sugar in the gas tank

I too have seen sugar clog fuel filters, fuel pumps, injectors, etc. I've never seen it turn to gum or varnish, because as mentioned it will not dissolve that way in pure gasoline.

bad news!! sugar in the gas tank-- once it goes into the cumbuston chamber it will turn into a Laffy taffy type material that will score and damage the cylinder wall.
Get everything chemically flushed including lines, injectors, pump, replace filter(wether in line or in tank).

How is it going to get to the combustion chamber? Sugar doesn't dissolve in gas, and it would have to get past BOTH the sock in the tank on the fuel pump and then the fuel filter in granular form before it could get to the injectors, then how would it get past the injectors?

I know these aren't carburated engines we are dealing with, believe me I know!
How does an injector get clogged? What injectors do not get clogged??? Small particles do get past filters- believe me I know, I do this for a living!
Here in the US more and more manufactures are using multihole injectors, at least 9 for better atomization of the fuel. Gasoline that is refined here in the US is usually really clean therefore we don't see a lot of injectors getting clogged but still I have pulled out injectors that at least half the holes were not squirting fuel.
Now lets jump accross the the world to the middle east- Jaguar ,the company I work for, used to use exactly the same type of fuel system in the cars there that they use here in the US- same 9 hole injectors. When the new Xk came came out the first problem they had over there were running rough issues. Techs over there kept finding clogged injectors due to the type of gas being used over there, yes its high octane but dirty. What Jaguar had to do is switch the cars from 9 small holes down to 3 large holes to prevent particles from clogging up injectors.
The point is- foreign objects in the gas will go through pump screen filter, in line filter and still find its way to the injectors were either they will get clogged or find its way into the combustion chamber.
Better yet TRY IT!!! it should be ok RIGHT!!!

Much to everyones dis-believe enough sugar WILL cause problems. Will it harm the actuall engine??? NO most likely not. Here is what I personally have seen it do.
01 Tundra (I know thats the first problem but still...) Came in with cylinder #1 Miss fire. Went through all the mechanical Diagnostics. check compression, fuell pressure, pressure leak down, spark Plugs, look for lose conections, check for electrical continuity, Blah, blah, blah... SO we Replace the plugs, swaped coil packs and still had a problem. Even though all the injectos were firing and the fuel pressure was good we finally tore the injector rails off to see if there was a faulty injector. Guess what was wrong with Cylinder #1... It was was packed full of Sugar. How did I know it was sugar. It was white and sand like. Oh and I tasted it.....It was sweet so I knew it was sugar. we pulled the tank were we found at least a pound or 2 of sugar...
Remedy was first to have him call his insurance to cover the act of savatoage. They did.
Drop and flush the tank, replace pump, replace fuel filter, clean all Gas Lines with solvent and compressed air, clean fuel rails the same way, and replace all the comprmised injectors.
After we replaced the pump we decided to take the old one apart. It was a good thing we replaced it because it packed full of sugar. The sock filter was also full of sugar.
Oh and now for the kicker The gas door locks on that truck and guess who had the truck last??? His brother... He borrowed it while this poor guy was in the hospital. He was having open heart surgury to correct a problem they found. It was found during his check up in the emergency room after he passed out at the wheel of his semi and drove it into a ditch....

I will try and see if my boss still has the pictures from this so I can post it up for all those in dis-belief... I believe I still have the cloged fuel injector around here some were.
As stated before Sugar does Not dissolve in gasoline.
Remember the fuel pump has to generate between 50- 60 PSI. Once it sucks the particals through the sock , Its not hard to see how it could get pushed through the inline filter. After that there is a small filter inside the top of the injector. This is were the particals basically get stuck and back up. Thus causing a clog....
NOT related to sugar in the tank here is another injector issue I personally had
Now in one of my own vehicals (99 K2500 suburban W/454) I had a clogged injector issue from the gas going bad. I found this out using a scan tool while trying to diagnose a misfire code. The vehical was wrecked and sat nearly a year. It was not started during that time either. The Gas basically breaks down and caused a gum like varnish to form inside the injector. 3 of the 8 Injectors were stuck in the closed position. I started cleaning them with some break cleaner to clean the brownish colored deposits from output side of the injector. I then energized them and blew high pressure shop air through them from the outlet side of the injector out through the inlet side. This forced the clog out since it could not pass through. While energized I flushed them out with break clean and shop air. Since I was already in there I took all the injectors out and cleaned them in this fashion.
****I MUST WARN ALL OF YOU**** Injectors must be properly energized... If you reverse the polarity You may damage the injector.... ****IF YOU DO THIS, YOU DO SO AT YOUR OWN RISK!!!****
