Good point. The last 2 or 3 fuel pumps were Asian. I thought that was the reason. They should have adapted to the newer fuel formula by now, but only if they care.
I have a 1963 model year 292 L6 core. It has a rebuildable fuel pump. [If you can still get the kit.] The kit cost more than a complete later pump. I always figured to ''upgrade'' to a later style non-rebuildable fuel pump, when the time came to put it on the road, but now, if I can get an alcohol-compatible diaphragm for it, that will be better. [Big IF.]
Of course the L6 fuel pump is not the same part as an SBC. It works ''upside-down'' to the small block's orientation. But maybe 283s, 327s of the same vintage used a rebuildable style?
