Found out the hard way why injector return lines need replacing more often
I was chasing a hard start on a 2005 Cummins ISX last month. Took me three days of messing with the fuel system before I gave up and checked the return lines. Pulled one off and it was so brittle it snapped in my hand. Replaced all six for under 40 bucks and it fired right up. Anyone else skip the cheap stuff and pay for it later?

Why do people think return lines last forever just because they're not under high pressure? I swear that's the whole trick with these older Cummins engines. The rubber gets cooked by heat cycling and vibration, then one day you're chasing a ghost problem and it's just a cracked hose letting air in. I've seen guys spend hundreds on injectors and pumps when the fix was basically pocket change for lines. It's one of those jobs that feels too easy to be the answer, but half the time that's exactly what it is.
