Hello, we recently purchased a 1946 ERCOUPE 415C that has the STC o-200 crankshaft conversion. Therefore it has an electric fuel pump and M7004-4, 4psi normally closed pressure switch that fills the header tank. It appears that the M7004-4 switch is not available. Does anyone know of a source or of the the replacement listed in the current STC. Thank you
