Black metallic looking stuff in fuel pump filter & sump
My son called me today and said his truck stopped running about an hour or so after he fueled up. He got the truck towed home & torn down & asked me what would cause this black metallic looking substance in his fuel filter/fuel pump sump in his 2004 Dodge Ram truck. He said it was only in the in-tank pump/filter/sock sump and felt a bit gritty, but the tank looks clean. He fills up his truck every two weeks with gasoline so it shouldn't be old fuel The pump is 3-4yrs old and is a VDO pump. Below is the pictures he sent me.Last edited by TooMany2count; 02-03-2019 at 12:39 PM.

Over time, contaminants from water and condensation can get rancid and form a sludge looking muck. Odd that it's only in the pump.

shows that the filter and sock workedBy popular opinions-just a grumpy old man key board bully--But really, if you are going to ask for help on an internet site, at least answer questions about what you are asking about-----

Just a wild thought came to mind looking at that gunk...could it possibly be valve-grinding paste?
Does he have anybody out there with a grudge against him?
I may very well be miles off the mark, but as I say: just a wild thought...johnboy

He may have fueled up as the tanker was making a delivery ( or shortly thereafter) could'a pumped some crap from the station tanks right onto the truck.
