Re: Olliver 5 1/2hp fuel fitting

[frankr]

Needless to say, those air fittings come in dozens of brands, mostly made in China. That means the seals may be different from brand to brand, as well as the physical OD of the coupling. I bought a box of Milton (USA) couplings when I set up my shop 20 years ago and most of the originals are still working. There are traces of oil in the shop air, which doesn’t affect the seals. But of course, no gasoline or ethanol. That’s a different topic. Hey, there was no ethanol when the Oliver was built either.
