If any of the issues noted above occur with the primary filter, ie. "O" ring not seated, bowl not snug etc. I suspect the symptoms and warning should happen relatively soon after filter change. The only one I see being delayed would involve the use of an additive and the foil seal. This one might only show up when the tank fuel level got down enough for the foil to get sucked into and obstruct the fuel flow. In my case the additive could not be the issue. I don't always use the additive but when I do I cut the foil and dispose of it so I'm sure that's not gonna be a problem. In both of my cases I was well between fuel filter replacement intervals ( like 5k-7k miles). In the more recent occurrence I had filled my tank at home the day before ( high volume dealer) and had driven approx. 250 miles trouble free. First thing the next morning it happened. Now, also with this more recent one, I still have NOT changed the filters. This is my daily driver and have put on some miles trouble free. The CEL went out about by itself after about 2 weeks time. So, in the meantime I have the filters still sitting on the back floor waiting for replacement time. When that happens I plan to take the primary and open it up to see how fouled it might be.

ThanX all, the experience and help here on the forums is absolutely priceless.

I dropped the tank and did a solid inspection in there so no cardboard tops or anything for that matter blocking the fuel supply unit (which also looked fine)

Today I looked at the new pressure fuel pump assembly we installed and all stops lined up, 32mm on to also make sure that was tight and checked the drain plug. All seemed ok but still not convinced the pump isnít the problem so I picked up another brand new from Ford. Inspected that thoroughly and may install tonight or tomorrow unless I got other advice. If itís not a freak bad new pump already installed the problem will then have to be coming from under the hood. Worst case is high pressure fuel pump has gone/is going bad that could also explain this

Conclusion to this saga

Just to update and hopefully help others searching for this problem. Worst case scenario on this 2014 F350 fuel issue..high pressure fuel pump has gone bad and if you look at YouTube videos, you will see how bad this problem can be. The high pressure fuel pump starts going and the metal bearings inside start rubbing metal on metal. Metal shards then go to the injectors and keep them from pushing enough pressure to the engine. The entire fuel system has to be replaced and itís crazy expensive. Ford sells a kit which right now are on backorder until January! Anytime anything gets into the fuel line (water, DEF fluid) this will have to be done. 6 of them currently at my local Ford for this. 34 hours labor according to Fordís service program plus kit together is almost $8k!! Awful. Truck is getting dumped and replaced
