Rochester Gauges 6580-00164 (6580-164) Fuel Gauge for Boston Whaler

The 6580-00164, also referred to as the 6580-164, from Rochester Gauges is a senior, fixed length model designed to fit the 63 gallon Florida Marine Tank inside many vintage Boston Whalers. This gauge is manufactured for us by special order and it comes as it was originally designed along with (4) 1⁄4"-28 x 9⁄16" mounting bolts and a Buna-N gasket.  The original aluminum bezel dial, P/N 5002S00062 aka Dial No. 5-62, is not included with 6580-164 and is available separately, or as a different variation of this part from the drop-down menu.

IMPORTANT NOTE:  Most vintage Boston Whalers have a fuel tank flange that is not threaded for the (4) 1⁄4"-28 x 9⁄16" mounting bolts.  Instead, it requires the gauge to be mounted with longer bolts and nylon lock nuts.  Because of this design, we have sourced the necessary parts and added the following bolt kits:

• Bolt Kit BK-1 includes (4) 1/4"-28 x 7/8" bolts and (4) 1/4"-28 nylock nuts, with all parts being high-quality zinc plated steel.
• Bolt Kit BK-1-SS includes (4) 1/4"-28 x 7/8" bolts and (4) 1/4"-28 nylock nuts, with all stainless steel parts.

The gasket that 6500 series gauges is part number 0015-00004 and it is a flat ring gasket.  We also offer another Rochester Gauges gasket that is precision cut to seal the underside of the gauge.  This gasket is far more effective at sealing the tank while also keeping debris and moisture from getting trapped between the flange and gauge head, leading to premature corrosion.  It is part number 0015-00079.
