Sorry. Thought you were talking about the valve needing to be approved. :D

as said protecting the lever or button should do the trick.

Re: NHRA fuel check
 

And, most of it is crap anymore. My 454" Suburban has started to get a little spark knock on 87 octane pulling the trailer this past year. Either go to 89 octane, or de-tune it some. I dyno tuned it on 87 octane in 2009. Been fine until this last summer. Had some customers with premium fuel vehicles (Corvettes, etc) starting to hear their's ping some on 91. Hard to find 93 octane around here anymore.

If you have a Pure Stocker, NHRA rules should be no issue anyway. :-)

Tow with a 94 beefed up Caprice wagon.
Iron Head LT1, 87 Bryan Herter Performance Tune with no problems.

Towing over Appalachian Mountains fill up with 93
Flatter land routes such as Capitol, MIR, Cecil 87, etc works fine.
Hot days use 89 or 93.

Since GT, CM or Stock require approved fuels.
Own a home in Suburbs.
Considering buying about 10 cans of Sunoco 260 GTX for a season.

How and what are the best practices to safely store this fuel?
I know my wife will be concerned.

Re: NHRA fuel check
 

Ed, agree that pump gas is p*** these days. However, is there a chance carbon is building up? Years ago, I put a head gasket on my wife's Cavalier. (Cars w/aluminum heads and iron blocks should come with head gaskets in the glove compartment...) It had been pinging on 87. There was a huge amount of carbon on the valve heads. Cleaned it off. Never pinged again.
Sorry for the hijack.

Dan, as I remember, years ago guys were putting various forms of rocket fuel (Hydrazine? I don't remember.) in their gas. Fuel check stopped that. Pump gas got caught up in the fray. I knew a guy with a 273 2 bbl U/SA car (Mike Smith rip) who ran pump gas until then. Race gas increased his racing budget about 50%. lol But that's another story...

Re: NHRA fuel check
 

YEAH that is my problem too !!
Going to Stock will be $55 to $100 a day !
Depending on how many runs that day.

Been wonderful filling up the 23 gallon tank with 93.
Works fine for my combination.
Pure Sunoco did not increase HP over the street gas.
Car loses about 5 lbs per run !!

Already have an 8 Gallon tank built.
Will have to add a petcock to drain the 93 out for Bracket racing.

Re: NHRA fuel check
 

Maybe, maybe not...not all pump gas has ethanol blended in it. Last year at the SportsNationals I mistakenly added some non-ethanol/Renegade mix in the El Camino. Fuel check was not a fail...tester just said it was pretty flat and offered to check my jug. It was only then I realized what had happened.
