Spent $90 on a "high-end" fuel filter and learned a costly lesson
I bought a fancy Donaldson fuel filter for my 2012 Cummins last month, thinking it would be better than the OEM part. After 3 weeks, it started letting air into the system and cost me a tow to the shop near Tulsa. Turns out the gasket was a different thickness and I should have just stuck with the factory Fleetguard filter. Anyone else had a bad experience with aftermarket filters on a 6.7?

Nah man, that sucks but I've run Donaldson filters on my 6.7 for years with zero issues. You might've just gotten a bad one or the gasket was slightly off. Factory Fleetguard is solid though, can't go wrong there.

The Donaldson gasket on my 6.7 was 0.5mm thinner than the factory one, and I chased a stuttering idle for two weeks before I figured it out. Did you actually measure the gasket thickness against the OEM part before you installed it, or did you just assume it was fine because it was a "high end" brand? Because that little difference can let air in when the engine gets hot and the metal expands just enough. I learned the hard way that even with premium brands, you gotta check every spec yourself with a caliper, not just trust the box. What did the shop say the actual gap was?
