what the heck is this in my fuel?

I just cleaned my carb a few months ago cause the car sat for a while. I recently found this muddy grey substance in my carb..The fuel was Sunoco 100 octane and was in the tank for about 1 month. What do you think the cause of this is? I'm gonna remove the fuel cell and flush the whole system now..I'm assuming its something in my fuel cell causing it...

Yes, but Im thinking it might not have an element in it after seeing this, I need to check into that..Even so, why would there be this much crap in my fuel for a fuel filter to catch?

Looks like you got fuel contaminated with a plastic monomer like styrene. This happens more than one would like to see, filters will not pick this up if this is what it is. You need to get this checked out as uncured plastics dissolved in gasoline can wreck the inside of the engine by gluing the rings into their lands.

When I lived in Houston many years ago this happened with Diamond Shamrock, they got fuel contaminated with styrene monomer while in pipeline transit. It ruined a great many engines in the Houston area. Goes to show you how much they don't test what they deliver to gas stations.

Should I go complain to the gas station? How would you test this for sure?? I just redid the head gasket and internals looked fine.

Here's a picture of ethanol residue from a boat carburetor, does it look familiar?

Not really..My residue looks grey and actually feels sandy and gritty. What exactly is "ethenol residue"? I have never heard of that term.

I dunno? It is a freaking $1500 Nascar fuel cell so I assumed it would be compatible with anything you put in it...Is ethenol in Sunoco 100 octane? on a side not the carb was gunked up similar when I got it and the duda always ran straight C16. I dont know what to think at this point..

This pic shows the first time I noticed it all crudded up when I got the car it was a similar texture but all dried out..

It's the root chemical in making polystyrene plastic one of several name brands being polyester. It's used to make foams, is a common resin in fiberglass and composite structures, solid, and is made into threads for cloth and ropes.

It is pumped through pipe lines with other hydrocarbon and alcohol based fluids. They use a water slug between different materials in the line, just in case you wonder how water gets into gasoline, this is a major source.

I'm not saying that is this resin but from the pictures it looks like a plastic that is falling out of solution with the fuel and curing onto surrounding surfaces. It looks pretty hard, is it hard, soft or gooey? If you have a fuel cell which someone else indicated you did it can be that certain solvents in the fuel are melting it and redepositing it. I guessing as I'm not there just looking at the pictures, but I've seen this kind of stuff before and a plastic resin was what it turned out to be.

It is gooey with chunky gritty pieces. Feels like paper or sand when you squish it with your fingers. Do you think the foam in my fuel cell could be dissolving??

My fuel cell has foam blocks in it, used to control sloshing, but it's staying intact, just a thought. Does yours have baffling or foam?

Depending on where you are, yes there could be up to 15% ethanol. I would contact manufacturer of the fuel cell and check compatibility and open it up and see what s going on in there. That stuff had to come from somewhere. We used to run fiberglass tanks in the skiffs until ethanol came out and we found that it ate them up.

Its an ATL 15 gallon safety cell. The website says it has a molded rubber bladder..Im betting the bladder is deteriorating at this point...
