I was wondering if there was a source for the thread size/pitch on the '70's R fuel tank fittings. A hose/fittings company says the male tank fitting is M20 x 1.0. I'm trying to find a solid end cap to be able to etch/tank seal. I see M20 x1.5 but no 1.0. Is this unique to BMW?
Any help will be appreciated.
