I’m about to fit a filter king under the bonnet having picked up a used one. All seems in good condition, needs a replacement filter but I’m interested to know if the seals and top lid gasket is ethanol tolerant.

Does anyone know?

'Suitable for most fuels except methanol' is all it says in the Car Builder catalogue for Filter King on page 50.
Not sure that's much help but the catalogue can be downloaded or requested by post here:-

I wonder how long they’ve been ethanol tolerant for?

You can buy the seals and diaphragms as spares
