Question about 1996 GMC Sierra
Basically, no matter what contaminated it, you gotta clean it out. even water. worst case is drop the tank, empty and flush with clean fuel. replace tank, replace all filters, disconnect the fuel line at the engine end and turn on and flush with clean fuel... and hopefully your fuel injectors survived. if just water, they will probably be fine. if something like sugar was dumped in your tank, that is not fine. change your oil and oil filter too. and cross your fingers.. in fact change your oil again after one day. and cross your fingers again... maybe even a third time... and you know what to do next ... sugar is bad bad bad for engines. if it got in the crank bearings cam bearings, into the push rods, lifters, on and on and on, its like pouring sand inside the engine.
