Awhile back I posted about the search for a better inline 5/16" fuel filter thinking the one I had wasn't up to the job. Some back info includes that I have a recent / new fuel tank ,filler neck , line , and fuel pump. I changed needle and seats as well , going with the best quality ones I could but of all the places that I didn't think to look or change was the carb inlet nuts. It seems that after the engine has been run and shut down the fuel is not covering the inside of the nuts and condensation can form if the car sits long enough term in a humid garage. I'm told that the present day fuels can absorb water as well(?) which can also be deposited after fuel drain back or evaporation. At any rate , I found rust inside the rusts , the pictured one being the cleaner of the two. Hope this helps someone because I was getting pretty P.O.'ed trying to get to the source and also stuck floats are not only embarrassing but needlessly attract the local law enforcement officials when you try to clear out the flooding carb at high rpm.

Honestly pal, That is NOTHING compared to smoe of the stuff that has been coming into the shop. This gas is terrible! Just 2 quick examples: A fella came in and said he had just bought tis edelbrock new and it started running rough. Well, sure enough it was stamped july of 2017 and it had a 1/4 of jelly/corrosion inside. A corvette tri-power came in last week, it was eating the bowls away, and we had to machine aprox. .015 of the metering block side of the main body to get to a true flat surface. For all reading, PLEASE DO NOT LEAVE THIS JUNK GAS SIT IN YOUR CARB!! The guy I get my Gravely tractor parts from puts an inline shutoff valve on every thing that comes in his shop. No matter why it came to his shop. He tells the customer to run it out of gas every time they put it away.
 
Is there brass nuts? That would be my thought to control the rust.

Nice find....
 
And i just straightend out an eddy on a 70 impala. Dirty. Crap fuel.
The holley i was having trouble with wasnt dirty,but maybe a little gummed up in the metering block.
All in the matter of a week.
I do believe in sea foam to at least slow down the effects of the crap gas.
 
Love my thermoquad with plastic bowl and brass floats. But yes, the fuel will screw up fittings.
 
...….I found rust inside...…….
Does it get through the filter or do you not use them?

I've posted previously that I've used Stabil in all the fuel for my '08 boat since new. In 2016 I pulled the 2300 off to clean it out. With 8 winter layups for 6 months each and the seasonal usage I expected some crusty mess. Opened it up and found it didn't need to come apart.
Since I finally put the cleaned up gas tank in the Barracuda, it's getting Stabil too...…. whether it likes it or not!
