Dear Editor,
I
switched to the spin-on oil fiLter on the
6-HP MiL Standard engine on my 15±CFM
compressor by using oiL fiLter kit, NSN
2805±01±189-9698. But the fiLt²r eLement
in the kit, NSN 2940±00-832±6054, was too
Long and r³sted on the mu´Ler.
I
found
that fiLter eLement, NSN 2940-00±586±
4792, wiLµ fit and is about 1% inches
¶hoRer, enough to cLear the mu´Ler.
