The Wayne 66 was the second “tandem pump” offered in the Wayne 60 series. Built between 1937 and 1940. The “Wayne 66” model was built to better accommodate gas stations with smaller islands and still be able to offer multiple products and grades of fuel. This pump had 2 hoses and could dispense 2 different products. Several “Wayne 60” parts will fit the “Wayne 66”. However, Since this pump was modeled after the “Wayne 60-A” there are several parts that won’t fit. If you are needing parts, please call us so we can get measurements and can be certain the parts will fit Correctly.
