Help if you had this problem
I just experienced recent breakdowns and incompetant mechanics so I decided to take operations in my own hands. My fuel system had been fouled up due to that new low sulfer diesel fuel which eats away at the painted coating inside the fuel tank. I just replaced the tank, fuel pump anf filter , the truck now runs dependable(it used to cut out after 45 minutes) however I ended up with an engine miss. I've been informed by a friend that the sump assembly has two additional filters that are not servicable ontop of the sump screen, is this true? Is it possible that something made it to a injector and clogged it? I'm getting ready for a "for sale" sign . I'll be running fuel oil from now on, the EPA is pushing a fuel that has not been tested for its effects on fuel systems.

Welcome to FTE, what year is your truck? Our fuel tanks are plastic, there is no paint . As far as filters inside the tank, there is none, other than the screen. Change the filter on top of the engine, could be a little water made it in the bowl.

From his profile, he has an E-series van. I don't know about the tank, but have heard of larger trucks having trouble with the fuel tanks and the liners. As far as a miss, don't know that a fuel restriction would do that. Tell us a little more about what is causing the miss. Is it constant, only during heavy acc. or even at idle??

I'm not sure about additional filters in the pick up tube, buy you can disconnect the fuel line from the back of the pump and use a shot of compressed air backwards through the line to see if you can blow something out of there. If you see something on the top side of the screen then you know where you stand.
I don't think you need to worry about a clogged injector since the filter should catch anything before it makes it that far.

ohm out your injector harness, you could have a burnt wire under the valve cover, check your wiring harness were it runs across the left valve cover for chaffing. if its missing then you need a scan tool and check for codes, also run a cylinder contribtuion test to isolate which cylinder is at fault.
on a side note the farm fuel/heat oil is going to be ulsd by the end of the year. it has no "fuel system killing" effects despite what your friends tell you. if that was the case then every diesel vehicle would be on a tow truck with the same problem.

ok, so are you running biodiesel or ulsd? biodiesel will clean the fuel system and clog fuel filters, it will not eat away the inside of your system, if thats the case then your "radiator shop owner" would also be rich after continuous relines every few months. if this fuel is strong enough to strip paint and eat away steel coating then ask him why are our injectors not falling apart? they have internal orings as well as external o-rings, why then are they not falling apart, just fuel tanks.....

i also cant see why, even if the fuel ate your tank, the truck would die after 45 minutes of driving? what did the inside of your tank look like? and why was the fuel pump condemed? the diag methods arent making much sense here

I would bet the air through the fuel lines into the tank has cleared up the screens enough to make it better, but not perfect.
Here is the link to the intake directions ITP provides. They have some pics in the directions that will help you see what I am talking about. If you take the mixing chamber out you have to put something in line to protect the fuel pump/operate as a gross decon of the fuel. I just used a cheap inline filter from NAPA. That is what the guys from Diesel Innovation do. (Dennis used to as well, but he has upgraded to a better (finer than the stock setup) filter)

Good luck and with that...I have a pickup, not a van so they might not be the same...
