NHRA fuel check
 
What are you Stock and Super Stock racers using for the required fuel check? New to Stock racing.
Thanks

Just curious but what is the devise being used to check fuel for
chemical content or diaelectic spec.?

So you don't have to pull the fuel from a fuel line under the hood?

This looks like it just pulls a sample from the tank.

Thanks,
Bill

That one mounts on the regulator. Push in and the fuel comes out of the tube. Release and it stops. Looks like a nice way to do the job. As far as I know you have to take the sample from under the hood.

"Pumps/Valves: Cars equipped with carburetor(s) or nonelectronic
fuel (EFI) systems but with mechanical non-OEM fuel
pumps must have a quick-action fuel-shutoff valve within easy
reach of driver and located in the main fuel line between the
fuel tank and the carburetor and/or injectors. Fuel recirculation
systems not part of normal fuel/pump system prohibited. All
cars in Stock, Super Stock, Competition, and Pro Stock must
be equipped with a positive-lock drain valve located between
the fuel tank and the carburetor(s) or fuel injector to facilitate
removal of fuel samples for fuel-check purposes."

Will pump gas fail?

J.R. Haddad 02-06-2018 09:01 PM

Re: NHRA fuel check
 
Is it on the approved list?

Re: NHRA fuel check
 
approved ? wow, this shouldn't be rocket science.

Ed Wright 02-06-2018 10:13 PM

Re: NHRA fuel check
 
The fuel has to be on the approved list. What's the big deal? They have to have a known good sample for comparison. They need to know the specific gravity, etc. Pump gas is all over the place. If you have not checked that stuff, it is easy to understand you not knowing that. Those tech people don't have it all that easy. I have done that at a local series. I try to work with them, and not give them any crap. Just follow the rules. They did not write them.

Mike, a little Velcro strap goes a long way using the lever type valve safely....

Where would the approved Fuel list be found? I looked and didn't seem to find it. Thank You Kenney Kelley

Yes ! It has alcohol in it.

Is there an advantage which blend over another?

GallopinGhost 02-07-2018 10:56 AM

Re: NHRA fuel check
 
Sorry. Thought you were talking about the valve needing to be approved. :D

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

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.

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...

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.

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.
