Secondary Fuel Fillers

[Curt Sprenger]

For the last 12,000 miles I've run with the 10 micron secondary fuel
filters, 13/16" filter ID to the adapter.

The Bluebird Service Parts Sheet lists the fuel filter DDA#25010793, and
that x-refs to a Baldwin BF5800, and that is a 30 micron filter.

Should a 10 or 30 micron secondary fuel filter be used on the 8V92?

The reason I'm asking is I'm cleaning out some of the STUFF in one bay,
and the coach came with lots of Fram fuel filters, numbers P1146 and
P1147A. The P1146 is a 30 micron filter, ID to adapter is 1". The
P1147A is a 10 micron filter, ID to adapter is 13/16". Seems the P1146
is of no use to me, unless the 30 micron filter is the one to use and I
change the adapter to accept the filter ID of 1".
