No pun intended; been in the sport for 45 years. Why just add more work when an electric pump will just do fine and easier.

Handover fist, merely stating my experienses at the track, most of the tech people are aware that the majority of racers are under the hood for their fuel samples. Now could I have simply gone ahead and taken a sample out of the cell...yes would anyone seeing what I was doing had said any thing IDK. I felt it better to be up front and explain the situation before hand than to try and explain my actions after the fact. BTW they did have one of the tech guys come over and observe me getting the fuel sample, do they do it all the time I don't know I fixed my over sight and went on. The point I'm trying to make is using what is readily available, easily installed with no drawbacks what benefits would there be to utilizing the belt driven pump?

If you still want a fuel cell under the hood, you still have the option of running Pro Mod and be legal!

Was just kidding!

Fuel valve on the cell for drawing samples?

You must be racing at IHRA because NHRA does not allow that. The fuel sample must be taken from a valve located in the fuel line between the fuel cell and the carburetor.

That is not exactly how it reads...mentions nothing about the fuel line.

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.

Well read it how you want, but the NHRA tech guys want it taken out of the line between the tank and carb or injectors. Taking a sample out of the fuel cell drain will only work until they see it. And they do randomly watch. But back tithe subject, in a performance based class (SS) why would somebody want a belt drive anything? I don't care what anybody says, a belt drive fuel has to take horsepower. Has to. And with horsepower coming at the premium it does, I dont want to waste any when a good electric pump works fine.

Hand, You may read the rule about taking a fuel sample one way, but if you do it don't be surprised if they ask you to change it to under the hood. You may have a chummy tech guy in your div that goes along with your tank valve, but you might go to another Div and find they don't like it. There are several reasons for under the hood. If the hood is open sometimes I've had them check my carb to see if it is legal. They also check the sealing of the carb and engine when you set a record and when you do the back up run. Most of the time a tech guy meets you as you pull up to the scales with the circled R on your window.
A Tech guy couldn't do those checks in the trunk or at the back of the car. They also want to see the actual line the fuel comes out of and a fuel cell under the trunk is not an area they can do a good visual check. There are some guys out there that will cheat up on fuel and that is who they are looking for. I have been told of hidden fuel sources, both for running the car and for fuel check purposes. They run an oxy fuel and check with another. If you have something odd or out of the norm you could be looked at and scrutinized a little closer. In other words(street English) you can be hasseled. I'm not saying it can't be done I'm just telling you how a NHRA Tech guy thinks and works.

In addition to Adger's statement, I have also been told that the valve should be visually in the engine compartment, before or after the regulator, and in the event of not using a fuel regulator, before the carburetor or Throttle Body/fuel injection rail.

Yep, it's fun to get a fuel sample on a SS/Modified or Comp car that requires Dzus fasteners to the released for the hood removal!
