Anyone know anything about Grose-jets? Apparently they were an alternative to the needle and seat in automotive carburetors back in the day. Ellison uses them inside the "regulator" and one of ours is apparently leaking. It's in an EFS-4 mounted on an O-320 on our RV-3. Anyone know of a parts supply for these now that Ellison is apparently out of business?

Thanks for any help.
