About This Product
MCS custom chrome fuel valve kit. It converts the through-the-tank petcock on 1935-1965 FL models with OEM dual fuel tanks. The kit includes a modern-style valve and an adapter for rubber fuel line. The chrome hardware suits Panhead, Knucklehead and Flathead-era tinware. It bolts in place of the dated original design. Fuel flow is more reliable and future maintenance is easier.
Manufacturer part number: 504055.
