I have a small leak on injector line #6 rite where it connects to the injector tube. It looks like the threads are leaking a small amout. But enough that when it sits for a bit it usually doesnt start first time. Like it has to prime itself again, but starts no problem an runs fine after that. Im looking to replace the line soon. Just wondering if anyone has tried some thread sealer tape to quick fix the problem?! Just wondering if its worth the time to do the quick fix or if it even works

Put enough on there maybe. Those threads don't make the seal. The nut applies pressure on the line and cross over tube fore the seal. You might just have a bad o ring on the tube. Worth a look.  Those lines aren't cheap.

I just had to order one from cummins for my #5. The end in the nut blew off. I was missing the hold down at the rear holding #5 and 6. Figured that put some undue stress on it. $93 for the line and $28 for the hold down parts.

Ok sealant tape seems to be holding up so far. Taped it up an have been out driving around for about 45 mins or so. Everything looks dry still. An actually seems to b running a touch smoother. I dunno if its just me or not lol 

Will see how it starts in the morning. If takes a second try to start then its still leaking or the “fix” was pointless.

I looked one up with the dodge part # and they were around $170.

It was one of the after market vendors , Maybe a after market set of injector lines

Yes. I looked at several Mopar oversstock places and 170 was cheapest I saw. I did order a #6 line from an eBay vendor for $60 to compare what difference there might be, visually any way. Wish I could have found somewhere that carries the isolator blocks. Those are pricey everywhere I looked.
