Had a injector stick open on a highway off-ramp in Phoenix last summer
I was hauling a loaded trailer down I-10. Exhaust started rolling white smoke. Pulled off at the 32nd Street exit quick. Turns out a cheap fuel filter let water through. Now I always spec Racor filters on any job. You guys ever seen a stuck injector from bad filtration?

Guess I see it a bit different. Cheap parts can cause issues but a stuck injector usually points to a mechanical failure or debris already in the system, not just bad filtration. Water damage more often kills pumps or rusts lines before it sticks a injector open.

Dianahayes, you're saying the injector issue itself is more about internal failure than poor filtration... but what about the fuel quality side? If someone runs cheap diesel with high water content or bacterial growth, wouldn't that eventually cause enough carbon buildup or corrosion to screw with the injector pintle? Or are you talking about something more specific like a broken spring or solenoid problem?

Dianahayes has a point but I've seen water damage lock up injectors too. Had a fleet truck come in with slime in the tank that blew past the filter and seized a pintle solid. Cheap fuel with bugs or water will cause just as many injection problems as a broken spring will. Debris doesn't always kill the pump first, sometimes it just hangs out in the rail and waits. Both sides are right depending on what kind of crud you're dealing with.
