So my 7.3 just came back from getting its dmf to smf swap, put my new pedal assembly, just a lot of winter time things that needed addressed. I was having an issue with the truck stumbling off wot 1/50 times and thought my pump may be shot at 80k. Tried the atf trick and while doing this and a new fuel filter I noticed air intrusion and could not figure out where it was coming from.
@Thewespaul had been walking me though some stuff to look at, I had deleted the entire factory supply line from the fsv and replaced it with rubber line and still some air but almost at random. Was going to delete the fsv and try to isolate whether the tank of fsv was to blame [and already ordered a new fsv and 50' of 3/8 and 5/16 diesel hose..... and this morning something unexpected caught my eye. While going to start on things. If I tilted the facet forward it looked like no air but towards the rear bumper there was air... and it looked wet and well the video tells the story..
So I guess if you have any odd issues with your facet pump whether you mounted it or not yet in my case cause I have so many extra things there I'm fabricating a mount for all 3 and it's not that high on the list, but check your pumps..
I'm taking it off now to see if its cracked or what happened will post that shortly.
