Everyone has been concerned about modern fuels. Here is more proof. The build is less than a year with newly rebuilt carb. It started idling rough and became inconsolable. Pulled it apart today and scooped out some jelly. This by no stretch is all of it but quick scoops for illustration
When the Ethanol evaporates we are left with corn syrup
My question is why the solids are in the fuel anyway?? Running the trucks on purely non-ethanol is surely the best way for them but the fill price puts things into painful territory! Currently researching attempting to find a reasonable middle ground...

I have no idea what goes into the ethanol that causes this. When I first experienced it was in a little container I put gas in to clean a few small parts. There was about 1/2 inch of gas left in the bottom of the container that sat for 2 days outside and when I went back to get it only JELLO was left.. I never let any of my engines sit for more then a week without running them. Modern cars have sealed fuel system so it doesn't happen to them. This was another reason I put my extra Y block on a cart to keep it running.. Makes you wonder what is happening in the tank?
Is that the fuel or is it a contaminated additive? Sorry about that for you. After all the work that goes into a project and then have it sabotaged by the oil companies it definitely troubling.
I recently pulled my carb & cleaned it out due to the exact issues you describe. Didn't find any jello, but the crap I drained out of the secondary bowl looked more like bourbon than gas. I also drained my tank & refilled with non-ethanol gas. I have a thread over in the 335-series engine forum on some of the issues I've been having with the motor. A machine shop guy I talked with even said ethanol fuel can cause intake valves to stick. Hadn't heard that one before, and have been running regular pump gas in my 79 K30 with a small block for years without any issues.
I take it you guys that are having this jell issue dont run the motor much or drive the truck much either?
When I was rebuilding my 81 F100, 4 year cab off frame, I did not want any fuel in the tanks as I did not know how long it would be sitting but I wanted to be able to move the truck for cleaning the floor. My fix was a small fuel can, about a gallon, set on the inner fender and a long hose to the engine mounted fuel pump.
Truck did not sit more than maybe 2 weeks between starting and never had any issues like this.
Even now that the truck is on the road for 4+ years it may sit for 2 weeks between use as I use it for weekly trash runs to the dump.
Anything that may sit for a long time I run out of gas, fuel cut off valve, and if there is a bowl drain I drain it.
Have not had any issues with the emergency gen set or the power washer doing it this way.
As a side note have you tried getting fuel from a different brand station?
Maybe they add something that causes that and is that the normal 10% we can get everywhere?

Wow this has definitely got my attention. Can you guys share what fuel grade and brand, U.S. or CAN. You are using (A local dyno shop claims that U.S.gas makes more power than CAN. Gas so if that’s true then it must be different) and if you are using the same station all or most of the time.
I recommend never fuelling up if there is a tanker on site filling the tanks as it stirs up any sediment that may have accumulated in the tank. Also if you’re only using the filter at the carb I suggest adding a good quality secondary filter.
