Ngl, I used to think those aftermarket fuel pressure sensors were a waste of cash.

I was on a road call for a 2012 Freightliner Cascadia with a hard start near Flagstaff, and after checking everything else, I swapped in a new OEM sensor from my truck and it fired right up. The cheap one I'd put in six months ago was giving a good reading at idle but dropping out under load, which I only found by hooking up my laptop and watching the data live while my buddy cranked it. What's your go-to brand for sensors now, or do you just stick with factory parts?

Doubt it's ever that big a deal for most guys. You just got unlucky with a bad part. I'd still run the cheap sensor and just keep a spare around.

Jake_owens is right, a bad part is just bad luck and a cheap spare fixes it.

Yeah, the "cheap spare" idea is solid. I had a coolant temp sensor go bad on the highway last year. Grabbed a cheap one from the parts store just to get home. That was two years ago, and the thing is still reading fine. Sometimes you just get a Friday afternoon part, and the next one is totally fine.
