Hello All,
New here. First post.
I was getting ready to replace the fuel injectors on my 2002 Dodge Dakota 4.7. As I was dismantling the air cleaner and such, I noticed the crossover tube (aluminum tube not a hose) going between the fuel rails was loose.
I can wiggle it about 1/4". Seeing as it is a factory crimp set up, there is now way to tighten it. Is this normal? The rails are still bolted down and don't move. I stopped the process until I know if I need to look into a new fuel rail which seem to be discontinued.
Thanks for the help.

Well, it doesn't appear to leak..... probably just crimped in place, but, o-rings do the actual sealing. Do what you need to, but, once its all back together, cycle the key several times to build pressure in the rail, and verify that it does NOT leak.

 

Thanks Hey You.
I hadn't started the truck in a week so I hadn't seen signs of leaking or past signs of leaking. I wasn't really thinking of looking there as I know I have injector issues.
For the past few months, I've had the smell of fuel for a few minutes when I start it up. I started the truck and wiggled the tube and it showed no signs of leaking but did smell the fuel again. It's hard to believe that it can move that much and not leak. With that, I will continue on leaving the fuel rails alone for the time being. Once again, Thanks

Hey friend, if you aren’t seeing any leaks but still getting that smell it might just be because the seal on the tube is liquid/pressure tight but some of the vapors are still getting out. I had this same exact problem on my 02’ 4.7 all it took were a pair of zip ties and some hydraulic crimpers. If you really want to fix it up good id go out to a scrap yard see what you can’t find there. Shame that most these dakotas already been scrapped out good luck mate.
