On/Off Fuel Valve for 5.5 gal wing tank

Post by GWestphal »

I bought a 11-0660 fuel valve from American Champion and will be using it for the On/Off 3/8" fuel line coming out of the 5.5 gallon RH wing tank. One end has a male 3/8 NPT thread coming out. The other end has an internal what ( I BELIEVE) is a 3/8 NPT female thread and ACA shipped an adapter that reduces the female thread to a 9/16" -20 thd compression fitting for the 3/8" fuel line. The adapter has a 3/8 NPT external thread on one end that goes into the valve. Does anyone have a print of this fuel valve and could tell me before I screw in this 3/8 NPT adapter that the valve is for sure a 3/8 NPT and not a 5/8" machine thd. Bill Pancake mentioned a while back that some people were threading in 1/4 NPT fittings into the original smaller old 9/16-20 thd fuel valves and they come up leaking after awhile. Gordy in Minnesota
