Pro-Werks provides another new improvement for racers and rodders alike. Fuel Cell users can now easily upgrade their Cells from troublesome Flip style filler or Bail cap, to the popular non-vented, Easy Turn Fill Cap Assembly from Pro-Werks. This assembly is a simple bolt on installation. The Billet Aluminum Fuel Cell & Filler Cap is a Pro-werks specialty.

The positive grip finger notches of the Easy Turn Caps are easy to get a hold of. This design is another Pro-werks innovation, and is appreciated by everyone who uses them.  Featuring quick acting coarse threads with a starter nose to accurately lead the cap into position. Each is standard with a special positive sealing " radial squeeze " Buna O-ring, which also holds the cap secure. The Pro-werks Fuel Cell cap also includes a built in lanyard boss feature, enabling the use of the optional lanyard chain to keep the cap close by if you so desire.

Easy Turn caps are available in a large selection of Pro-Werks Brilliance Anodize Finish colors or beautiful Micro-polished aluminum. The bung of  this assembly is also available in your choice of two anodized colors, Silver or Brilliance Black. The extensive selection of color combinations gives you the opportunity to match your individual style. Includes all the necessary stainless mounting hardware and the Buna flange gasket.

Both the cap and bung are precision CNC machined to exacting tolerances, of light weight billet aluminum, right here in the USA ( Mears, Michigan ).
