What is it that is measured in the fuel check and how do they go about it?

Fellow slow stocker. The one and only time I had a fuel check issue was after swapping from Sunnoco Blue to C12..........cell had foam which caused my issue.......foam gone......issue gone.

Your 258 rocket ship should pass with flying colors like mine with c-12. Don't tempt fate with a rusty fuel tank if you are not using a cell. Only thing to watch out for with C-12 is run carb out of gas each and every time you are done for the weekend.....C-12 gets crystaline in the bowl and junks everthing up in the stock BBD, do the same with the optional 2HP penalty holley 600 with the aluminum intake setup. Just kidding.

They are checking the specific gravity and temp mostly as far as I can tell. So if your fuel is reasonably fresh and the temp isn't way off(super chilled) you should pass.
