Purchased by myself? NoHas anybody here actually gotten "bad" fuel?
I've seen it in vehicles pulled into the shop though. Most of the time the "bad" is water and the algae that can come with it. Occasionally it will be a waxy lard type substance that I assume is the result of a bad fuel or bio mixture.
I built a fuel polisher that uses rubber hoses, an old water separator, and a used carter lift pump off a cummins isb. I'll add biocide and fuel cleaner to the tank, stick the one hose into the tank's bottom, and leave the other hose in the filler neck. Let the thing run all day and then throw the fuel filter away afterwards.
I've never looked inside the tank after I'm done to verify the results, but every truck that I've used it on had no evidence of a problem afterwards.
