I just finished replacing the #4 injector line after the line on my truck failed last night about 20 miles from home. The local Dodge dealer had it in stock and with tax it was $65. I had just replaced the fuel filter and inspected the lines and brackets. Everything was tight and looked fine at the time. Do yourselves a favor and carry a spare #4 line, an impending failure may not be obvious. The parts guy said they hardly ever sell anything other than the #4 line. I'm going to order one from Geno's, much better price than the dealer although I was happy to pay the price and get the truck up and running again.
The failure took place right at the head side of the line where it attaches to the injector at the nut. The parts guy told me the failures he'd heard of take place where mine had. The line went right on and there was no apparent binding and the replacement had the updated clamp which consists of a one piece bracket with a rubber like sleeve wrapped around the line within the bracket itself. The new style injector line and bracket is all a one piece assembly.
The old style two piece clamp with the blue plastic pieces is replaced along with the metal bracket by the new style one piece assembly The existing bolt is reused to secure the new bracket after the injector line bolts have been tightened. The replacement took approx. 15 minutes and the hardest part of the job is removing the old style clamp but I now realize that if you simply unbolt the base of the bracket you don't need to mess with the old style clamp. Old style clamp and bracket is not reused, only the bolt that secures the clamp is reused to secure the base of the new clamp. Very simple job, hope this helps...... Lighting was awful or I would have taken pictures....
A 10mm socket is used on the retaining bolt for the bracket and a 3/4" wrench worked fine on the injector line nuts. BTW, my truck has a little less than 80,000 miles on her and I've been religious about clean oil and all filters.
