As noted in my previous post, the fitting isn’t the same as a Chrysler so that won’t work. And I don’t think the hole through the handle on the motor will accommodate a Chrysler male fitting.
I am intrigued by Frank’s thoughts that it could be an air chuck fitting – it would be just like Oliver (and Champion) to do something like that. Looks like they have all the measurements on the side-bar of his link. My only concern would be how the seals hold up to our modern fuel.
EDIT: For grins I tried a size "M" air connector from my shop: it did seem to fit, though I didn’t test it for leakage. It felt like it latched on well but when I wiggled it side-to side it was a little wobbly. A quick inspection showed the end-opening is 30-thousandths larger than the Oliver one, so that may need a bushing. And I don’t know how the air connector will hold up to fuel instead of air going through it. It’s worth someone doing more research, especially since the "M" connectors can be found at Home Depot, Harbor Freight, etc… Kudos to Frank for spying this possible connector resource!
