 2" Hose Billet Cam-Lock 1/4 Turn Fuel Fills - Non Vented

When it comes to style and function nothing screams "Cool" like a real aerospace jet airplane styled fuel fill.  Until now the only place you would find this high tech type of fuel fill would have been in a Formula One race car or the likes of a jet airplane.  Now thanks to the folks at Hardin Marine that same technology has now been made affordable to all.  CNC crafted from 6061-T6 billet aluminum and clear anodized for protection against the elements. These fuel fills are extremely easy to use with no threads to deal with, just flip the lever, twist 1/4 turn left or right and the unit is either installed or removed.  A safety chain is included so as not to misplace or drop the cap overboard.  An additional fuel vent must be used. Fill is 3.45" wide. Available in standard powdercoated colors. See installation instructions for detailed measurement specs.
