jzack Posted April 16, 2022 Share Posted April 16, 2022 I've got a 1994 CH with the E7350. Back in December I replaced #4,5,6 injector lines. They were leaking at the head. Now 4 months later all three have failed with small hairline cracks behind the nipple at the injector. Mack has been warrantying the lines but I'm really growing tired of replacing them every few months. Yes, I make sure all the line clamps are good and tight. The lines stay dry for weeks, maybe months and then bam, they start dripping on the manifold. My original lines were 0.25" OD, the new OEM ones from Mack are 0.23 OD I noticed. I let Mack know about this.... Do I have any other options here? Quote Link to comment Share on other sites More sharing options...
