Say Good-Bye to Pry Bars
Pro-Werks provides another new improvement for racers and rodders; fuel cell users can now easily upgrade from the less than desirable, original fuel cell manufacturer provided troublesome flip-latch style filler or bail cap - to the popular Easy Turn Fill Cap Assembly from Pro-Werks.
6-Bolt and 12-Bolt Fuel Cell Assemblies
This Fuel Cell Cap assembly is a simple bolt-on installation as a replacement, or right at home on new custom tank fabrication, and includes the necessary stainless mounting hardware with the Buna flange gasket.
The lightweight, non-vented cap features positive grip finger notches that are easy to get a hold of. Prime 6061-T6 billet aluminum is precision CNC machined into a lightweight, attractively designed cap; featuring quick-start coarse threads with a special starter nose to accurately lead the cap into position - a very nice feature when you are taking care of business in the dark. Each screw on cap is fitted with a Buna O-ring; positive sealing and "radially squeezed" to hold the cap secure.
Keep Your Cap Close
The signature Pro-Werks Fuel Cell filler cap also includes a built-in lanyard boss, enabling the use of the optional lanyard chain to conveniently keep the cap close by - if you so desire.
Great Caps. Great Colors.
To compliment the color coordination of your project, the caps are finished off in Pro-Werks Brilliance anodized colors in your choice of Black, Red, Blue, or beautifully Micro-Polished aluminum – the finishes are impeccable!

Frequently Asked Questions
Q: How much do I need to tighten a fill cap?
A: It is not necessary to bottom the fill cap into the bung−just adequately seat the O-ring. The radial squeeze action on the O-ring creates a positive seal and helps prevent the cap from coming loose.
Q: What should I use to lubricate the Buna O-ring?
A: Applied periodically, a light coating of Dielectric grease has proven to work well as an O-ring lubricant.
Q: Is Buna rubber compatible with my fluid?
A: Buna is a synthetic rubber compound suitable for use with many fluids. Buna components may need to be replaced by a material compatible with the specific chemistry of some fluids.
