an injector which wasn't working.

BTW, the above caps are handy to keep in your truck's toolbox at all times just-in-case a high-pressure injection line were to ever break. It could be used to get back to civilization if you're out in the middle of nowhere.



Good luck,
