I’ve got a 2003 7.3 PSD, and I’ve recently started smelling fuel in the cabin when the AC or air is on. It’s especially noticeable at idle or in slow-moving traffic, but not as much while cruising. I’m guessing there might be a fuel leak. Where should I start looking?
Check for leaks on the steel lines in the valley; they sometimes develop holes from vibration. Also, inspect the area where the lines pass under the GP relay bracket and check the rubber seals at the ends for wear. Don’t forget the filter drain.
I’ve been dealing with this too. I can’t smell fuel anywhere except in the cab, and only sometimes. Thinking it might be the fuel bowl, but I don’t see any leaks.
