NHRA tech rules; fuel line

Aeroquip makes a silicone fuel line that uses "push-on" fittings that utilize no clamps.

I believe it's called "Socketless" line/fittitngs, by Aeroquip.

I don't run at NHRA tracks (none in my state.) I built a fuel system for my car from a similar parts collection, with Gates hose (silicone outter) and, half-inch (#8 A-N) "push-on" (barbed) fittings. The hose and fittings came from GRT Race Cars, a local dirt track chassis builder with an impressive reputation. The salesman there told me that "push-on," non-metalic (Gates) hoses is all GRT uses, and that dirt track racing is the most demanding test a fuel system could be submitted to. He said that he's seen cars running around the race track, with the fuel cell having fallen outside the car, bouncing around on the ground, being dragged by this hose/fitting combination (unbeknownst to the driver,) and that eventually, the hose would pull apart before it would separate from the barbed fitting (with no clamp.)

What I am asking is: What is NHRA's ruling regarding this type of setup. I have read, elsewhere, that NHRA does not consider this to be "rubber" hose, but I'll believe that when I hear it from an NHRA TECH.

As I said, I don't run at NHRA strips right now, but that doesn't mean I won't, in the future.

As you all know, you can read ANYTHING on the Internet, so, I'm asking for information from a person with firsthand knowledge about this.

Any information will be appreciated.
