i accidentally put bdp in my bosses 08 Denali diesels fuel tank. WHat DO I DO?

Bdp?

SOME KIND OF EMMISSIONS ADDITIVE WHICH SHOULD HAVE GONE SOMEWHERE OTHER THAN THE FUEL TANK I GUESS. tHERE IS A LITTLE BLUE CAP /FILL HOLE WHERE IT GOES/ BUT FOUND THAT OUT TO LATE!

I have no idea what it is or what it contains. I can't locate it on a web search.

Oh, sorry, i just found out it was DEF or diesel exhaust fluid I put into the fuel tank. Any help would be appreciated!

No worries:

how do i get this def out of fuel system?

how much did you put in?

2 and 1/2 gallons
Once we realized what I did, we drained most of the tank and then added 10 gallons of diesel. We changed the filter and it still wont start.

was it run with this stuff in the tank?

Oh. I just read more of the fact sheet and this stuff is supposed to be injected into the exhaust stream before the catalytic.

yea i know. any ideas?
THe truck started, drove a few feet then turned itself off.
now it wont start again.

It is proberbly in the injectors and pump, i would back off all the injectors and bleed the system at the injectors, (cranking in short bursts) to remove this from the system, try this.
