Bates 1940-1965 Fuel Valve Conversion Kit

This period looking conversion kit for the 1940-1965 thru-the-tank gas valve helps to resolve this issue quickly and easily. The insert replaces the stock valve seat and accepts most 1/8” NPT, 1/4” NPT or 22 mm petcocks at the bottom. The rod is omitted, the crossover line can be retained. With the included cap you close the top of the tank. Now you can park your bike with peace of mind and without a gas puddle underneath.

Vacuum Operated Fuel Valves
Vacuum Operated Fuel Valves
This stock replacement fuel valve shuts off automatically when the engine is off. On starting, the vacuum created by the engine activates a diaphragm which opens the valve again. For safety reasons there is an additional conventional lever, too. The installation of this valve requires a vacuum hose fitting on your manifold or carburetor (as used on Harley models from 1981 up) which has to be installed if not present. All those who once found their bike sitting in a big puddle of fuel (no smoking please) just because of a grain of sand in the float needle valve will appreciate the additional safety of this device. With a 22 mm adapter nut the petcock will fit all OEM  tanks 1975-up and all aftermarket tanks that feature the same type of outlet.

OEM replacement fuel petcocks

Even though it is a simple component that often receives little attention, Harley-Davidson has used several types of fuel taps over the many decades that the factory has existed.

Until 1939, petcock valves with tapered pipe threads were used. This applies to all IOE models, singles, 750s and other SV models, and early Knuckleheads. The 1/8” threaded valves had only an on-off position, while the 3/8” threaded valves also had a reserve position. The outlet of these valves is always threaded for a cap nut. Connectors for flexible lines did not become available until the 1960s.

Thru-tank-fuel control

In 1940, a new type of tap was introduced for all air-cooled V-twins, with the operating shaft mounted from top to bottom through the tank. No more fumbling under the tank, where you might burn your fingers, but the bottom of the tap and the guide had to be aligned very precisely for the tap to work correctly. A special tool and experience were needed for precise alignment.

Pipe threads and metric threads

That is why, from 1966, taps with a 3/8” pipe thread and reserve position came back. From 1975, the switch to metric connection threads with sealing washers came into production and assembly as a further simplification. There are basically two types of these with differences in operation: only with lever and with lever and a vacuum nipple.
