SUGAR IN TANK? or something else?
My 98 4.6 started running real rough, so I changed the fuel filter and I noticed some white, very fine-grained residue coming out of the old filter. The filter didn't help, so removed the injectors and they were PACKED with the same stuff. I tasted it and it tasted sweet and was not gritty like sand. My question is this- is this sugar or does the ethanol blended gas break down like that? The truck started really running terrible after I ran it very low on gas. Truck has 250k miles.

**** someone off recently?
I didn't know sugar didn't dissolve in gas.

Pulled the fuel pump out to drain the gas and discovered quite a bit more sugar in the bottom of the tank. Thoroughly cleaned the tank by flushing/draining X3, then sucked the rest of the residue out with my air-vacuum (hooks up to an air hose, so no risk there). I'm going to go ahead and change the filter again before I fill it back up with gas and give the injectors another cleaning, too. Hopefully this solves my problems. Will update when complete.

I didn't either...Learn something every day.
No, I don't think I've pissed anyone off. Given that this truck was running terribly when I got it and started running good after I changed the injectors, and the fact that I bought this truck from a Sherriff's sale as a seizure (Felony DUI) and they used the truck as an undercover vehicle for a while I'm pretty sure the "additive" was put in the tank before I got it.
