The old GM Glass Sediment Bowl style fuel filters*:
Housing # is: GM 854392 (I've seen them with AC and the same number, as well.)
Filter Elemets that work are as follows:
GM 854347
AC Delco GF124
Fram CG3
Fram has a whole list of other vendors' numbers that the CG3 will fit.
*Jim Carter sells these, as does American classic
