Sugar in gas tank - 2000 GMC Jimmy

Empty the tank of fuel and clean out your fuel filter and drain down the fuel pipe leading to the engine

it has been shown that sugar is not dementrial to the running of an engine
it's basic chemistry is hydrocarbon the same as oil, fuel so it will dilute out in a few tank fills ethanol os refined sugar with most sugar cane farms now converting to ethanol production
if you are still not assured , then remove the line before the filter and run the pump to pump out the tank
fit a new filter and fill the tank
replace the filter at around 1/2 tank

Did you have the sugar cleaned out of the gas tank? If not, you don't have electrical problems. You have fuel problems. The sugar gums up everything. The fuel pump, the filter and the injectors. Did two cars from the same family. Had to replace the fuel pumps, filters and all the injectors (couldn't even have them professionally cleaned). Cleaned out the tanks and all the fuel lines. Their insurance covered the parts and labor.

if someone put sugar in gas tank and you havent tried to start it then your OK you just need to drop your gas tank and flush it out . If you tried to start it and it got to your engine then you have a major problem like getting a new engine

If u put sugar to a engine or gas tank. 1engine u have to take it apart or will be damage 2 gas tank have toremove tank an clean it up and the lines

First off it is a myth that sugar will destroy an engine. Sugar will not dissolve in gasoline. Depending on how much sugar was added it could clog the fuel pump sock filter. You have drained the tank, so add 5 gallons of fuel to the tank and start the engine. It will do no harm whatsoever. You may have to change the fuel filter a few times if the sugar clogs it but otherwise no harm will be done.

if it still starts then your ok.remove gas tank and dump fuel.clean out any sugar on bottom of tank.go throuh the fuel pump hole. use a water hose if needed then let it dry.fill up tank and just run it it will be ok. what sugar does to an engine [and never mind myth busters, they are wrong] ive seen it 4 times, someone in town was having fun with sugar in the tank.anyways with enough sugar in gas tank the sugar disolves in the fuel.then engine,especially the valve stems get hot and sugar becomes a molten goo on the parts,valves,pistons,cylinders,fuel injectors.only the hot parts seem to be effected. then when you turn the engine off the sugar cools and becomes hard like a piece of hard candie.the valve stems are now locked into valve guides and cannot open or close,it takes alot more driving to damage pistons and rings only a little sugar is injected on every intake stroke and its aimed right at the valve stem.one mile of driving i dought will cause problems. beware that if the sugar was poured it dry you will need to flush out the filler neck.if it was dry then very little got in the tank anyway,unless you put gas in it after sugar was added

sugar in tank goes to bottom and clogs the rest of the fuel system. If you are thinking sugar...... than it's possible that someone could have put anything in the filler to block it

It is a myth that sugar will mess your car up. Sugar does not dissolve in gas, it will just sit in the bottom of the gas tank. You will need to drop the tank and have it cleaned, and replace the in-tank fuel filter, but anything upstream of the fuel filter will be okay.

How do you know if its got sugar in it? I dought it trashed the engine unless they poured it in the oil too. Drop the fuel tank and clean it out, take fuel filter off and thro away, blow out the fuel line put new filter on put tank back in fill with new gas and an additive of some sorts that can clean the injectors and run it. Thats the best i can tell you to do.
