Default Re: belt drive fuel pump in SS

As most good racers know the rule book is laid out in a "Stacked" form. That is why the rules pages for Super Stock classes seem to get less and less as you move through the rule book. Super Stock goes all the way from Section 9A (SS) to section 9G (SS/MX)
The GT/Truck section is 9C. At the top of the page under GT/Truck you will see: Requirements & Specifications for GT/Truck classes are the same as those for GT/Car classes- section 9B with the following exceptions.
When you read section 9C and nothing is mentioned in it about your area of interest you move back to the section 9B SS/GT and see if you can find what you are looking for. If it isn't there you go back to section 9A Super Stock.
The way I read an older(2009) rule book (only one I have here at home) I find that there is no mention of Fuel Pumps in Section 9C or 9B, but alas I find what I'm looking for in Section 9A under the ENGINE:1 section under Fuel System.
It says "Any Mechanical fuel pump and/or maximum two electric pumps permitted." Then the Fuel system goes on to tell how the electric pumps must shut off and you are allowed one cool can and you only are allowed 12" of rubber line connection. The last thing tells you to see General Regulations 1:5.
In Gen Regs 1:5 we find Fuel Systems again. It has some sub sections IE: Location, Tanks, Lines, and Pumps & Valves, Fuel/Air & last Alternative Fuels.
In the Pumps & Valves sub section the first line says that cars with non OEM pumps must have a quick action fuel shutoff valve within easy reach of the driver. The shutoff must be between the tank and the carb or injector.
After reading the rule book (my 2009) I would say in 2009 you had a real good case for mounting a belt driven fuel pump in SS GT/Truck class.
You need to read the current rules in a current book and discuss them with the Div 4 Tech director. That is how a tech person and racer should read and follow the rules. the only other thing that needs to be checked is to see if that is mentioned in the Tech directors Policy and Procedures Manual. That is a rules clarification book that we don't get in the mail. They do...
I just happen to know where there is a 2006 copy of the NHRA TECHNICAL POLICIES & PROCEDURES
Section 1.8 deals with fuel. It says nothing about Mechanical fuel pumps in SS. It does have a section about fuel check. Remember you have to give a fuel sample, creative plumbing, maybe.
Larry, You have a choice of doing it and not saying a word. Just show up and race. Or check with the div. 4 Tech to be sure.
Well, that is about it...
