My 2003 4L is running fine. I'm just worried about it before we take a long road trip.
I can hear the high-pitched whine while I'm in the cab, the engine is running, and the windows are down, but not when the windows are up.
I tracked it to the low-pressure fuel pump by getting under the truck while the truck is running, just like you're not supposed to do.
Maybe the noise has gotten louder but it could be my imagination.
I replaced the pump assembly a couple years ago with a NAPA version.
Should I replace the pump again? Or is this noise nothing to worry about?
